  1. 1

    Run hot water through your drain periodically. This will help to clear everyday build-up from the inside of your pipes.

  2. 2

    Pour 3/4 cup of baking soda into the sink drain. Pour 1/2 cup of vinegar into the drain and immediately plug the hole with a rag. Combining baking soda and vinegar causes a chemical reaction that will clean the PVC pipes. Let set for about 30 minutes before rinsing the drain with hot water.

  3. 3

    Consider using a chemical drain cleaner for tougher build-ups. Purchase a cleaner that is safe for use on PVC pipes. Follow the manufacturer's instructions for applying the chemical cleaner to the drain.

  4. 4

    Pour lemon juice into your drain to help loosen toothpaste build-up and any odours.

  5. 5

    Insert a plumber's snake into the drain to clean large clogs or build-ups. Run the snake in and out several times to clean the inside of the PVC pipe. Flush with hot water when done.

  6. 6

    Call in a professional plumber for stubborn clogs that you cannot clear.
