Klean-Strip® Premium Stripper Non-Methylene Chloride is a patent-pending formula that takes 15 minutes to dissolve decades of built-up finishes. Klean-Strip® Premium Stripper removes multiple layers of latex and oil-based paint, polyurethane, epoxy, varnish and shellac from wood, metal and masonry surfaces. The thick, brushable paste clings to vertical surfaces without runs or drips.
