Stains from fruit on glass
I've just noticed stains from Bananas on two large fruit bowls. They were made from Spectrum "96" a doule thick clear base with an opal red and opal yellow design on top. The stain is on the opal surface and will not wash off with dish detergent. It is not a coloured stain just slight markings like you get if you let water dry on a surface without wiping. I figure it must have somthing to do with the fruit acids reacting with the opal glass surface. Any suggestions on cleaning off without damaging the high gloss finish? Thanks, Don.

hi brian, oxalic acid will work. it is sold in a crystal form as wood bleach over here. it is also the active ingrediant in zud tm cleanser. i use it to remove tannin stains from boat hulls. a mild solution of this will remove what would take a smoking concentration of muriatic to do the job. rosanna
it's also the main ingredient in barkeeper's friend, sold in the laundry soap dept of the grocery store. i use it to remove tannin marks from oak, along with removing hard water stains from glass shower doors or tile.rosanna gusler wrote:hi brian, oxalic acid will work. it is sold in a crystal form as wood bleach over here. it is also the active ingrediant in zud tm cleanser. i use it to remove tannin stains from boat hulls. a mild solution of this will remove what would take a smoking concentration of muriatic to do the job. rosanna
