Review on 🧻 Vanish Drop In Discs (1 Pack of 3) by Ronald Corcoran

We are two medical students and have almost no time to clean. They have worked VERY well for us. We have just moved into a new rental property and the previous tenants obviously did not clean the toilets regularly. In fact, they were downright repulsive. A ring formed around the waterline. I did the experiment on a toilet and didn't use any other cleaning products. We threw these puppies in a pond and within the first week parts of the ring began to disintegrate and fall off. After two months of regular use and washing, the ring has almost completely disappeared. They certainly do their job of preventing water build-up. The water is a pretty deep blue that I can take or leave. That way I at least have an idea that it's working and when I need to replace it. Our daily used/heavy traffic toilet lasted just under 2 months in a family of 3. The only complaint I have is the smell. No problems most days, but medium chemical smell every few days. This usually resolves after a flush or two. We become regular customers.
