Can a toilet brush be washed in the dishwasher without risks?
and the bristles trap dirt that cycles can’t remove. The brush’s shape also prevents thorough cleaning.
Cross-Contamination Risks
Placing a toilet brush with utensils risks spreading harmful bacteria to items that touch food, raising the chance of illness.
Damage Concerns
Brush bristles can bend or detach, while hard parts may scratch the dishwasher, causing costly damage.
Better Cleaning Methods
Bleach soak: Soak in hot water with one cup bleach for an hour, rinse, and air dry.
Hydrogen peroxide: Apply directly to bristles for 10 minutes, rinse, and dry.
Vinegar + baking soda: Sprinkle baking soda, add vinegar, let fizz 15 minutes, rinse, and dry.
Maintenance
Rinse after use, store in a ventilated holder, disinfect regularly, and replace every 6–12 months or sooner if bristles fray, odors develop, or mold appears.
Bottom Line
Skip the dishwasher—use disinfectants and timely replacement for a cleaner, safer bathroom.
