  • Hot water

  • Dishwasher

  • Dishwashing detergent

  • Old comb

Hanging from a hook near your bathtub lies your once favorite bath brush. It sits crusted with bathroom mold, soap scum and other unidentifiable dirt. You'd love to clean this brush to use when enjoying bath time but you don't know how. Cleaning a bath brush requires very little effort to make even the nastiest bath brush usable once again.

Ammonia and Shampoo

Step 1

Slide an old comb between the bristles of the bath brush to remove any hair and loose dirt. Rinse the comb frequently so you don't embed more dirt in the bristles of the brush.

Step 2

Boil water in a pot on the stove. Move the pot to the kitchen sink and pour 1/2 cup ammonia into the water. Add one capful of shampoo to the water.

Step 3

Place the bath brush into this mixture and stir the brush head through the water to help loosen the filth on the brush. Allow the brush to soak for at least 15 minutes.

Step 4

Run warm water over the brush to remove grime that has worked free of the bristles. Place the brush back into the solution to free any remaining residue.

Step 5

Rinse thoroughly with cool water and allow to dry before use.

Baking Soda, Vinegar and Hot Water

Step 1

Fill your bathroom or kitchen sink half full with the hottest tap water possible.

Step 2

Add 1/2 cup baking soda and 1/2 cup white vinegar to the water. Both are all-natural cleansers and disinfectants that won't harm the bristles of the bath brush.

Step 3

Immerse the bath brush into the water and allow it to soak for 15 minutes. Stir the brush around in the solution to work dirt free from the brush.

Step 4

Check the progress by rinsing the brush in another sink under clear running water. Resubmerge the bath brush if necessary into the vinegar and baking soda solution to remove stubborn grime and rinse with clear water.


Step 1

Use a wide-toothed comb to remove any hair, loose mold or soap residue from the bath brush.

Step 2

Place the brush bristle-side down on the top rack of the empty dishwasher. You might want to include hairbrushes and combs as well to prevent wasting the entire cycle of the dishwasher. Use a dishwasher basket for small bath brushes to prevent the item falling and hitting the heating element of the dishwasher.

Step 3

Add dishwasher detergent and run the dishwasher on an abbreviated cycle to clean and disinfect the bath brush.
