pull it out with a liquid chemical mixed with a
powdered poultice. When placed on the stain, the
chemical dissolves it, and the powder absorbs it.
The list on the left shows the chemicals that work
best with common household stains.
poultice is readily made available and sold where
ever stone and tile are sold. Look for the kind that
are Iron free and haven't been premixed with stain
removing chemicals. Before applying a poultice, always
clean a stain first with water and pH-neutral stone
soap, such as Aqua Mix's Stone Cleaner or Stone Care
International's Marbamist. Blot, don't wipe the area
dry; then wet it with a little distilled water. Then
follow the steps below
the appropriate stain removing chemical (see list on

Once it's bone dry, scrap it off, throw it away, and
rinse the area with distilled water.
stain is gone, let the stone dry and apply a sealer.
If any sign of the stain remains, repeat the
poultice process. If stain isn't gone after five
tries, call in a stone specialist.
