Hi everyone,
Does anyone have a simple solution for removing rust stains from glassware?
I have not had much luck with oxalic acid and usually resort to steel wool and Bon Ami or similar. There must be an easier way.
Thanks,

Rust stains on Glassware
HI Gwen,
I am currently cleaning up my test tubes, I also use 3m HCl and leave them overnight. This solutions works for several applications, just pour it our into a beaker and then refill your next load of test tubes.
Good luck

Re: Rust Stains on Glassware
Hi,
I have a bunch of rusty test tubes that have been soaking in napisan for days (some more than a week). Most of them have come clean but there are a few very stubbourn ones. Now I don't have any Oxalyic acid what else could I use to clean these up? someone mentioned 3M HCL will this work?

I haven't mixed them together. Just use approx 2m HCl. Does the trick overnight. Someone else might know though.

Re: Rust Stains on Glassware
10% Oxalic acid is fairly good at eliminating most glassware stains and such. Most.
I've also attempted lifting stuborn iron oxide using warm 5M HCl with some success. Some.
Howvever, I still have stained glassware that nothing seems to clean. Nothing. Very stubborn. Most annoying.
