Best way to clean up oil stains on garage floor?

[maskedSONY]

A friend of mine recently got rid of a car that was pretty much a total wreck. That car leaked a fair amount of oil onto his garage floor and now he's seeking ways to clean it up. Normally I'd toss kitty litter on the damn thing, but are there grease cleaners out there which will make a concrete surface look respectable again?

if your boy is concerned about the look of his garage floor....does he measure his grass with a ruler prior to cutting it?

just mop it up/KL it and be done with it...

Have this link saved when I was looking.

brake cleaner didn't do squat for me.

Seriously though. No need to waste hours on a lost cause. Fine concrete is just the right porosity to always keep some of the stain. Epoxy the garage as a weekend project, and bam!

Call BP about the spill?



Try concrete etcher....

I've had good luck getting oil stains off concrete by using copious amounts of fresh human blood.

I've been wondering about my garage as well. I have an oil spill that seeped so far into the concrete my pressure washer didn't do anything. Can I epoxy straight over that? That's pretty much the only reason I haven't done mine yet.

This and then muriatic acid

Tide will do a better job of cleaning up recent and semi-recent spills. Engine Degreaser will get some of an old stain. It will never go away completely if it's been there long.

Yup! Muratic Acid, but make sure you're well protected when applying.

I had looked into doing an epoxy coating on our garage floor before we moved in but it was the the middle of winter and that's not a good time to do it due to the temp.

Part of the prep for applying epoxy is to clean the floor and, for older floors, etching.

What strength or molarity? Secondly, I haven't heard the term muratic acid in ages! But I guess I'll have to find some. (FYI it's another name for hydrochloric acid.)

Muriatic acid will etch the concrete, right?

Yes, but be careful! It will rust any bare metal if it's exposed to it.
