Care and Cleaning

For best results, keep the following in mind when caring for your
KOHLER product:

•

Use a mild detergent such as liquid dishwashing soap and warm
water for cleaning. Do not use abrasive cleaners that may scratch
or dull the surface.

•

Carefully read the cleaner product label to ensure the cleaner is
safe for use on the material.

•

Always test your cleaning solution on an inconspicuous area
before applying to the entire surface.

•

Do not allow cleaners to sit or soak on the surface.

•

Wipe surfaces clean and rinse completely with water immediately
after cleaner application. 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.
