| Motor oil, grease |
Absorb fresh oil with a cloth or oil-dry. Damp mop with pH-neutral cleaner or a drop of dish soap. Usually removes completely. |
Absorb, then damp mop with neutral cleaner. Apply penetrating guard to treated area after cleaning. Old stains may require professional treatment. |
Don't use degreasers with high alkalinity — they can attack the surface over repeated use. |
| Road salt / ice melt residue |
Damp mop with pH-neutral cleaner. The key is frequency in winter — don't let salt accumulate and concentrate as water evaporates. |
Damp mop with neutral cleaner. Avoid citrus-based "ice melt removers" — they're often acidic and will etch the polish. |
Don't use acidic cleaners marketed for salt/ice melt removal — they make things worse on polished or coated surfaces. |
| Tire marks (rubber transfer) |
Usually wipes up with a damp cloth. Stubborn marks: apply a small amount of acetone or isopropyl alcohol to a cloth, wipe, then rinse with water immediately. |
Damp cloth or mop usually removes it. If stubborn, use a neutral degreaser diluted appropriately — test in an inconspicuous area first. |
Don't confuse tire marks (surface deposit) with hot-tire pickup (adhesion failure). Marks wipe off. Peeling requires professional assessment. |
| Paint (fresh latex) |
Wipe immediately with a damp cloth — latex paint on a sealed floor cleans up easily when fresh. |
Same — wipe immediately. Fresh latex is easy. Dried latex is much harder. |
Once latex paint dries, don't scrub aggressively with abrasive pads. Use a plastic scraper carefully, then solvent. |
| Paint (dried / oil-based) |
Plastic scraper to lift the bulk (not metal — it scratches). Then a solvent like acetone on a cloth, rubbed gently. Rinse with water immediately after. |
Plastic scraper carefully, then try warm water first. If needed, a neutral-pH paint remover. Avoid solvents on polished concrete — they can affect the guard. |
Never use metal scrapers. Never let solvents dwell — apply, wipe, rinse promptly. |
| Rust stains |
Commercial rust remover formulated for sealed surfaces, tested in an inconspicuous area first. Apply briefly, rinse thoroughly. For heavy rust, repeat rather than using a more aggressive product. |
This is trickier — rust can penetrate a depleted guard into the concrete itself. A poultice of rust remover and absorbent clay may help draw it out. Severe penetrated rust may require professional treatment. |
Don't use acidic rust removers (they often contain phosphoric or oxalic acid) on polished concrete without testing — they etch the surface. |
| Antifreeze / coolant |
Absorb and wipe up. Antifreeze is water-soluble and cleans easily from a sealed surface. Damp mop with neutral cleaner to finish. |
Same. Antifreeze is one of the easier automotive spills on either floor type — clean up while wet and it typically leaves no trace. |
Don't let it sit — antifreeze is colored and can stain polished concrete if allowed to dry. |
| Battery acid |
Neutralize immediately with baking soda before cleaning — pour a small amount over the spill to stop the acid reaction, then wipe and mop. Rinse the area thoroughly. Battery acid is aggressive and will attack a coated floor if left. |
Same immediate neutralization with baking soda is critical. Battery acid (sulfuric acid) will etch polished concrete if not neutralized immediately — this may require professional re-polishing of the affected area. |
Don't mop without neutralizing first — you'll spread an active acid across the floor. Act fast. |
| Concrete sealer / guard (spilled during DIY) |
Wipe up immediately before it cures. Once cured, it may need to be carefully abraded off — contact us before attempting aggressive removal. |
Wipe up immediately. Cured sealer on polished concrete usually needs to be buffed off by a professional to avoid scratching the polished surface. |
Don't try to dissolve cured sealer with solvents on a polished surface without professional guidance. |
