Prepare warm soapy water by adding a few drops of mild liquid detergent (Sunlight) to warm water. Use lint free cloths or a soft sponge to wash the surface of the powder coated furniture. Dip the cloth sponge in soapy water and wring out excess. Gently wipe the entire furniture surface, remembering to wash underneath the furnishing and in all cracks and grooves. Rinse the furniture with cold water and allow the furniture to dry completely.
