This is a product for preventing bad odors, bog moss and mildew in sink drains.Unlike conventional ball or powder products, this is designed to be locked into a drain. It does not give off an unpleasant odor because no chlorine gas is generated. It is also safe for use in kitchen fixtures such as sinks. The effects of a cartridge, which is filled with particles for cleaning and killing germs, continue for two months.
The cartridge needs to be replaced only when the particles are completely dissolved.
(Stains around the cartridge can be cleaned with dishwashing detergent.)
