# Cleaning Products Guide ## When to Use Use this skill when the user presents one of the following specific situations: - User asks which product or ingredient to use on a named surface: "What should I use to clean my marble countertop?" or "How do I get hard water off my shower door?" - User wants to rationalize or reduce their cleaning supply cabinet -- they feel overwhelmed by specialty products or want to know the minimum effective set of products for their home - User asks about making DIY cleaning solutions from pantry or pharmacy ingredients (vinegar, baking soda, hydrogen peroxide, castile soap, borax) - User asks explicitly about cleaning product safety: whether two products are safe to mix, what to do after accidental mixing, ventilation requirements, or storage rules - User mentions a surface material and wants to know if a specific product will damage it: "Can I use bleach on my tile grout?" or "Will vinegar hurt my hardwood floors?" - User is moving into a new home and needs to build a starter cleaning kit from scratch - User is pregnant, has young children or pets, or has chemical sensitivities and needs guidance on low-toxicity or fragrance-free cleaning options - User asks about the difference between disinfecting, sanitizing, and cleaning -- and which they actually need **Do NOT use this skill when:** - User needs a room-by-room or weekly cleaning routine -- use `weekly-cleaning-schedule` instead - User needs to remove a stain from a garment, fabric, or laundry -- use `laundry-system` instead - User needs a full deep cleaning task checklist for a specific room -- use `deep-cleaning-checklist` instead - User is asking about commercial or industrial cleaning settings (restaurants, hospitals, office buildings) -- chemical concentrations, regulatory requirements, and equipment differ substantially from residential use - User has identified visible mold covering more than 10 square feet (approximately 3x3 feet) -- this requires professional remediation guidance, not product selection - User has a cleaning emergency involving a hazardous spill or accidental toxic mix and needs immediate safety guidance -- direct them to call Poison Control (1-800-222-1222 in the US) or emergency services first, then provide this skill's safety content --- ## Process ### Step 1: Gather the Three Critical Inputs Before Recommending Anything Never jump immediately to a product recommendation. Ask for or clarify these three inputs if they are not already stated: - **Surface material:** Not just the room or object, but the specific substrate. "Countertop" is insufficient -- is it granite, marble, quartz, laminate, butcher block, or concrete? "Shower" is insufficient -- are the walls ceramic tile, porcelain tile, natural stone, or acrylic/fiberglass? This distinction determines whether acidic cleaners will cause permanent damage. - **Type of soil or buildup:** Grease and cooking residue require alkaline cleaners. Mineral deposits (hard water, lime scale) require acidic cleaners. Soap scum (a combination of minerals and fatty acids) requires mildly acidic or chelating cleaners. Mold and mildew require oxidizing cleaners (bleach, hydrogen peroxide). General dust and light grime require only surfactant-based cleaners. Matching the cleaner chemistry to the soil type is the core of effective cleaning -- using the wrong chemistry just moves soil around. - **Household sensitivities and constraints:** Children under 2, pets (especially birds and cats, which are highly sensitive to aerosol sprays and phenol-based cleaners), pregnancy, respiratory conditions (asthma), or fragrance allergies all fundamentally change which products are appropriate. If the user has provided all three, proceed directly to Step 2 without asking redundant questions. ### Step 2: Classify the Surface by Its Chemical Tolerance Every surface falls into one of four chemical tolerance categories. This classification drives every product recommendation: - **Acid-intolerant surfaces (pH must stay above 7):** Natural stone (marble, granite, travertine, limestone, slate), cement grout, cast iron cookware, copper, zinc, and galvanized metal. Vinegar, citric acid, lemon juice, many bathroom cleaners, and lime-scale removers will etch, corrode, or strip the finish from these surfaces permanently. Even brief contact with a pH-4 cleaner can etch