Ok so I'm a very small lab with a handfull of small accounts that still take inpressions. To safeguard myself and staff I spray a 10% bleach solution into each bag then place impressions,bites, anything in bag into a 10% bleach solution. I cannot find any other disinfectant solution but I remember when HIV started to explode the bleach solution was recommended. Anyone else using this or another method they would recommend?

We used bleach solution back then. I can't remember if it was 7 or 10%+. We had a dunk tank (small cooler) and the impression and everything else that could be put in there from the case pan went in for 'X' time. I never contracted HIV, hep A,B,C or anything else when we used that method. Not proof it works, only anecdotal.

*edit
The tank was changed daily at a minimum since chlorine is unstable and breaks down quickly. Sometimes several times a day depending on the case load.

Yes, but the flash point of ethanol makes it somewhat risky. Chlorine kills everything as well.

I bought several jugs of denatured alcohol past night since it her products have been hoarded and are in short supply.
I bought a bottle of 28% clorhexidine and another 5 gal of 99.9% IPA, that will last for a very long time... looks like ppl were not aware and it was still on stock, ready made sanitizers were long gone

Any labs getting calls to donate PPE to the hospital or Health Dept? I have heard of Practice Owners getting these calls.

The 1 to 10 solution of bleach and water is the best disinfecting solution for our job but it has serious drawbacks. It attack chrome cobalt with a vengence. It is corrosive to other metals. It's fumes are hazardous to your lungs. The link was for the SARS outbreak but is still relevant today. https://www.info.gov.hk/info/sars/en/useofbleach.htm
