Toilet brushes are made of materials that may not withstand the dishwasher’s environment. The heat and intense water pressure could deform the brush or damage the appliance’s internal components.
Alternative Cleaning Methods
1. Bleach solution:
One of the most effective ways to disinfect a toilet brush is to soak it in a bleach solution (1 part bleach to 6 parts water) for an hour, then rinse thoroughly and let it dry completely.
2. Hydrogen peroxide:
Hydrogen peroxide is a household disinfectant that can be used similarly to bleach. Soak the brush and then rinse well.
3. Vinegar and baking soda:
For a more natural approach, soaking the brush in a mixture of vinegar and baking soda can help disinfect and remove odors. This should be followed by a thorough rinse.
Guidelines for Toilet Brush Care
1. After each use, allow the toilet brush to dry completely before placing it back in its holder.
2. Clean and disinfect the toilet brush regularly using the alternative methods mentioned above.
3. Replace your toilet brush at regular intervals or if it shows signs of wear and tear.

Conclusion
While placing a toilet brush in the dishwasher may seem like a convenient shortcut to cleanliness, it is not advisable due to the risks of cross-contamination and the potential damage to both the brush and the appliance. Instead, opt for safer, more effective cleaning methods that ensure the hygiene of your bathroom without compromising the cleanliness of your kitchenware. Always prioritize the health and safety of your household by following best practices for sanitation and maintenance.
