Stains on a Driveway...

Completely Random... But I thought I would ask in case anyone has some good tips. I drive an old Caddie that is currently leaking lots of Transmission fluid. I am consistently adding to it until I can get the leak fixed... But unfortuanetly my drip pan was knocked while I was pulling out of the driveway...and I ahve a Tranny Fluid Mess all over my driveway. I was thinking about renting a pressure sprayer... But are there any tips on the best way to clear an oil or transmission fluid stain from your driveway?

Pour cheap cat litter all over it grind it in with your shoes and then sweep it up. You'll never know the Tranny fluid was there. :D

Awesome ... I would have never thought. I knew it would pay to ask!:D

We carry kitty litter on the fire trucks for this reason. When we go on wrecks and fluids have spilled we put this down to soak everything up. Works pretty good but you will probably still need a pressure washer to get the stain out.

So this cat litter thing works by soaking up liquid that has not dried? Is there something I should scrub the stain with first that won't leave a white spot on the driveway?
Thanks again.

the other thing we use to use when I work at the auto shop when washing the bays down was Castrol Super Clean. You can spray it on scrub the concrete down and then hose it off

Bentonite, the mineral of a thousand uses, (which is in cat litter) will soak up anything. Put that down first, sweep it off then attack any stain with a cleaner. Bentonite is a smectite clay that will wash off and wont itself stain or bleach anything.

I work for the largest distributor of the clays that go in to cat litter, so I've learned a few things about it.

Tranny fluid should come up pretty easily with kitty litter or just rinsing. The stuff is the most caustic stuff in a car. If you ever get your hands really greasy or covered in a poly paint you can use tranny fluid to get the big stuff off your hand and out from under your nails. At first it looks all messy, but after scrubbing your hands together then rinsing it off you would be surprised at how clean your hands are. Now I don't recommend doing this every day as the stuff is toxic and excessive exposure will get you sick! If where it got on the concrete looks discolored the issue probably isn't tranny fluid stains as much as the tranny fluid removed any color dye in the concrete. Uncolored concrete is grey, but most people like a tan drive which requires a dye being used in the concrete mix. If this is the case you have two choices. Use tranny fluid to strip all the color out of the surface of the concrete which will probably get you in trouble with the EPA and every tree hugger within 1000 miles or paint the driveway with concrete paint, but even that requires you to wash your drive with a muric acid mixture to make sure it is absolutely clean and the paint will stick.
