I have a bunch of articles out there about garage floor coatings and coverings, but I know that there are many of us that don’t have the money to buy things like that just because they want to. It’s unfortunate that those same people who do not have much money are the same that generally change oil in their garage, which is likely the most common way of staining garage floors. Car manufacturers don’t help; I used to have a Subaru that had a plastic cover that was almost impossible to remove, but went over the oil pan. There was a space for the drain bolt, but the oil, of course, never drained out of that hole, choosing instead to go every which way, hitting plastic and spraying all over the place. It was, to say the least, a mess.
