Although it is the active
ingredient in at least one toilet bowl cleaning
tablet,
Trisodium Phosphate
is generally not good for
cleaning bathrooms, because
it will corrode metal.
Trisodium Phosphate may be
used with
Chlorine
Bleach
to remove
mildew
from wood.
Trisodium Phosphate
alone can
cause dark stains on
redwood
and Chlorine Bleach prevents it.
