CLR, 5 Pack, Fresh & Clean Garbage Disposal Foaming Cleaner. Each bag comes with 5 pods that quickly dissolve and begin foaming, filling every part of your garbage disposal with our specially formulated cleaner that cuts through odor causing residue and leaves your sink and disposal smelling fresh. For best results run the disposal until the foaming cleaner has risen out of the drain and retreated back into the kitchen sink disposal. This will ensure that the cleaner has reached every part of the food disposal. CLR has been a trusted household cleaner for over 30-years with a whole line of house cleaning supplies that help remove stains, buildup and grime from every part of your home.
