Soft Scrub Duo-Cubes In-Tank Automatic Toilet Cleaner with a refreshing Alpine Fresh scent delivers continuous cleaning, flush after flush. Formulated with Anti-Clogging Technology* to help dissolve toilet paper residue over time (*not a clog remover). It helps fight toilet ring, hard water, and limescale stains. Safe for septic tanks and toilet components, this automatic toilet cleaner helps clean and freshen from tank to drain. Each cube lasts up to 4 weeks to help keep your toilet clean and fresh between regular cleanings. For best results, clean the toilet bowl thoroughly. Take one cube. Do not remove the protective wrap on the cube (it is water soluble). Remove the lid from the toilet tank and flush. When water is low, drop the cube in the tank near the side wall away from water valve opening on bottom. Wait 10 minutes before flushing again. Store remaining cube(s) out of reach of children and pets. Note: Once the water is no longer blue, the cube is gone.
