An oil drip does not stay a drip. It soaks into the slab, spreads under tires and turns into a dark stain that pressure washing will not lift. The stain sits where the car parks every night, and every visitor sees it before they see the house. The best concrete oil stain remover pulls the oil out of the concrete instead of washing the surface, and this guide compares removers for that job, from microbe powders to poultice liquids.

Buying guide: best concrete oil stain remover
Powder or liquid
Oil Eater and both CHOMP! picks are liquids: pour a small amount onto the stain and let it dry. CAF EXIMO and ACT are dry powders: CAF EXIMO applies directly with no mixing or rinsing, and ACT is swept over the stain and misted with water. Powders suit a garage shelf and a waterless job; liquids suit a stain you can pour over and leave.
Microbes or poultice
Oil Eater, CAF EXIMO and ACT break the oil down with microbes or a natural process: Oil Eater uses oil-eating microbes, CAF EXIMO converts contamination into water and carbon dioxide over time, and ACT uses its ACT TF Formula with microbes. CHOMP! uses a poultice technology that draws the contamination out as the formula dries, then brushes away like chalk dust.
How long it takes
Oil Eater works overnight: pour, let it dry to a powder and sweep away. CHOMP! works as it dries, then brushes away like chalk dust, with no time stated. ACT takes 2 to 4 weeks to completely remove stubborn oil spills, though the product covers the stain from view during that time. CAF EXIMO states no time figure, only that the treatment works over time.
Coverage
Only ACT states coverage: 1 lb covers 100 sq ft. The packs run from 0.75 lb for CAF EXIMO to 2.5 lb for ACT, with Oil Eater and the single CHOMP! at 32 Fl Oz and the CHOMP! 2-pack at 2 x 32 Fl Oz. The other listings state no coverage figure, so buy for the size of the stain you have.
Safe around pets and plants
ACT states it is safe to use around people, pets and plants, with no toxic chemicals and no bleach, and it is USDA Certified. Oil Eater states a biodegradable formula with no harsh acids, bleaches or hazardous materials. CHOMP! states it does not contain bleach, acid or other potentially hazardous materials.
