Leave cat-liter or saw dust on it over night. Then sweep it up and put bleach on the spot.Anyone know the best way tom remove old oil leak spots from a car on a concrete street??
You'll be amazed how well Cat litter will do this. You can buy 25 pounds for about a dollar, and it'll pull the oil right out of the concrete. It can't be raining, though. Rain just turns it into mud.
The ';Awesome'; from the .99cents store, a wire brush, some knee pads and a lil muscle... ohh yeah and a little water too.
buy some powdered cement not the redimix stuff, make sure it will not rain anytime soon then put the dry cement mix on the oil and grind it in with a broom or the bottom of you shoe. Do this about 3-4 times and the oil spot along with a little help from the sun should go away.
since engine oil is originally from crude oil, the best is to use normal patrol first on the spot and brush it hard a bit, than apply a base material you use like your washing mechine detergents and apply brush as well, it most probably will remove the spots.
Bleach or vinegar. You'll have to saturate the spot a few times, but it'll work.
Muratic acid works good.Bleach is best .It won't burn your eyes, throat %26amp; nose as bad.
Kitty litter, grind it in with your foot let it absorb for a couple of days.
Brake cleaner works great!
I haven't tried this, but I have heard that coke is so strong that not only can it eat a hole in your stomach, but you can pour a new can of this on oil stains and leave it over night, and it should eat it up. I would think it may need to be repeated a night or two more for worse stains. Let us know how it goes.
