I spray colloidal silver after I shower and also rinse my mouth with it
After each shower I use colloidal silver in a spray bottle and while still damp I go over that with a Lafes mineral crystal.
It kills the bacteria that cause foul odor and lasts all day. Works well for me according to others.
Also, I gargle and brush with the colloidal silver to prevent bad breath using a flouride-free toothpaste.
