Turtle Wax Interior Cloth Dual Action is a combination of 2 different cloths with a sponge in between to clean the whole interior of the car. The waffled side cleans and dries streak-free any surface, the sponge absorbs water and helps keep the cloth moist for better cleaning, the terry side picks up the dirt. Use dry or damp, with or without detergents for leather, plastic, textiles or glass. Rinse after use, wring out gently and hang to dry. Hand washing recommended.
