A friend of mine was doing some PVC work in his kitchen. Slopped on the purple primer, and some dropped on the hardwood floor.
His grand kids love the really kewl colors. But, SWMBO wants the purple spots out.
He's tried gasoline on a paper towel, or alcohol. I suggested clear primer, on a paper towel, to redissolve the purple dye.
What has anyone found to work? Flamethrower is not an option at this point.