polished marble visibly. - **Alkaline-intolerant surfaces:** Aluminum, anodized aluminum, and some natural fibers. Strong alkaline cleaners (oven cleaners, drain openers, washing soda) corrode aluminum, causing pitting and discoloration. - **Solvent-intolerant surfaces:** Acrylic, plexiglass, some plastics, lacquered finishes, and painted surfaces. Acetone (nail polish remover), strong alcohol (above 70% concentration), and petroleum-based solvents will craze, cloud, or dissolve these surfaces. - **Moisture-intolerant surfaces:** Solid hardwood, cork, bamboo (unsealed), unfinished wood, and paper-based laminate. Excess water -- not just soaking, but even repeated damp wiping without drying -- causes swelling, warping, delamination, and mold growth inside the material. Multi-surface households often span all four categories. When a user has both acid-intolerant surfaces (granite) and surfaces that benefit from acid cleaning (hard water on shower tile), make this distinction explicit so they don't cross-contaminate products between rooms. ### Step 3: Match Product Chemistry to Soil Type Use this decision framework to identify the correct product class before naming specific ingredients or recipes: - **Alkaline cleaners (pH 8-13):** Best for grease, oils, protein-based soils (food, blood), soap scum (partial), and general grime. Includes dish soap, all-purpose sprays, degreasers, oven cleaners, and baking soda. The higher the pH, the stronger the degreasing action -- dish soap (pH ~7-8) for light grease, a proper degreaser (pH 10-12) for kitchen exhaust filters and stove grates. - **Acidic cleaners (pH 2-6):** Best for mineral deposits (hard water, lime scale, calcium, rust), soap scum (the mineral component), and brightening grout. Includes white vinegar (pH ~2.4), citric acid solutions, cream of tartar, and commercial lime/calcium/rust removers. Contact time matters: acidic cleaners need 5-30 minutes of dwell time to dissolve mineral deposits, not just a quick spray-and-wipe. - **Oxidizing cleaners (disinfectants and bleaching agents):** Bleach (sodium hypochlorite), hydrogen peroxide, and oxygen bleach (sodium percarbonate) work by releasing active oxygen or chlorine that destroys cell membranes and organic compounds. Best for mold, mildew, stain bleaching on white or colorfast surfaces, and disinfection. Concentration and contact time are critical: bleach solution must be at minimum 1,000 ppm (approximately 1/4 cup per gallon of water) for disinfection and must contact the surface for at least 10 minutes. - **Surfactant-based cleaners (neutral pH 6-8):** Dish soap, castile soap, and most all-purpose sprays at neutral pH. Best for everyday cleaning where disinfection is not required. Surfactants surround and lift dirt without chemical reaction. These are the safest option for delicate or chemically sensitive surfaces. - **Abrasive cleaners (mechanical action):** Baking soda (very mild, 2.5 Mohs hardness), powdered cleanser with calcium carbonate, or cream cleanser. Used to scour mineral deposits, stains, and stuck-on residue from durable surfaces. Never use on surfaces with a Mohs hardness below 4 (soft stone, acrylic, glass cooktops). The key rule: if the abrasive is harder than the surface, it will scratch. ### Step 4: Construct the Surface-Product Matrix for This User's Specific Home Build a table (see Output Format) populated only with the surfaces the user has mentioned. Do not pad the table with irrelevant surfaces. For each surface, provide: - The recommended product type with its active ingredient and approximate pH range - What NEVER to use and the specific damage mechanism (not just "don't use this" but "this will permanently etch the finish by dissolving the calcium carbonate in the stone") - A specific, measurable DIY alternative with exact ratios ### Step 5: Build the Minimal Essential Product List The default target is 5-7 products. More than 7 products in a home cleaning kit increases safety risk (accidental mixing, children accessing multiple chemicals) and cost without meaningfully improving cleaning outcomes. The typical complete home kit consists of: 1. A pH-neutral all-purpose spray (covers 60% of routine cleaning needs) 2. Dish soap -- which doubles as a stone-safe cleaner at low dilution (1 tsp per quart water) 3. White distilled vinegar -- acidic cleaner for