How to get rid of mould on an electric toothbrush

Updated February 21, 2017

Sometimes the charging base on an electric toothbrush head gets mouldy after long periods of use without cleaning. Mould can be toxic, and should be removed immediately. Frequent cleaning of the toothbrush base is vitally important to keep mould and mildew at bay. Always replace the head of the toothbrush if mould is present. Replace the toothbrush head regularly at three-month intervals.

  1. Mix one part chlorine bleach with 10 parts water.

  2. Remove the head from the base of the toothbrush.

  3. Dip the cleaning toothbrush into the bleach solution.

  4. Scrub the base of the toothbrush all around the outside until no mould remains. Follow up with clean, hot water and wipe down.

  5. Unscrew the nut from the top of the base and clean inside with the cleaning toothbrush and bleach solution.

  6. Dip the cloth in the bleach solution. Scrub down the charging base of the electric toothbrush.

  7. Tip

    Frequent cleaning of the toothbrush using a disinfecting wipe in the same manner described above will keep your electric toothbrush free of mould. Clean the toothbrush at the same time you clean the bathroom.


    Bleach is a caustic liquid, so wear rubber gloves when cleaning with it. Throw away or clean thoroughly any items used in the bleach solution. Failure to do so, or ingesting this liquid can cause serious injury.

    Make sure the cloth is purely white or something you do not care about, because the bleach will discolour it.
