“Using this to clean my night guard, it seems pretty simple to use. Used the tablets the first time. It got my night guard mostly clean, I do have some stains on it for a medication that may take some time to soak out. I also tried it on some pure gold jeweley and it sparkles not. I dump the warm water out each time and clean the stainless steel interior. So far I am pretty happy with this product. A dentist assistant recommended this product to me.”
