Klean-Strip Denatured Alcohol is an effective solution for cleaning glass and other non-porous surfaces. It is not intended for use or sale as a paint thinner. Klean-Strip solvents and thinners are designed to be mixed into wet paint, varnish, stain, and similar finishes to adjust consistency and improve application. They are also highly effective for cleanup after painting tasks. Engineered for professional use, Klean-Strip products are formulated to remove layers of old paint, tackle tough spills, and help restore surfaces—providing powerful results where ordinary cleaners fall short.
