It was probably discussed previously and I had read a bit about it but still would like to ask.
Many people suggest never use chloride bleach as it will eventually destroy the skull over the time. I had previously used H2O2 for that purpose several times but it takes a lot of time, you need a lot of H2O2 and as such it cost some money. Chloride bleach at the other hand is very cheap and do the job much faster.
Friend of mine once used chloride for that and the skull seems OK for several years now.
I personally think if you wash out bleach very well after using it then it should be OK.
One downside of chloride bleach for that purpose is that the skull becomes unnaturally white, while when using H2O2 it remains more naturally colored, like ivory.
Any shared experience or suggestions would be highly appreciated.
Thank you!
