Would there be any point in swabbing/gargling with Hydrogen peroxide after going

into a high risk situation?

Definitely, first line of defense is social distancing and hand-washing hygiene, but if you have a high risk encounter, do you think you could swab your nostrils and gargle with with hydrogen peroxide, or a mouthwash containing alcohol?

Or is it too late? Is exposure almost simultaneous with infection? Or is there a short grace period where you can get the virus off your mucus membranes?

I'm guessing you couldn't really do much about your eyes, except maybe use an eye wash?

1. It is a good idea to use peroxide to flush out your ear canal as well

2. Covering face, boiling water, or tea

Would be nearly as effective

7. It's marginal, but masks helped slow the spread in 1918

You should not be allowed in a public space (like a grocery store) without some form of cover.

The data seems all over the the place about heat. I have heard everything from 77F to 70C to kill the virus.

6. I might remind you that H2O2 is a potent emetic (vomiting inducer)

Gargling with warm salt water, listerine, or baking soda solution might be more reasonable.

If you want to go with hydrogen peroxide, dilute to a 3% solution (2 parts water to one part food grade 12% H2O2)

8. Hydrogen peroxide can be deadly

Hundreds of people have become severely ill and at least five have died after consuming high-concentration hydrogen peroxide that some people take as an additive to their diets, according to a new study.

There was a tragic case some years ago in Arizona where someone mistook a container with hydrogen peroxide for water. It killed him.

I think mouthwash is better since it tastes noticeably bad/strong.
