Chris,

Not dure why you used mineral spirits on a yellow stain? Yellow is usually
related to iron or rust and you need to apply iron out or rust aid to your
DE powder. Don't the iron out or rust aid is an acid and the stone will need
to be honed and polished. Also you could darken the stain, depending on what
is causing the stain.

The mineral spirits work good to remove oil stains, the darken you are
seeing is from the mineral spirits that have not totally dried out yet. if
you want to speed up the drying process then place plain DE powder on the
surface and the dry powder will pull the mineral spirits from the stone
quicker.

Subject: Poultice on marble

I applied a poultice of DE and mineral spirits to a Carrara honed floor. It
was some yellowish stains that I was trying to remove and 24 hours after
applying the poultice I removed the plastic and it looks as though the
poultice has darkens the stone around the area. I believe this will dry up
and disappear but I just want to know if anybody has some feedback on this.