hard water, glass, stainless steel, and disinfecting at full strength 4. Baking soda -- mild abrasive, deodorizer, and alkaline booster 5. Hydrogen peroxide (3% from pharmacy) -- disinfectant, grout brightener, stain remover 6. A bathroom cleaner (mildly acidic, soap scum and mildew) -- the one product type that genuinely requires purchase, as the combination of acids, chelators, and surfactants is hard to replicate with pantry ingredients at full efficacy 7. A toilet bowl cleaner (angled-bottle design for under-rim application; can be eliminated if user is willing to use baking soda + vinegar method with longer dwell time) **Optional but genuinely useful:** Microfiber cloths (replace paper towels for most tasks, washable, leave no lint), a grout brush with stiff nylon bristles, a squeegee for shower glass. If the user's home has no natural stone and no hardwood, the list can collapse to as few as 4 products: dish soap, vinegar, hydrogen peroxide, and a bathroom cleaner. ### Step 6: Provide DIY Recipes Specific to the User's Surfaces Only provide DIY recipes that are relevant to surfaces the user has mentioned. Each recipe must include: - Ingredient quantities in standard measurements (cups, tablespoons, parts) - Mixing method (does order matter? shake vs. stir?) - Dwell time required - "Use on" and "Do NOT use on" lists - Shelf life of the mixed solution Note for every relevant recipe: a freshly mixed solution is always more effective than a stored one. Many DIY solutions (especially vinegar-based) lose efficacy within 1-2 weeks. ### Step 7: Deliver the Safety Section -- This Is Mandatory in Every Output The safety section cannot be omitted or abbreviated. It must appear in every output from this skill, regardless of how narrow the user's question was. Structure it to be scannable in an emergency: use bold text for the most dangerous combinations and lead with the highest-risk scenarios. Include: - The six most dangerous product combinations and their specific chemical reactions - Ventilation requirements for any product generating fumes - First-response instructions for accidental mixing or exposure - Storage rules, especially for households with children or pets ### Step 8: Recommend Surface Sealants and Preventive Measures Where Applicable For any surface that requires periodic sealing or protective treatment, include this information alongside product guidance. These recommendations dramatically reduce cleaning difficulty: - **Granite and marble:** Seal annually with a penetrating stone sealant (impregnating sealer). Test current seal by placing a few drops of water on the surface -- if it beads for at least 5 minutes, the seal is adequate. If it absorbs in under 30 seconds, reseal immediately. - **Tile grout:** Seal with a penetrating grout sealer every 1-2 years after cleaning grout thoroughly. Epoxy grout does not require sealing. - **Glass shower doors:** A hydrophobic coating (rain-repellent formulations designed for shower glass) applied every 3-6 months dramatically reduces hard water buildup. A squeegee after each shower is the single highest-ROI preventive habit -- 30 seconds of squeegee time prevents 90% of mineral deposit buildup. - **Hardwood floors:** Reapply a hardwood floor refresher compatible with the finish type (polyurethane vs. oil-based finish) every 2-3 years. Never use wax on polyurethane-finished floors. - **Stainless steel appliances:** A thin coat of mineral oil applied after cleaning provides a barrier against fingerprints and water spots and extends the time between cleanings. --- ## Output Format Produce the following structured output.

[Step 1] 2. [Step 2] 3. [Step 3] ``` --- ## Rules 1. **Never name a product brand -- describe chemistry.** Recommend "a mildly acidic bathroom cleaner with citric acid or hydrochloric acid as the active ingredient" rather than any brand name. Users' product availability varies, and brand allegiance creates dependency on specific products rather than understanding. 2. **The Safety section is mandatory in every single output.** Do not abbreviate it because the user's question was narrow. A user who only asked "what cleans stainless steel?" may be about to use bleach and then immediately spray a glass cleaner containing ammonia. The safety section prevents that. Place it at the end but make it visually prominent. 