If you’ve ever wished for a faster, safer way to make your everyday essentials look brand new, the Donirt Ultrasonic Cleaner is your new go-to. From jewelry and glasses to baby bottles and circuit boards, this compact powerhouse uses ultrasonic waves to lift away grime from places brushes and cloths simply can’t reach. It’s fast, easy, and surprisingly satisfying.

How Ultrasonic Cleaning Works
Ultrasonic cleaners create microscopic bubbles in water through high-frequency sound waves. These bubbles collapse on contact with surfaces (a process called cavitation), gently dislodging dirt, dust, oil, and residue from every angle—even inside tiny crevices and intricate details. The result is a thorough clean without harsh scrubbing.

Why Donirt Stands Out
- Quick, simple operation: Add water, press start, and let the cavitation do the work.
- Deep reach for complex shapes: Ideal for items with holes, grooves, hinges, and fine details.
- Tiny-place performance: Removes stubborn dirt, dust, and grease from areas you can’t reach by hand.
- Versatile cleaning: Jewelry, glasses, circuit boards, accessories, headgear, brooches, pens, toothbrushes, dentures, baby bottles, fruits, clocks, and more.
- Optional UV function: The rechargeable model includes a built-in ultraviolet feature that helps sterilize items for added peace of mind.

What You Can Clean
Great for:
- Jewelry made of gold, platinum, titanium, stainless steel; diamonds and most hard gemstones
- Eyeglasses and sunglasses (non-coated or hard-coated lenses)
- Metal watch bands and waterproof watches (band only for non-waterproof)
- Shaver heads, razor cartridges, dental tools, dentures, retainers
- Pens, mechanical pencil parts, small tools, coins
- Baby bottle components, silicone nipples, pacifiers
- Fruits and small produce to loosen dirt and residues (rinse thoroughly afterward)
- Circuit boards and electronic components that are fully disconnected and safe to submerge, followed by proper drying

Use caution or avoid:
- Soft or porous gemstones (pearls, opals, emeralds), glued-in stones
- Antique or plated items with fragile finishes
- Contact lenses, hearing aids not rated for ultrasonic cleaning
- Non-waterproof watches (do band only)
- Electronics that aren’t designed to be submerged or dried thoroughly
- Items with cracks or loose parts that cavitation could worsen

How To Use It (Step-by-Step)
1) Fill the tank with clean water. For oily grime, add a drop of mild dish soap or a specialized ultrasonic solution.
2) Place items in the basket without overcrowding. Keep pieces from touching if possible.
3) Set the cycle and start. Typical cycles run 3–5 minutes; repeat for heavily soiled items.
4) Rinse items with clean water and dry with a soft cloth or compressed air (especially for crevices).
5) For the rechargeable model’s UV function, run the UV cycle as directed to help sterilize surfaces.

Pro Tips for Best Results
- Warm (not hot) water boosts cleaning efficiency.
- Pre-rinse very dirty items to keep the tank water cleaner longer.
- For jewelry, remove loose stones and avoid porous or soft gems.
- For circuit boards, use distilled water or appropriate solvent and ensure complete drying (24–48 hours in a warm, ventilated area; isopropyl alcohol rinse can speed drying).
- Change the water when it becomes cloudy; clean the tank after each session.

Frequently Asked Questions
Does ultrasonic cleaning scratch items?
- No. The process is non-abrasive. However, fragile coatings or already-damaged finishes can flake. When in doubt, test a small area.

What solution should I use?
- Most jobs need only water. Add a drop of mild dish soap for oils. For specialty tasks (like jewelry), use a cleaner formulated for that material and follow the label.

How long should I run a cycle?
- Start with 3–5 minutes. Repeat if necessary. Extremely dirty or complex items may need multiple cycles.

Is the UV feature a replacement for disinfection?
- The UV function on the rechargeable model helps sterilize surfaces, but effectiveness varies with exposure time, distance, and line-of-sight. Use it as an extra step along with normal cleaning.

Can I use it for fruits and baby items?
- Yes for general cleaning. Rinse thoroughly afterward. For baby items, follow manufacturer care guidelines and your normal hygiene routine.

Is it loud?
- It emits a gentle buzzing or humming typical of ultrasonic units; most users find it acceptable for countertop use.

Care and Maintenance
- Empty and wipe the tank after use. Never run the machine dry.
- Use only the recommended liquid level.
- Store in a cool, dry place with the lid open to prevent moisture buildup.
