Studies consistently rank the toothbrush holder as one of the most germ-contaminated surfaces in the home — more so than most toilet surfaces. The standing water and damp toothbrush handles create ideal conditions for mould, yeast, and bacteria to thrive inside the holder's holes. Weekly cleaning is worth making a habit.
Dishwasher Method (Easiest)
- Check if your toothbrush holder is dishwasher safe (most ceramic and stainless steel ones are; most plastic ones are top-rack safe)
- Remove it from the bathroom and place in the dishwasher
- Run a normal cycle
- Allow to dry completely before returning it to the bathroom counter
Hand Wash Method
- Remove all toothbrushes
- Fill the holder with hot water and a few drops of dish soap — let it soak for 5 minutes
- Use a small bottle brush, pipe cleaner, or old toothbrush to scrub inside each hole thoroughly
- Rinse well
- Disinfect: fill with diluted white vinegar (or a diluted bleach solution for heavy mould) and let sit 10 minutes, then rinse completely
- Allow to air dry upside down before replacing toothbrushes
Tips
- Clean weekly — the slime that develops inside the holes in just a few days is primarily bacteria and yeast
- Store toothbrushes upright and uncovered — covered holders trap moisture and accelerate bacterial growth
- Replace toothbrush holders that have cracks or pitting in the holes — these harbour bacteria that can't be fully cleaned
- Wall-mounted holders with open bases allow better drainage than solid counter holders and are easier to keep clean
