75C for 30 minutes for N95 Masks
I copied the below from the Washington post. Check out the article. They are not the only ones to say this. It is pretty much the consensus of the scientific community. Soap is as good as you can get;
Soap — bar soap, liquid soap, laundry detergent and such — is virus kryptonite, which is why the message “Wash your hands!” is everywhere. But Menachery said heat and ultraviolet light are two other ways to neutralize a coronavirus, and each of these methods works in a different way.
One thing I find missing here is that one the best and cheapest disinfectant for COVID-19 is actually plain old soap and water. I can’t remember at the moment where I found the articles but there are several out there on the internet by reputable virus scientists. The thing about these coronaviruses is their protective shells are made of an oily substance which is highly vulnerable to plain old soap and water. Hense the main point of washing your hands during this COVID outbreak is the washing part. The rinsing part is somewhat redundant if you have washed properly with soap. We use chemicals much of the time but we have become rather religious about wiping down many things around the house with soap and water. And often some of the packages we get as well. Not so special for cardboard but it works great on plastic that we feel we need to open without waiting. Vegetables from the grocer being one.
An item I am uncertain about is the claim by WebMD of five days quarantine. We have been using that as our standard, but I have as yet been unable to find verification or the source of their claim. So far it seems to be a random number.
