Has anyone tried putting polident or some other retainer/denture cleaner inside their bottles while there soaking? I'm thinking of trying it but am wondering if anyone has a reason for me not to.
There is a product called Formula...something you can find it at I guess what you would have called head shops back in the 70's. it is made to clean smoke residue etc out of glass pipes. We find it works even on scale and stains etc. We tried this after even muriatic acid couldn't get the stuff off, we are using vintage ketchup bottles for bath oils and homemade bubble bath and they have not only gotta be clean but sterile as well.
