Using a mixture of 1 part Alum spice to 2 parts water. It works quickest if you heat the solution up(I use my studio crock pot). After about 30 minutes the drill bit should be completely gone! Alum is a spice commonly found in grocery stores. The great thing about using alum is that it is natural and safe. Something you can use to spice up your food as well as create jewelry? That's a no brainer to me.
You need to much more specific about your alum claim. The alum will actually destroys stainless steel when trying to get rid of the drill bit.
ReplyDeleteThanks for your reply! Yes, unfortunately it does destroy stainless steel (hence the dissolved drill bit), so alum isn't good for stainless steel jewelry.
