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.

For detailed cleaning information and products to consider, visit www.kohler.com/clean. To order Care & Cleaning information, call 1-800-456-4537.
