My friend decided to try and burnout on the smooth concrete in my garage and now there's a huge skid mark. Is there a way to remove it?

Tried Goof-Off, Simple Green, and bleach and nothing worked.

Use your friends head and large amounts of pressure.

Well back in the day the cops would make us use scrubbrushes and soapy water to remove the marks from "thier road".

Muratic acid? Its highly corrosive and will eat anything short of steel and concrete, but it will corrode steel just from the vapors. Very dangerous, but as I understand its a common stone cleaner. I used some to eat aluminum off a crankshaft after a bearing spun. Then used it to clean years of oil from the garage floor. You definitely need to have goggles and long heavy gloves, the vapors will burn you themselves.

Toilet paper?

Doesn't the wife usually do the laundry?

A nice sharp blade. And lots of elbow grease with a bit of tar remover.

Make your friend clean up his own mess.

Do a burnout in reverse over the same marks that are there. It will erase them.

Yep, that should take care of it, you have to make sure you are exactly positioned over the original marks .

And don't forget to use the same brand and size tire. That way the reverse/erasing tread marks will match.

Wouldn't you need to have the tires mounted backwards then too, for it to really work?

LOL, that just reminded me of Ferris Bueller's Day Off..when Ferris and Cameron wreck the Ferrari...ah love that movie!

grinder with a wire brush? Or a sand paper? (belt sander?) I took some paint off a cement floor once that spilled by a belt sander.

Gasket cleaner might dissolve it and then use a scrub brush on it?

I'd use D'limonene first (can't remember the consumer product names that carry this ingredient - but it's the stuff that smells like oranges because it's the oil from the orange rinds), then follow with this stuff....

P.S. Carefull with the old rags that you use with the D'limonene. It's flammable stuff. Best to put them out in the sun to dry out after use. You know what oil/gas rags can do in the trash.

Why not try acetone? If that dont take it off, I dont know what will

Im sure there has to be a good concrete cleaner too.

liquid laundry soap cut it with a little water and keep it damp for a hour or three.


Acid will etc the surface. It's a standard prep for finishing concrete.

Those are rubber marks. I doubt that acids or cleaners are going to work on them. Don't most corrosives and powerful cleaners say to wear rubber gloves?

I would sand blast it myself. You will have to reseal the concrete after you are done.
