iSonic CSDW01 Denture and Retainer Cleaning Crystals for Dental and Sleep Apnea Appliances, 8 oz Bottle

This is my third bottle of the iSonic cleaning crystals and I use with the iSonic F3900. This is my first time purchasing directly from iSonic with delivery through Walmart Plus. I had on subscribe and save with another company but was notified it was no longer part of their program. Luckily found on Walmart's site and I'm a Walmart Plus member so worked out I could get for basically the same price minus the discount I received before but delivery was free and I was getting the real item through the manufacturing. I use this with my bottom partial and upper dentures and also with my husband's partial. It does a great job with taking out the stains from our drinking coffee and makes them look just as good as when we first got them. I usually do twice a week for mine and only once a week with my husband so the bottle last a long time for us. I would recommend to anyone looking for a good solution for keeping their dentures or partials cleaned. We've had no problem with the product.
