XL 4200 Cleaner is a non-alkaline, non-flammable clear liquid surfactant solution that will aid the lifting of latex, acrylic and pressure sensitive adhesives from flooring surfaces. It also aids in the removal of chewing gum. It works by penetrating and emulsifying the adhesive at the contact surface to loosen the bond. For best results, use at room temperature, carefully read and follow instructions for use. Always test a small area first before using.
