Cleaning Vitreous China Toilet Bowls


Toilet bowls are made of vitreous china, a very hard
and acid-resistant material. Commercial toilet bowl
cleaners contain very strong acids which remove hard
water and iron deposits, clean and disinfect. They are
too strong to be used on other surfaces. They are also
highly toxic so use carefully, following product label
directions, and NEVER mix any other products with the
bowl cleaner! Never use products designed for drains as
they will eat into the pipes.

Chlorine bleach may be used alone, never combined
with bowl cleaner or any other product. Add 1/4 cup to
the toilet bowl, let stand few minutes, brush around edge
of bowl and flush. This whitens and disinfects.
