Granbo 1L Jewelry Cleaning Ultrasonic Machine 40kHz with Digital Timer and Degassing,110V Digital Ultrasonic Parts Cleaner for Denture Dental Oral Irrigator Parts Glasses and More

This ultrasonic cleaner came with; the ultrasonic cleaner with lid, a metal basket, power cord, a cloth for cleaning, and an instruction manual. The instruction manual isn't very descriptive but this ultrasonic cleaner has only two buttons, an on/off and a timer, so it was pretty easy to figure out how to get it to work. The cleaner doesn't self heat so I recommend heating the water before use, it will work much better that way. The description mostly described using for jewelry, glasses, etc but used it for cleaning a small motorcycle carburetor. It was a little small for this purpose but it did clean it quite well with just water and some degreaser. All in all, I am pleased with the capabilities of this Ultrasonic Cleaner and I think it is a good choice for the light duty cleaning of any small items that one needs to clean.

First off, know that the directions are really lacking in this unit. It took research on my part to figure out what degassing was and why it was necessary. The instructions barely mention how to put the unit in degassing mode and definitely don't say when to use it. Secondly, don't use water with this expecting noticeable results. For testing purposes, I used some dirty pennies that I tried to clean. After using tap water at different time intervals, there was no noticeable difference in the pennies. It wasn't until I used Simple Green cleaner in the machine that I noticed the pennies were cleaner.Also, know that this machine is quite noisy. I don't recommend this for use in the home. Keep it in the garage or shop.

The instructions for this are not very user friendly. Not only does it not tell you what every part is for ( there's a white plastic slotted bridge) I have no clue what it's for. When trying to figure out how to work properly it gives more attention to troubleshooting than to proper utilization. The first thing I noticed upon operation is the timer is off. 5 minutes was more along the lines of 3-4 and the 3 minutes was more like 2. I do not know how much that matters to cleaning but will update once I try a few things.Just cleaned fiancé's engagement ring, ran a 5 minutes-ish cycle and 3 minutes-ish cycle. There seems to be a bunch of gunk from it in the bottom of the pan so that's a plus.I originally bought it to clean coins safely and depending on how well and if I causes any damage I'll add or subtract stars. Not going to put any that are valuable until I become more knowledgeable with this cleaner.

I’m thrilled with this ultrasonic jewelry cleaner! It offers a powerful cleaning effect, which efficiently removes dirt and grime from my delicate items. The capacity is perfect for cleaning jewelry, eyeglasses, and other small items. The degas mode is a nice touch, improving cleaning efficiency and extending the equipment’s lifespan.Although I was tempted to deduct a start due to the terrible instructions, which did not make operating this a user-friendly experience, the product performs well and so far has done everything advertised, so it didn't seem right to rate the product itself based on bad instructions.Overall, it’s a solid and durable cleaner that delivers great results.

This Ultrasonic Cleaner has exceeded my expectations in every way. The 40kHz frequency combined with the digital timer and degassing function makes it incredibly effective at cleaning a wide variety of items. Whether it's jewelry, dentures, glasses, or small dental parts, the results are consistently impressive.The digital controls are easy to use, allowing precise settings for different cleaning needs. The 1-liter capacity is perfect for household use, and the machine operates quietly, which is a nice bonus. The sturdy construction and compatibility with standard 110V outlets are also great features.Overall, this Ultrasonic Cleaner is a fantastic investment for anyone looking to keep their belongings in top condition. Highly recommended!

We have cleaned rings, bracelets, and necklaces with this unit. It is straight-forward to use and has provided great results.Note that we found Blitz Gem and Jewelry Cleaner to be effective as a cleaning agent.
