Revive an Oxygen stone?

[ddc]

Has anyone successfully resuscitated their old oxygen stone? I have a .5 micron stone on a stainless wand that is about a year old and despite my best efforts to keep it in good shape, it's not allowing air to pass anymore.

I boil it both before and after use as well as run more O2 through it when finished. I've never touched the stone and store it in a small ziploc bag. Any tips on restoration would be appreciated.

Thanks,
Dave

you need to soak it in acid. citric acid, phosphoric acid, lactic acid or even vinegar (acetic acid).

Thanks, I soaked it overnight in vinegar as you suggested and that worked great. Cheers!
