Having owned my share of “leakers” over the years, I have found this works well:

1) Pour a ring of cat litter (the non clumping kind) around the spot(s).

2) Pour mineral spirits over the stain to saturate it. The ring of litter above is to prevent the mineral spirits from running all over. Let set 5 minutes.

3) Resaturate the stain area again with more mineral spirits and then pour a light layer of cat litter over the whole stain.

4) Use a broom to work the litter around and soak up all the mineral spirits.

5) Sweep up all the litter and let the spot dry.

6) On heavy stains, you might have to repeat the process, but it does work!

Good Luck!
