How to remove grease / oil stains from concrete
This guide is for Concrete. It does not create separate pages for fresh, dried or set-in states.
Blot or lift the grease / oil first, then use the smallest amount of a cleaner labelled for concrete. Keep the surface rule in view: Absorb a fresh liquid before wiping. Use a product and method labelled for concrete, then rinse and dry the area as the surface allows.
Keep it simple.
- absorbent material
- concrete-labelled cleaner
- rinse water
- absorbent paper or cloth
- mild detergent or labelled degreaser
- clean rinse cloth
Act before it dries.
- Lift standing oil with an absorbent material; do not wipe it deeper. Absorb a fresh liquid before wiping. Use a product and method labelled for concrete, then rinse and dry the area as the surface allows.
- Apply the compatible detergent to the cleaning cloth or surface, not indiscriminately to a porous backing. Absorb a fresh liquid before wiping. Use a product and method labelled for concrete, then rinse and dry the area as the surface allows.
- Rinse or blot residue and dry fully. Absorb a fresh liquid before wiping. Use a product and method labelled for concrete, then rinse and dry the area as the surface allows.
Use less, check more.
- Remove any crusted residue without scraping the surface. Absorb a fresh liquid before wiping. Use a product and method labelled for concrete, then rinse and dry the area as the surface allows.
- Use a labelled product suited to the surface and follow its dwell-time instructions. Absorb a fresh liquid before wiping. Use a product and method labelled for concrete, then rinse and dry the area as the surface allows.
- Repeat only after the surface is dry and the finish still looks normal. Absorb a fresh liquid before wiping. Use a product and method labelled for concrete, then rinse and dry the area as the surface allows.
Work in this order.
- 01
Read the material or care label and test the method in an inconspicuous spot.
- 02
Remove excess grease / oil by blotting or lifting; do not spread it.
- 03
Apply only the concrete-compatible product or detergent called for by the source and label.
- 04
Rinse or blot away residue when the label or surface method calls for it, then dry fully and inspect.
- solvents near flame or poor ventilation
- over-wetting upholstery, carpet or a mattress
- strong degreasers on a finish without a patch test
- pushing oil deeper by wiping first
- wire brushes that can leave metal particles
- solvents or acids without a labelled concrete use and ventilation
- Use one cleaning product at a time. Never mix bleach or any disinfectant with another cleaner.
- Ventilate and use gloves or eye protection when the product label calls for them.
- If the finish, color, backing or odor changes, stop and use the maker or a professional cleaner.
If the grease / oil remains after one labelled treatment, do not escalate to a stronger household chemical by guesswork. Check the care guide for concrete or use a professional service.
Why this guide says that.
Grease / oil guidance was checked against the cited source and narrowed to the Concrete scope. Chemical combinations not required by the source were intentionally omitted.
