Success with cleaners and procedures is dependent upon such factors as the hardness and temperature of the water, using exact measurements of ingredients, changes in cleaning formulas and the condition of the product being cleaned. Since there are variations within these factors, Kohler cannot guarantee the effectiveness of the formulas mentioned.
KOHLER® countertops are supplied pre-sealed; however, it is recommended that you test the seal after a few years of use. Simply apply a few droplets of water to the surface. If the water beads, your countertop is maintaining its seal. If the water soaks into the countertop, resealing should be considered.
