Fine Microfibre Mitt is specifically designed for the correct application of Surface Prep and Wash andamp; Seal.

Microfibre wash mitts and cloths are designed to lift the dirt off the surface not push it along the surface as a sponge or regular cloth will do. Always rinse the wash mitt in clean water after use and before reuse. Wash mitts may be washed after use in a washing machine however should never be placed in a tumble dryer. As with other microfibre cloths, powdered detergent and fabric softeners should not be used.
