Did you ever think your denture tablets had more uses than one? Turns out, denture tablets contain many of the same ingredients as basic household cleaners and laundry detergents: Potassium Persulfate (oxidizer), Sodium Perborate (peroxide-based bleach), Sodium Bicarbonate (baking soda), Sodium Sulfate (salt), Sodium Carbonate (soda ash), Pentasodium Triphosphate (hydrogen peroxide stabilizer), Sodium Lauryl Sulfoacetate (surfactant), Magnesium Stearate (stabilizer), Tetrasodium EDTA (chelating agent).

Developed to clean porcelain and acrylic resin dentures, they can be used to clean similar household surfaces. Learn some ways to use denture tablets as you clean around the house.

Before You Begin

Dropping in a premeasured tablet is easy and can work in a pinch, but you should also consider the cost per use. An all-purpose household cleaner is often more cost-efficient. Always consult the manufacturer's cleaning guidelines before using a denture tablet on porous surfaces, uncoated metals, or fabrics since it contains bleaching agents.

How Often to Use Denture Tablets

Used correctly, you can use denture tablets as often as you'd like to clean certain surfaces like china, porcelain bathroom fixtures, glass and ceramic bakeware, and most glass or metal small appliance interiors.
