Help Needed: Cleaning Concrete

[tmleadr03]

I don't use a sand blaster, you could put out your eye.. Don't use brake cleaner, it contains vOC's and is a cancer risk, also potentially damaging by adsorption, absorption, injection, inhalation, and ingestion. Recharge your fire extinguishers. Eat your vegetables, and above all.,,

PSA: Spilling brake clean on your junk hurts.

Jeeze..if someone could have stated concrete or wood, I'm still assuming concrete.

A wire brush in a cordless drill should pull the paint out.

Stoddard solvent will release the grease, with some scrubbing with a hard bristled brush, and normal garden hose pressure spray down. BTW, are we talking about vehicle type grease, or barbecue grease... ? i.e. "Motorcycle leaked oil"....etc.etc.

I know bleach gets the blood stains out... oh wait, that's not the problem you're having.

not really, it takes the color out but leaves the trace, there's other more expensive chemicals out that take care of it. but they're $100/gallon

Might depend on the pressure washer.

I tried one of the "homeowner models" to strip paint off my gutters, outside clapboards, and concrete floor....nothing happened---it was worthless.

My neighbor loaned me his gasoline powered model.

Took the paint off my clapboards and stripped the paint off the galvanized gutters (down to the metal), with just water.
I had to be careful, as at first, with the "jet" nozzle. It put a hole through my fascia board, just below the gutter, until I learned how to use it better.
This was from about an 8' distance.

It took EVERYTHING off my garage floor with just water using the "fan" nozzle. It was literally like using a paint scraper to lift off the oil, grease, paint, etc.

While I can't guarantee it will work on your problem, I can say that my success depended on what kind of pressure washer I used.

This, I maintain properties for a living. I've never had to use more than a chemical related to the stain and a gas pressure washer.

This is very true.

This is very true.

KY jelly?

KY jelly?

No, but that is most likely a chemical used to create several stains.....which of course, have their own related "removers".

lol

This is very true.

So a pressure washer full of green chile will fix those pants I have in the garage?
