- —ifOil or sweat on your hands – if you leave it on for too long, your hands will sweat, making the drill bit surface slippery;
- Dust and lint in the air —especially noticeable for cat owners or people living in air-conditioned rooms;

II. The most practical method for cleaning drill bits
The following methods are based on actual user experience and combined with highly regarded practices found on ranking pages. I have also added some personal tips from my own experience to help you quickly determine which method is best for you.
1. Gentle washing with soapy water (safest and most universal)
If you are worried about damaging the drill bit, this method is 100% safe and can be used with both resin drills and acrylic drills.
How to do it:
- Prepare a bowl of warm water (not too hot).
- Add 2–3 drops of mild dish soap.
- Soak the drill bit in the tea strainer and shake gently.
- After scooping them out, rinse them thoroughly with clean water.
- Lay it flat on a paper towel and let it air dry.
Tip: Do not use a hairdryer, as the hot air may deform some of the drill bits.
2. Quick wiping method with wet wipes (suitable for light stains)
This method is especially suitable for people who are in a hurry.
Simply rub the drill bit on a baby wipe for a few seconds to remove oil stains. Let it air dry before use. While it can’t deep clean, it’s very quick at removing light oil stains.
3. Cornstarch dry washing method (powerful oil absorption)
If the drill bit feels “slippery,” it means it’s covered in grease, and cornstarch works particularly well in this case.
step:
- Pour a small amount of cornstarch into a small bowl;
- Add the drill bit and shake for 10–20 seconds;
- sieve.Shake off the powder using a sieve;
- Rinse with clean water if necessary.
