Just put one stick in the drain pipe every two weeks, and it will slowly dissolve deep inside the drain pipe, effectively eliminating the source of odors. One tablet lasts for approximately 10-15 days, thoroughly cleaning pipe dirt and odors! It works by gradually dissolving, so the effect lasts a long time. The effects of fumaric (organic) acid and disinfectant thoroughly clean and disinfect the slime and bacteria that cause odors in standing water.
