Care and Cleaning

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

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.
The ideal cleaning technique is to rinse thoroughly and blot dry any water from the surface after each use.
Use a soft nylon brush on slip-resistant surfaces. Be sure to use a water-soluble cleaner (dissolves 100% in water).
Do not use powdered cleaners unless the cleaner is fully dissolved in water. Solid substances can block the airjets.
Do not use full strength bleach or ammonia cleaning solutions. Chemically active cleaning solutions can damage the surface.
Do not use abrasive cleansers or solvents on airjet surfaces. Abrasive cleaners and solvents can damage the airjet surface.

Maintaining the Airjets
