I use Castrol Super Clean for most of my cleanup, although it takes 2 or 3 attempts
sometimes. Also,someone pulls into my diveway and leaves oil spots every now and then. I
grab my squirt bottle of Super Clean and soak the spots, let it set for a few minutes and rinse it
off with nothing left. If I've got some spillage or oil spots on my driveway (and It's going to
rain soon), I just soak the area and after the rain, the problem is gone. For me, it works
better than Simple Green. The only thing is, even though Super Clean is supposed to be
biodegradable and all, there is an odor to it. If there is something that is comparable in
price,that works better, somebody enlighten me. Later on, Bill
