How to Clean Toilet Brush and Holder

Your toilet brush cleans the bowl — but who cleans the brush? A dirty toilet brush and holder can harbor bacteria, mold, and foul odors, and reintroduce contamination every time you use it. Regular cleaning of both the brush and holder is an essential part of bathroom hygiene.

Why You Need to Clean Your Toilet Brush

• Bacteria from the bowl cling to the bristles after every use
• Moisture trapped in the holder creates ideal conditions for mold growth
• A dirty brush spreads bacteria rather than removing it
• Foul odors from the brush holder contaminate the bathroom air

What You'll Need

• White vinegar
• Baking soda
• Bleach (optional, for deep disinfection)
• Rubber gloves
• Spray bottle
• Old towels or paper towels

Recommended: white vinegar, baking soda, Clorox Clean-Up with Bleach, rubber gloves, and a spray bottle. If your brush is worn out, consider upgrading to the AONEZ Compact Toilet Brush & Holder with drip-proof design.

Method 1: Vinegar Rinse (After Every Use)

1. After cleaning the bowl, hold the brush over the toilet bowl.
2. Pour white vinegar over the bristles to rinse away debris and disinfect.
3. Let the brush drip-dry by resting it across the toilet bowl rim with the lid closed on the handle — this allows air circulation before returning it to the holder.
4. Once dry, return to the holder.

This quick rinse after every use dramatically reduces bacterial buildup between deep cleans.

Method 2: Vinegar Soak (Weekly Deep Clean)

1. Put on rubber gloves.
2. Fill the brush holder with undiluted white vinegar.
3. Place the brush in the holder so the bristles are submerged in vinegar.
4. Let it soak for 1 hour.
5. Remove the brush and rinse under hot water.
6. Empty the holder, rinse it thoroughly, and dry both before reassembling.

Method 3: Bleach Disinfection (Monthly Deep Clean)

1. Put on rubber gloves.
2. Fill a bucket with 1 gallon of water and add ¼ cup of bleach.
3. Submerge the brush bristles in the bleach solution.
4. Let soak for 10–15 minutes.
5. Rinse thoroughly under hot running water.
6. Allow to air dry completely before returning to the holder.

Alternatively, spray the bristles with Clorox Clean-Up with Bleach, let sit for 5 minutes, then rinse.

How to Clean the Toilet Brush Holder

1. Empty any liquid from the holder.
2. Spray the inside and outside with white vinegar or bleach solution.
3. Let it soak for 10 minutes.
4. Scrub the inside with a small brush or old toothbrush.
5. Rinse thoroughly and dry completely before replacing the brush.

Important: Never return a wet brush to a wet holder — this creates the perfect environment for mold. Always allow both to dry completely.

How to Dry the Toilet Brush Properly

1. After rinsing, rest the brush handle across the toilet bowl rim with the lid closed on top of the handle.
2. The bristles hang over the bowl, allowing water to drip in and air to circulate.
3. Leave for 10–15 minutes until the bristles are no longer dripping.
4. Return to the dry holder.

How Often Should You Clean the Toilet Brush?

• Vinegar rinse: after every use
• Vinegar soak: weekly
• Bleach disinfection: monthly
• Replace the brush: every 6 months, or when bristles are splayed or discolored

Frequently Asked Questions

How do I know when to replace my toilet brush?

Replace when bristles are splayed, discolored, or no longer spring back to shape. A worn brush is less effective and harder to clean. Most brushes should be replaced every 6 months.

Can I put a toilet brush in the dishwasher?

Not recommended — the high heat can warp plastic handles and spread bacteria to your dishwasher. Hand cleaning with vinegar or bleach is safer and more effective.

Why does my toilet brush holder smell so bad?

The holder collects dirty water from the brush after each use. This stagnant water breeds bacteria and mold rapidly. Rinsing the brush with vinegar before returning it, and cleaning the holder weekly, eliminates the odor.

Is there a toilet brush that's easier to keep clean?

Yes — drip-proof holders like the AONEZ Compact Toilet Brush & Holder are designed to minimize water pooling and are easier to clean and dry than traditional open holders.

Final Thoughts

A clean toilet brush is a non-negotiable part of bathroom hygiene. A quick vinegar rinse after every use, a weekly soak, and a monthly bleach disinfection keep your brush effective and odor-free. Always dry both the brush and holder completely before reassembling — moisture is the enemy. And when the bristles are past their prime, replace the brush — a fresh brush cleans far better than a worn one.
