If You Can't Remove The Garage Floor Stain...

If nothing else, you can always buy a garage floor covering whenever you do get the money. These can be expensive, though. Sometimes you can use an epoxy garage floor coating once the floor is cleaned to the kit's specifications, but you'll have to find one that supports this. There's also the option of just buying a set of snap-together garage floor tiles, or one of the many garage floor mats out there, and not worrying about the staining, or even future stains as both garage floor tile and mats are generally stain resistant. However, if you end up with a really big stain that just won't go away, don't use the peel and stick type of tiles since the sticky stuff won't last very long placed up against oil. The stain may not want to come out at your behest, but it will have no problem eating the bottoms of garage floor paint or other garage floor coverings.
