Dampen the sponge and wipe it over the product a few times, then squeeze the sponge several times to get foam. As you clean the dirt comes off onto the sponge - then just rinse the sponge out in water to remove the dirt. To remove the residue from the cleaned surface simply wipe it off with a damp or dry cloth or rinse it off with water. If necessary to get an even shine rub the surface again with a dry cloth.
If the product has become damp or sticky leave the lid off for a few hours to let it dry.
