@livingsober4life: I’d say for a washing machine that needed that for years and just had it done. I did a pretty good job. We probably need to do it about four times for the first month and if you buy a new washing machine, I would highly recommend that you use these regularly from the beginning and that would probably solve all your problems so check it out guys great products if you wanna get rid of some dog hair and dog out are definitely check these out. ##laundryday##laundry##doghairremoval##doghair##washingmachinecleanertablet
