Anyone have a good technique for removing old fossilized rubber door gaskets? The American Dental Accessories removal tool seems worthless to me; I've destroyed a lab knife and cut up my fingers. Is there some magic gasket sauce? Help!!

Can you soften the rubber with your Hanau alcohol torch, then scrape it away using a razor blade? Would an adhesive remover (such as Goo-Gone) help soften any thin pieces left over? If you call your supply house, what do they advise?

I finally got it out by ditching the inner edge of the gasket with a 557 fg. There's black dust all over the operatory. I think that's enough material to write a song...

I've used them for years, and they never fail a spore test. I took a chance and bought this one on ebay. There was a short in the wiring that I fixed, and then I noticed it leaked before pressure was reached. It's going to be my backup.

We try to change the gaskets once a year as a preventative measure. I can understand the reluctance to invest lots of money into a used machine until you know for sure that it works well. Personally, I prefer the electronic autoclaves that vent and shut off by themselves. I have never been able to get staff to be consistent at rotating dials on a manual autoclave, therefore, one cycle would end up running for 5-6 hours instead of 45 minutes. I figure the savings in electricity (and stress) pay for the machine. Every 18-24 months, the electronic autoclaves seem to require some service though. I have an old OCM in the back room for use when the big modern one is out for service. Some office manage to hire staff people who actually pay attention to the autoclave and spin the dial at the right times. I never was so lucky.

I never was so lucky. The Castle has a mechanical timer--shuts off after 30 minutes. You do have to remember to vent though.

That is better than the P-C that you have to rotate the dial to fill, to start the cycle, the stop the cycle and to begin venting, then open the door physically. There were days when the ladies would only run one cycle for the entire day--one 6 hour cycle. Signature/ Amatus / >>>I took a chance and bought this one on ebay.

And warm the autoclave up a little first. carabelli >> Anyone have a good technique for removing old fossilized rubber door >> gaskets?
