Hello all, New here. I have a quick question. I have been using
expired Crest Whitestrips (sept 2004) for a while now. Does the
Hydrogen Peroxide expire and no longer work? Is it just not as
effective as when it wasn't expired? If it is a useless cause I
think I will stop and forgo the annoyance.
Thanks!
John
