Total Care of Sinks, Plugholes and Overflows

  • Foam expands to fill the pipe to prevent the build-up of debris
  • For use in all plugholes, pipes & overflows
  • Use weekly in the kitchen & bathrooms

From preparing food to washing the dog or dirty trainers, a lot of debris ends up being washed down the plugholes which builds-up over time leading to that dreaded blockage. Plugholes and pipes are notoriously hard to clean and a glug of bleach just won’t reach all areas of the pipe and overflow needed to maintain and keep your pipes flowing freely.

How to use

To deep clean plugholes and overflows

  • Step 1.

    Simply squirt into plughole or overflow until foam fills the pipe. Also use around the sink, bath or shower surfaces
  • Step 2.

    Leave to work for 30 minutes
  • Step 3.

    Flush with hot water
