What Not to Put in an Ultrasonic Cleaner
If you're wondering what not to put in an ultrasonic cleaner, the answer is anything sensitive to heat, vibration, or moisture. These devices are powerful, and while perfect for ultrasonic cleaner dental equipment, they can damage delicate or incompatible items.
- Gemstones (e.g. emeralds, opals, pearls)
- Electronics (unless completely waterproof and safe)
- Watches (especially with non-metal bands or without water resistance)
- Wood (porous and absorbent materials)
- Delicate Plastics (soft polymers may melt or warp)
- Paper Products (anything absorbent or cellulose-based)
- Items with Loose Adhesives (can break down and separate)
Why Are These Items Unsafe for Ultrasonic Cleaning?
Each of these materials reacts poorly to the cavitation process that ultrasonic cleaners use. Here’s a breakdown of the risks:
| Item | Risk | Safer Alternative? |
|---|---|---|
| Gemstones | Can crack, fade, or lose finish | Gentle hand-clean with warm water |
| Electronics | Water intrusion and short circuits | Use isopropyl alcohol + soft brush |
| Watches | Water can seep in or damage band | Check watch brand specs before cleaning |
| Wood | Absorbs moisture, causing swelling | Microfiber cloth + wood-safe cleaner |
| Plastics | Can deform under heat/vibration | Use cold water if you must, test first |
| Paper | Disintegrates instantly | Never ultrasonic — dry brush only |
| Adhesives | Glue breaks down, items fall apart | Spot clean without soaking |
How Can You Use Your Ultrasonic Cleaner Safely?
When using an ultrasonic cleaner for dental or general beauty tools, it’s essential to follow a few core safety tips:
- Always read the product manual and check for approved materials.
- Use distilled water or recommended cleaning solutions — never harsh chemicals.
- Pre-rinse items to remove visible debris before placing them in the tank.
- Use a mesh basket to avoid direct contact with the cleaner’s bottom.
- Set appropriate cleaning time — never leave items unattended.
- Let items dry completely after cleaning to prevent corrosion or water spots.
