Care and Cleaning

WARNING: Risk of property or product damage. Do not
use in-tank cleaners in your toilet. Products containing
chlorine (calcium hypochlorite) can seriously damage fittings
in the tank. This damage can cause leakage and property
damage.

Kohler Co. shall not be responsible or liable for any tank fitting
damage caused by the use of cleaners containing chlorine (calcium
hypochlorite).

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

sponge.
