Oil spots on concrete removal

[hog_down]

If its a diesel, the oil has soot in it, and makes it tougher to clean from the 'pores' of the concrete. I'd try muratic acid or keep trying the various methods above. The cat litter usually helped me with the bigger stains.

Franks Red Hot, you can put that **** on everything.


I've always used Tide. Usually requires multiple applications over time.

So I guess that is bad? LOL.

I used some type of Concrete cleaner from Home Depot in the past. That crap was like acid and burned your eyes.

Acid doesn't break down the oil. Most likely the stuff from home depot was an alkali.
For our a/c coil cleaners, the acid based wont remove grease, but the alkali will. The acid based leave the coil shiny, so some like that, but if you work around restaurants you need to cut grease.

Tide...work for nascar

Get some of what we call "dry sweep" or unscented, colorless cat litter. Sprinkle over the oil and with a hard-bottomed boot or shoe, grind the litter into the oil spot...like you were doing "The Twist."

I've cleaned up gallons of oil this way in the Army.

Ah the dry sweep shuffle, done that many times myself

Guy at office said this stuff called 'chomp pull it out" got good reviews with pics on amazon...
Might give it a shot before i spray the driveway down with 30weight

Chomp works great...if you can find it. Home Depot used to carry it. If you find it PM me. I may have a bottle of it, if you need to see it.

Let us know how that works.

What about CLR? Comes in a grey square bottle?

In for results. I’ve got 1 stain that bugs the crap out of me and nothing will remove it
