Can you pressure wash concrete?

Yes, outdoor concrete handles pressure washing well. Use a 25-degree nozzle and work evenly to avoid etching marks.

How do you seal a concrete floor?

Clean thoroughly first, then apply concrete sealer with a roller following the manufacturer's directions. Allow 24-48 hours to cure.

On raw, unsealed concrete it's okay. On polished, stained, or sealed concrete, vinegar can damage the finish.

Sweep weekly. Mop monthly. Treat oil stains immediately -- they get harder to remove the longer they sit.

Household

A clean concrete floors makes a bigger difference than you'd think. Here's the most effective method, plus the mistakes most people make.

1
Sweep and remove debris
Sweep the entire floor with a stiff broom to remove loose dirt, dust, and debris.
2
Treat oil and grease stains
Sprinkle baking soda or cat litter on oil stains to absorb the grease. Let sit for 24 hours, then sweep up. Apply Turbo Clean Degreaser to remaining stains.
3
Mop or scrub the floor
Mix Turbo Clean Degreaser with warm water. Mop interior floors or scrub outdoor concrete with a deck brush.
4
Rinse thoroughly
Mop with clean water indoors, or hose off outdoor concrete. Let the floor dry completely.

TIPFor garage floors, apply degreaser to oil spots and let it sit for 15 minutes before scrubbing for the best results.
TIPSeal concrete floors after cleaning to prevent future staining. Sealed concrete is 10 times easier to maintain.
TIPCola poured on oil stains and left overnight can help loosen old grease thanks to its phosphoric acid content.
