Drainer cleaning products will keep drains free from dirt and grime and water flowing whilst stopping blockages occurring. Our range of professional drain cleaner chemicals from leading brands such as Jangro and Diversey are designed for commercial use. Need to unblock your sink? Try our Jangro Sink & Drainer Cleaner, one of our most popular drain cleaners for daily sink and plug hole maintenance. For heavy duty blockages caustic soda may be the only option, so we stock a range of different sized bags suitable for the heaviest blockages too.
