Care and Cleaning (cont.)
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.
•
Do not allow cleaners to soak on surfaces.
•
Use a soft, dampened sponge or cloth. Never use an abrasive material such as a brush or scouring
pad to clean surfaces.
•
For Artist Edition Toilets: Treat your decorative product just as you would treat your fine china.
DO NOT use bristle brushes or abrasive-backed sponges. They will scratch decorative surfaces. Use
only warm water to clean. Dry with a cotton cloth or soft sponge.
