optimize titanium for welding and anodizing without hydrofluoric acid!. multi-etch® is a low-acid (ph 6.8) alternative to hydrofluoric acid and can be used on the following metals: more information on select metals is below. for metals not included here, ask us or send a sample and we’ll test it for you. anodized titanium unetched (top), and treated with multi-etch (bottom), anodized all at once. on titanium and niobium, i use multi-etch to remove anodizing mistakes and to clean off contamination—iron from rolling mills, minor heat single piece of titanium that i left “as is” on the top, cleaned with multi-etch on the bottom, and then anodized. it looks like i copper and bras* etch more quickly than titanium. you can use multi-etch to remove light firescale from silver but not from gold. you can clean iron contamination from platinum without removing any platinum ions. i’ve done limited testing with multi-etch on platinum for etch effects—that is, removal of platinum ions—and there doesn’t seem to be any effect. i have not tested it with rhodium plating but i as*ume there would be no effect on that either. although multi-etch will etch glas*, it does so too slowly to be practical for i have used multi-etch to remove broken steel drill bits trapped in titanium and gold. multi-etch will enhance the patterns in mokume and the crystals in meteorites by etching the different metals at different rates, thus here is some meteorite showing before and after treatment with multi-etch: although my experience is with jewelry, there are many other industries where muti-etch is used, such as the dental and medical just how safe is multi-etch compared to hydrofluoric or nitric acid? well, while i would never recommend this, i have reached my hand into 100°+ f heated multi-etch to retrieve a part and i suffered no ill effects (all ten digits and skin intact). you would suffer significant damage if you tried that with hydrofluoric or nitric acids.
