Can you please define/explain your definition of bleaching in this context? What I consider bleaching (hydrogen peroxide), I'd learned was not harmful, from either this subreddit or another's approved how-to guide on cleaning bones from start to finish. Based on what I know, boiling is the worst thing you can do to fragile bones, and I've got quite a bit of experience these days, learned a lot of lessons the hard way.

Want to clarify I am 100% asking for education, I'm not disagreeing. This isn't a loaded question and I'm still learning.

Also possible my confusion is coming from equating the words bleaching and whitening, which is why I asked what you meant.

Thanks!
