If you live in a hard water area, make certain that the holes in the toilet rim are kept clean to ensure proper bowl flushing.
Toilet bowl cleaners should be used at least once a week. Use a long-handled brush to clean the rim holes, and to
clean as far into the trap as possible to prevent mineral deposits from forming.
Most toilet bowl cleaners are not harmful to the vitreous china surface of the toilet bowl. Please follow the bowl cleaner
manufacturers instructions carefully.
Do not use abrasive cleaners or solvents.

Do not use in-tank cleaners. Products containing chlorine (calcium hypochlorite) can seriously damage fittings in the
