Want antitarnish treatment for bright dipped brass that is good to 200 C

Brass items once Etched in Acid Dip gets rid of all oxide layer & get gold shine but shine do not remain stable, Suggest me good antitarnish which is stable at high temperature 200 °C.

GM,
Try using Benzotriazole ⇦this on eBay or Amazon [affil links] in the final hot water dip in preventing the tarnishing after bright dip.

All the best.
