For best results, keep the following in mind when caring for your KOHLER product:
•Always test your cleaning solution on an inconspicuous area before applying to the entire surface.
•Wipe surfaces clean and rinse completely with water immediately after applying cleaner. Rinse and
dry any overspray that lands on nearby surfaces.

•Use a soft, dampened sponge or cloth. Never use an abrasive material such as a brush or scouring
pad to clean surfaces.

only warm water to clean. Dry with a cotton cloth or soft sponge.
