Cleaning Chemical Compatibility Reference
Overview
Cleaning chemicals interact dangerously when mixed. Bleach + ammonia produces toxic chloramine gas - has hospitalized cleaners + killed in extreme cases. This is the in-truck card showing which products to NEVER combine, and which surfaces each chemistry is safe for.
Reference Table - Dangerous Combinations
| Combination | Reaction | Symptom on exposure |
|---|---|---|
| Bleach + ammonia | Chloramine gas | Coughing, eye + lung irritation, fatal in confined space |
| Bleach + vinegar | Chlorine gas | Burning, eye + respiratory damage |
| Bleach + rubbing alcohol | Chloroform + HCl gas | Headache, dizziness, organ damage |
| Hydrogen peroxide + vinegar | Peracetic acid | Skin + lung irritation; corrosive |
| Hydrogen peroxide + bleach | Generates heat + oxygen rapidly | Splash + steam burn risk |
| Different drain cleaners (acid vs alkaline) | Violent reaction + boiling | Major splash hazard |
Safe alone, dangerous when combined: even when a product label is safe, NEVER mix products unless the label explicitly says so. The classic dangerous combinations are when household cleaning agents - already separately safe - are combined unintentionally.
Reference Table - Surface Compatibility
Acidic cleaners (vinegar, citric, descalers):
- ✓ Hard water stains
- ✓ Soap scum
- ✓ Toilets (interior), tile (ceramic only), chrome, stainless steel
- ✗ Natural stone (marble, travertine, slate, granite) - ETCHES
- ✗ Wood floors - strips finish
- ✗ Cement-based grout (over long exposure)
- ✗ Aluminum - corrodes
- ✗ Electronics
Alkaline cleaners (degreasers, soap scum removers, baking soda):
- ✓ Grease + oil cleanup
- ✓ Carpet pre-spray
- ✓ Kitchen surfaces, range hoods, oven exteriors
- ✗ Aluminum - corrodes (esp. dishwasher detergent on aluminum)
- ✗ Wool carpet - degrades fibers
- ✗ Some painted surfaces - strips finish
Bleach (sodium hypochlorite):
- ✓ Disinfection of hard surfaces (when diluted per label)
- ✓ Mildew removal from tile + grout
- ✓ White fabric stains
- ✗ Mixing with anything else
- ✗ Colored fabric - permanent color removal
- ✗ Natural stone - etches + discolors
- ✗ Stainless steel (prolonged contact corrodes)
Hydrogen peroxide:
- ✓ White grout brightening
- ✓ Old organic stains (blood, urine)
- ✓ Disinfection alternative to bleach
- ✗ Mixing with vinegar OR bleach
- ✗ Carpet (color-removal risk; always test first)
- ✗ Sensitive electronics
Solvents (P.O.G., citrus-based, mineral spirits):
- ✓ Oil-based stains, asphalt, tar, ink
- ✓ Adhesive residue
- ✓ Some carpet spots (oil-soluble)
- ✗ Synthetic surfaces (some plastics melt)
- ✗ Floor finishes - strips polyurethane
- ✗ Painted surfaces - strips paint
Safety Best Practices
- One product at a time. Apply chemistry; rinse with plain water; only THEN apply a different chemistry. Never overlap.
- Ventilate. Open windows + run exhaust fans while using any cleaner.
- PPE. Eye protection + gloves for any product stronger than dish soap.
- Storage. Acidic + alkaline products on opposite ends of the truck.
- Original containers. Don't decant into unlabeled containers - confusing them is how mixing accidents happen.
- SDS sheets. Keep Safety Data Sheets accessible for every product in use. OSHA-required for crews.
Chloramine gas (from bleach + ammonia) has hospitalized many cleaning crews. The mixture happens unintentionally - a customer asks "can you also use this product I have?" and the answer is YES if you can verify it isn't ammonia-based, NO if you can't. When in doubt, never mix; use your own products only.
