Dyes used to encapsulate the
cleaning particles in scouring powders or other colored cleansers
can get into the crevices of such worn surfaces, and if not rinsed
off, and allowed to stay and harden for days, can be almost impossible
to remove. A strong chlorine bleach solution may lighten the
stain, but will also further dull or discolor the porcelain surface.
So one may have to live with the stain.
Removing Rust/Iron Stains
on Bathroom Fixtures:
Rust stains come from iron in
the water supply, which can only be permanently remove through
installation of an iron filter. Occasionally iron is dissolved
from rusting water pipes or mains by corrosive water. Iron stains
can be removed by a weak acid solution, usually oxalic acid which
is highly toxic and must be handled with care. Never use chlorine
bleach as this sets the iron stain.
Fresh iron stains on plumbing
fixtures such as sinks, bathtubs and chrome will generally yield
to treatment with heavy duty cleaning compounds containing large
proportions of trisodium phosphate. Apply cleaner with damp cloth,
pad or sponge. Rub discolored surface until stain is removed.
Rinse. Wipe dry and polish.
Heavy, stubborn rust stains
can often be removed by oxalic acid stain remover compounds such
as Zud or a tri-chloro-melanine compound such as Barkeepers Friend.
Follow directions carefully.
For rust stains already set
on bathroom or kitchen plumbing fixtures, dissolve oxalic acid
crystals in hot water and add enough whiting or talc to make
a soft paste. Apply this poultice to stain and let dry before
removing. Rinse and polish.Use with care-it is poisonous.
