Ask HN: Are there readily available chemicals that will break down proteins, that would work on prions? How do our digestive systems do it?

Anything that you think of as 'corrosive' will generally break down proteins. Strong bases or acids.

Unfortunately they also tend to break down living tissue too.

Relevant XKCD: https://xkcd.com/1217/
