How to clean an electric toothbrush? It’s a question more important than most realize. A toothbrush may keep your teeth healthy, but without proper cleaning, it can quickly become a breeding ground for bacteria. In this guide, we’ll cover daily and weekly cleaning routines, the mistakes you must avoid, and how BrushO’s smart design—IPX7 waterproofing, anti-splash technology, and Qi wireless charging—makes toothbrush hygiene effortless.

Oral hygiene isn’t just about brushing—it’s also about maintaining the tools you rely on.
These mistakes often cause more harm than good—especially for waterproof smart toothbrushes.
BrushO is designed to simplify toothbrush hygiene:
Fully safe to rinse under running water, reducing bacterial buildup risk.
Keeps toothpaste residue to a minimum, making cleaning faster.
No exposed metal ports = fewer hygiene issues, no corrosion risk.
Swap out every 3 months without worrying about stock—each box comes with four.
👉 With BrushO, cleaning is less of a chore and more of a quick routine.
Q1: Can I clean my electric toothbrush with mouthwash?
Yes. Soaking the brush head in mouthwash helps kill bacteria.
Q2: How often should I deep clean the handle?
Once a week is recommended, or more often if residue builds up.
Q3: Is BrushO safe to rinse under water?
Yes. Thanks to its IPX7 waterproof rating, it can be rinsed safely.
Q4: Do I need to clean if I replace brush heads regularly?
Yes. Handles and charging bases still require cleaning.
Keeping your electric toothbrush clean is as essential as brushing itself. With the right care, you extend the life of your device, protect your oral health, and avoid costly replacements.
