<HTML>Several weeks ago, I believe it was Roger Jolley, who told us about how great Tarn-x is. So I bought a bottle, to brighten up the brass parts on my Baldwin. I'm glad I read the instructions first. The very first paragraph on the back of the bottle says: "Important:, Do not use on stainless steel, chrome, pewter, aluminum, brass, artificially oxidized silver, lacquered surfaces, pearls and porous stones. Avoid spilling on laminates, counter tops, Formica or synthetic surfaces." And, oh, yea, WEAR PROTECTIVE GLOVES. AVOID CONTACT WITH SKIN AND EYES. In case of contact, flush immediately and thoroughly wash with water for 15 minutes. Call a doctor or poison control center for more advice Great stuff. Too bad I can't, and don't want to, use it.