3. **Acidic cleaners permanently damage natural stone -- say so explicitly and mechanically.** Do not just say "don't use vinegar on granite." Explain: "Vinegar has a pH of approximately 2.4, which dissolves calcium carbonate. Granite, marble, travertine, and limestone are calcium carbonate-based rocks. Acid contact causes microscopic etching that appears as dull spots, permanently altering the polished surface. This damage is not reversible by re-cleaning -- it requires professional re-polishing." 4. **Always specify dwell time for every product recommendation.** A cleaner that is wiped off in 5 seconds provides almost no disinfection and minimal soil removal for anything other than light dust. Disinfecting bleach solution requires 10 minutes of wet contact. Lime scale removers require 15-30 minutes. Grout cleaners require 5-15 minutes. Dwell time is the single most common reason DIY cleaning "doesn't work." 5. **Distinguish between cleaning, sanitizing, and disinfecting -- and tell users which they actually need.** Cleaning (removing visible soil with surfactant) is sufficient for 80% of home surfaces. Sanitizing (reducing bacteria by 99.9%) is appropriate for food-contact surfaces like cutting boards and counters near raw meat. Disinfecting (killing 99.999% of pathogens including viruses) is appropriate for toilet surfaces, sick-room surfaces, and areas with confirmed contamination. Most rooms need cleaning, not disinfection. Over-reliance on disinfectants damages surfaces and contributes to resistance. 6. **Dilution ratios are not optional.** Never recommend a product without specifying the dilution. "Use bleach" is dangerous and vague. "Mix 1/4 cup of chlorine bleach (sodium hypochlorite, standard household concentration of 5.25-8.25%) per gallon of room-temperature water to produce a 1,000 ppm solution appropriate for disinfection" is actionable and safe. Hot water degrades bleach -- always use room-temperature water. 7. **Never recommend steam mops on hardwood or luxury vinyl plank (LVP) flooring without a major caveat.** Steam mops operate at temperatures above 200°F and force pressurized moisture into floor seams. On hardwood, this causes cupping, warping, and finish delamination over time. On LVP, high heat can warp planks and void warranties. This recommendation (steam on hardwood) appears frequently online and causes expensive, irreversible damage. 8. **Mixing two different drain cleaners is one of the most dangerous things a homeowner can do -- address it proactively.** Enzymatic drain cleaners, sulfuric acid drain openers, sodium hydroxide (lye) drain openers, and bleach-based drain cleaners can each react violently with one another, generating extreme heat, pressurized steam, or toxic gas in an enclosed pipe. If the user mentions drain cleaning, include an explicit warning: if one product fails, flush with copious water for at least 5 minutes, wait 30 minutes, and call a plumber before adding any second product. 9. **Birds, cats, and reptiles require specific product restrictions -- ask proactively if user mentions these pets.** Birds are extraordinarily sensitive to volatile organic compounds and aerosolized chemicals. Non-stick cookware heated above 500°F releases PTFE gases fatal to birds in the same room. Aerosol sprays, strong bleach fumes, and oven cleaner fumes can be fatal to pet birds even in adjacent rooms. Phenol-based disinfectants (many pine-scented cleaners) are toxic to cats because cats cannot metabolize phenols through their liver. If user mentions birds or cats, flag these specific risks. 10. **The "natural = safe" assumption must be corrected.** Vinegar is corrosive to stone and dulls hardwood finishes. Baking soda is an abrasive that scratches soft surfaces. Hydrogen peroxide bleaches colored fabrics and grout. Borax is a skin and eye irritant harmful to pets and small children if ingested. Essential oils can be toxic to cats (especially tea tree, eucalyptus, and citrus oils) and can leave residue that attracts dirt. When a user wants "all-natural" products, provide the options while accurately characterizing their real limitations and risks. --- ## Edge Cases ### Natural Stone (Marble, Granite, Travertine, Limestone, Slate) This is the most common source of permanent, expensive cleaning damage in residential homes. The defining characteristic is calcium carbonate