although this isn’t strictly a jewelry question googling has yielded
no answer, so perhaps someone in orchidland might have the
appropriate solution: the other day i inadvertantly left a set of
cast aluminum salad servers in the dishwasher over night. this
resulted in unappealing grey brown droplet staining on one side, and
a greyish wash on the reverse. i have tried everything in my
jeweler’s arsenal to clean it off & restore the beautiful clean
surface. does anyone know what will help save these items?
Fill a pan with water to cover the aluminum servers, add 1
tablespoon cream of tartar or 1 tablespoon lemon juice per quart of
water, and simmer until the discoloration is gone.
