accidentally spilled some oil whne doing the change and got a big oil spot

what will take oil (brake fluid t00)
out of concret and asphault

its been there for 2 days and i need it gone quick

 

kitty litter.
409 cleaner
gas. caution FIRE hazard.

 

hmm, thought gas would make it worse. will have to try it myself.
what if its been there for a few months

 

don't know about on asphalt, but diesel is an excellent degreaser...

 

formula 88 degreaser has worked for me. although i can see diesel working too though i havent tried it

 

we used diesel on the shrimpboat to clean grease, oil, tar, anything. but that was on painted steel, so i don't know about your driveway. test it and make sure it won't FUBAR it then go for it...mix it with some dawn and water, should git r done.
