Care and Cleaning
For best results, keep the following in mind when caring for your product:
• 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.
•
Wipe surfaces clean and rinse completely with water immediately after cleaner
application. Rinse and dry any overspray that lands on nearby surfaces.
• Do not allow cleaners to sit or soak on the surface.
• Use a soft, dampened sponge or cloth. Never use an abrasive material such
as a brush or scouring pad to clean surfaces.
• Be careful not to leave staining materials in contact with the surface for
extended periods of time.
• The ideal cleaning technique is to rinse thoroughly and blot dry any water
from the surface after each use.
WARNING: Risk of property or product damage. Do not use in-tank
cleaners in your toilet. Products containing chlorine (calcium hypochlorite)
can seriously damage ings in the tank. This damage can cause leakage
and property damage.
