Granbo Ultrasonic Cleaner 800ML Jewelry Cleaner Ultrasonic Machine 40kHz with Digital Timer and Degassing,110V Digital Ultrasonic Parts Cleaner for Denture Dental Oral Irrigator Parts Glasses

Industrial engine cleaners are 25khz. Delicate cleaners are 100+ kHz. This is a fantastic medium range 40khz machine that can handle jewelry, eyeglasses, carburetors, spark plugs, scissors, etc. It’s simple to use. Just fill half way with water, add a splash of simple green max or dish soap, set temperature usually 35-40 C, push degas and allow air bubbles to clear for 1 minute, then add your item to clean and it’s usually done in a couple of minutes. For eyeglasses you only need 30 seconds. For delicate items like glued jewelry just push the semi wave button which decreases the power to half. It’s a little loud but you can handle it for 2 minutes. It’s especially satisfying to watch the grease come off your eyeglasses. Can fit 2-3 pairs of glasses in the machine at once.

A Game-Changer for Cleaning! I've been using the Granbo Ultrasonic Machine 10L 240W for about a month now, and I have to say, it's exceeded all my expectations! As someone who tinkers with watches, jewelry. I needed a reliable cleaner that could handle a variety of items without damaging them. This machine delivers on every front. First off, the 10L capacity is perfect for larger batches – I can fit multiple pieces at once, saving me tons of time compared to smaller units I've tried. The 240W power combined with the 40kHz frequency creates powerful cavitation that blasts away dirt, grime, and residue effortlessly. I cleaned some heavily tarnished silver jewelry, and it came out sparkling like new after just a 10-minute cycle with the heater set to 60°C. The degassing function is a nice touch too; it removes air bubbles quickly, ensuring even cleaning from the start. The build quality is top-notch – the SUS304 stainless steel tank and basket feel sturdy and durable, and I don't worry about wear even after daily use. The digital controls are intuitive: adjustable timer, heater, and power settings make it easy to customize for delicate items or tough jobs. Plus, it's surprisingly quiet for such a powerful machine, which is great for my home workshop. Overall, this ultrasonic cleaner has made my hobby so much more enjoyable and efficient. If you're in the market for a professional-grade unit at an affordable price, the Granbo 10L 240W is a must-buy. Highly recommended!

Great size for cleaning, automotive parts, tools, well, anything you could actually fit inside of a 3.2 L tank. It’s insanely easy to use, seems durable enough, has a heater inside, and quality seems great! My only complaint is the fact that this is metric, but not a dealbreaker. Results are absolutely amazing too! No leaks either!

This ultrasonic cleaner is the perfect size for my needs. It is simple to use and clean. I put mostly plain water in the bin and put my parts in a plastic bag with a small amount of Purple Power degreaser. It starts removing any and all grime immediately. The heat and timer functions work well. And it is very quiet when you fill the hopper/bin with a sufficient level of water. It would be nice if it had a drain function, but it is easy enough to just tip and empty it out, then wipe it down.
