Evaporust has worked well for me. For more heavily rusted spots, remove after a few hours and lightly scrub (nylon brush, sponge, or similar) and then put back in a few more hours. I found on one pitted area it left a black coating that still had rust underneath when scrubbed off. For that I used several Naval Jelly (phosphoric acid) applications until the rust was no longer noticeable. Haven’t seen any impact to bronze or silver brazing. Didn’t have any paint impact on red Imron (82 Trek) or white (72 Fuji). Chrome came out looking great. Others have mentioned but if you’re partially submerged chrome it may rust MORE right above the vapor/liquid interface for Evaporust. Simichrome and a cloth took the very light surface rust off chrome for me (what came from the soak at the interface).
