Toilet brushes play a key role in keeping bathrooms clean, but because they regularly come into contact with toilet surfaces, they can quickly become breeding grounds for bacteria and germs.
While using a dishwasher to clean them might seem like a simple solution, this method poses several risks that outweigh any convenience.
Why Dishwashers Aren’t Suitable for Toilet Brushes
Dishwashers are designed to clean kitchenware, not bathroom tools. The shape and material of toilet brushes make them difficult for dishwashers to clean thoroughly.
The high-pressure water jets and heat might not reach deep into the bristles, where bacteria can linger. Moreover, most dishwasher detergents aren’t formulated to kill the kinds of bacteria typically found on toilet brushes.

Cross-Contamination is a Major Risk
One of the biggest concerns is cross-contamination. Washing a toilet brush in the same appliance used for dishes and utensils risks spreading harmful microorganisms to the very items that come into contact with food and mouths. This could increase the chance of illness in your household.
