One thing I think I forgot to ask was will the powder used to remove the diesel and gas stains just remove the new stains, or will it also remove the old stains? The ones that have been there a year or two. And once swept, or washed away can I then use hot water to do a much more thorough job contain it and recapture it from the service stations?
Thanks for your input.
