Review on 🧼 SmartGuard Premium Cleaner Crystals: Eliminate Stains, Plaque & Bad Odor! Perfect for Dentures, Clear Braces, Mouth Guard, Night Guard & Retainers - 110 Cleanings! by Sheryl Stewart

This product is the only thing that has saved my sanity with my Invisalign aligners! Brushing my teeth and mouthguard twice a day was not enough to prevent the mouthguard from discoloring and tarnishing. That's probably because I drank everything with trays instead of taking them out for everything but water. I work with children and didn't want to put my hands in my mouth so often! Either way, these packs are great. I keep one in a small covered bowl by the bathroom sink and soak the trays each night over dinner or in the shower. Each pack lasts for 7-10 days! Costs money
