CARE AND CLEANING
Use a detergent or non-abrasive toilet cleaner and a soft bristled
plastic brush to clean your toilet. To remove hard water stains, use
vinegar or lime dissolving cleaner and a non-scratch scour pad
made for porcelain. Allow a little contact time to allow the cleaner
to dissolve the buildup.
Do not spray cleaner directly onto the button, instead wipe it using
a dampened soft cloth with diluted dishwashing detergent and
dry it with another soft cloth. Do not use bleach or products that
include acid or alkaline detergents in their ingredients. Do not use
metal scrub brushes or steel wool.
NOTICE
DO NOT USE IN-TANK BOWL CLEANERS.
The use of high concentration of chlorine or chlorine-related products can
seriously damage fittings in the tank. This damage can cause leakage and
property damage. TOTO shall not be responsible or liable for any tank fitting
failure or damage caused by the use of in-tank bowl cleaners.
