This may be a little off the beaten path, but years ago I cleaned some oil spots off a concrete driveway using cat litter and it worked beautifully. It actually made the spot where it was spread cleaner than the surrounding area that hadn't been oily. The clean spot looked much like newly poured concrete.
I've recently tried it again, but this time on asphalt and it hasn't done much of anything. I've even tried three different cat litters, since many of them now have additives that weren't used decades ago, like being scented or non-clumping and not just the plain old clay litter of the past.
Is the problem that I haven't found the right cat litter or is it that I'm trying to use it on asphalt instead of concrete? Obviously, the asphalt is already oil-based and likely much more porous than concrete, so maybe it's never going to work. Does anyone have any good tips for cleaning oil or gas stains on asphalt?
Thanks.
