They say to start with water - but I'm thinkin that will warp my hardwood. And using vinegar or high-strength citrus decreasing solvents. Maybe trying hot iron or cold ice, then using a chemical like Isopropyl alcohol, paint thinner, xylol, lacquer thinner, or paint stripper.
Any of this stuff work? Will it damage my hardwood? What brands of sovents have anyone used that worked well? Thanks all.
