Care and Cleaning
For best results, keep the following in mind when caring for your KOHLER bath with airjets:
•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
If cleaning the airjets is necessary due to hard water deposits, wet a soft, non-abrasive cloth with
white vinegar and wipe the plugged airjet holes. Immediately rinse the area with clean water to
avoid long-term exposure of the vinegar to the airjet surface.
Fill the bath with water to the top row of airjets. Drain the bath and press the purge button.
Cleaning Your User Keypad and Remote Control
Use a soft cloth to wipe the keypad and remote control after each use. If the surface becomes dirty,
use a non-abrasive soap and warm water to clean.