or silicate composition combined with a polished surface that is easily etched. **Correct approach:** pH-neutral cleaner only (pH 6-8). In practice, this means plain warm water with 1-2 drops of dish soap per quart, wiped with a microfiber cloth and dried immediately. Stone-specific cleaners are pH-formulated and stone-safe but not required if dish soap dilution is used correctly. **What never to use and the exact damage mechanism:** - Vinegar (pH 2.4): etches polished calcite crystals, creating permanent dull spots visible in raking light within minutes of contact - Lemon juice (pH 2-3): same mechanism as vinegar, slightly slower - Bathroom sprays with citric or phosphoric acid: same mechanism, often used accidentally because grout needs acid cleaning and the acid gets sprayed on adjacent stone - Bleach at full concentration: discolors stone and strips sealer - Ammonia-based cleaners: strips sealer and damages stone finish over repeated use - Abrasive scrubs: scratches the polished surface **Annual maintenance:** Apply a penetrating (impregnating) stone sealer -- not a topical coating. Topical coatings peel; penetrating sealers fill the pore structure of the stone. Test the seal with the water bead test: 3-5 drops of water should bead on the surface for at least 5 minutes. If water absorbs within 1-2 minutes, the stone is unsealed and highly vulnerable to staining and etching. **For etching that has already occurred:** Over-the-counter stone polishing powder (tin oxide or aluminum oxide based) can polish out light etching with a felt pad and a drill attachment. Deep etching requires professional diamond polishing. This is a $200-600 job for a typical countertop. ### Households with Children Under 5 or Pets Product selection changes substantially in these households. The priority order is: safety first, efficacy second. **Products to eliminate entirely:** - Aerosol sprays of any kind near children under 2 (inhalation of fine droplets) - Any cleaner containing phenol (often found in pine-scented or "hospital-grade" disinfectants) if cats are present -- phenols are hepatotoxic to cats - Products containing benzalkonium chloride near pet food and water bowls or pet bedding -- toxic to reptiles and amphibians, irritating to birds - Bleach used at full concentration anywhere with floor access by toddlers or pets -- always dilute to the 1/4 cup per gallon disinfecting concentration and rinse surfaces that will have skin contact **Safe alternatives that maintain hygiene:** - 3% hydrogen peroxide from a pharmacy is an effective disinfectant for food-contact surfaces, toilet seats, and high-touch areas when allowed to sit for 10 minutes. It breaks down to water and oxygen, leaving no toxic residue. - A 70% isopropyl alcohol solution disinfects hard non-porous surfaces quickly and evaporates without residue. Not for use near open flames or on rubber, acrylic, or some plastics. - Steam cleaning (with appropriate surface restrictions noted in Rule 7) kills pathogens without any chemical residue on sealed tile, grout, and toilet surfaces. **Storage requirement:** All cleaning products -- including vinegar, baking soda solutions in spray bottles, and hydrogen peroxide -- must be stored in a locked cabinet or on shelves at least 5 feet from the floor. Even low-toxicity products like vinegar cause esophageal and eye damage if a toddler ingests or splashes a concentrated form. ### Hard Water Regions (Water Hardness Above 180 mg/L or 10.5 gpg) Hard water is defined as water containing more than 120 mg/L of dissolved calcium and magnesium carbonate. Above 180 mg/L (hard to very hard), the mineral buildup on fixtures, shower glass, and faucets is significant enough that standard all-purpose cleaners are completely ineffective -- they do not react with mineral scale. **Diagnosis:** If you see white, chalky, or slightly yellowish crusty deposits on faucets, showerheads, or glass, the problem is mineral scale, not soap scum. Soap scum is a whitish film that smears; mineral scale is hard and crunchy. **Treatment protocol by severity:** - **Light scale (less than 3 months of accumulation):** Spray undiluted white vinegar on the surface, let sit 15-30 minutes, scrub with a non-scratch sponge, rinse thoroughly. For faucet aerators, soak the aerator in a small bowl of undiluted white vinegar for 30-60 minutes.
