This cleaned my jewellery far better than expected.

Removed dirt and grease surprisingly well.

I have had a couple of ultrasonic jewelry cleaners over the years, but NOTHING COMPARES TO THIS PROFESSIONAL CLEANING MACHING!!! The GARVEE 6L Ultrasonic Cleaner, 40kHz Professional Ultrasonic Cleaning Machine with Digital Timer and Heater with Stainless Steel Basket is a most impressive machine. It's durability, versatility and cleaning performance are second to none. You could fit everything but the kitchen sink in there as well, haha.This is seriously the most versatile cleaning machine that I have ever seen!!! This ultrasonic cleaning machine works wonders for reaching deep into eyeglasses, watch parts, and headphone filters to remove dust and grease. It works great for dentures and contact lens cases. It cleans silver jewelry and small mechanical parts by removing oxidation and oil without surface damage. It effectively cleans metals, plastics, and delicate items without causing abrasion.This machine is continuously blowing my mind with how well it works. What impressed me the most was the job that it did on a set of antique silverware that I had put away. It had been my grandmother's. It was very badly tarnished and oxidized with age, and polishing it by hand would have been a painstakingly-tedious chore. It was a chore that I had been putting off for many years. I packed up the silverware and into the machine it went. I let this machine run for a full 30-minute cycle, and voilá, the silverware was sparking clean and restored to its former grandeur. I did not think it would have been possible to do this good of a job by hand. Similarly, this machine does a SPECTACULAR JOB on our eyeglasses. It really gets all up in there, reaching deep into the eyeglasses to remove every bit of dust and grease. We really enjoy wearing our sparkling-clean eyeglasses:-)The GARVEE 6L Ultrasonic Cleaner meets U.S. standards for electromagnetic interference and is certified by the FCC (Federal Communications Commission). It also meets European safety, health, and environmental requirements and is CE certified. It is RoHS compliant with restrictions on hazardous substances (limits use of lead, mercury, cadmium, and other harmful materials), and UL-certified by Underwriters Laboratories, one of the most recognized U.S. safety certification organizations for electrical products. These certifications indicate it has been tested for electrical safety, electromagnetic compatibility, and restricted hazardous materials, thus giving a solid level of confidence for home and professional use.This machine is worth its weight in gold (or silver, haha). It has already paid for itself by saving me the time that I would have spent doing tedious cleaning jobs. This is an excellent ultrasonic cleaner that is easy to use and cleans amazingly well. Instructions are included for easy reference. This ultrasonic cleaner gets into all the nooks and crannies. Dirt can't hide from this machine. I highly recommend it!!!

This GARVEE 6 liter ultrasonic cleaner is just about the perfect sized cleaner for anyone wanting to clean anything from fine jewelry to small auto parts. This ultrasonic cleaner uses special sound frequencies to shake the water on a microscopic levels which causes grease and debris to literally melt off just about any item you put in there. It also has a heating function to heat the water up to 176 degrees for even tougher debris and grease.To test, I used this cleaner to clean three of my wife's rings plus two pairs of diamond earrings. Before receiving this cleaner, I found some really good cleaning tips online. Instead of filling the entire unit with a special cleaner, many suggested filling it up with just water. Then put your items you want to clean in a ziplock bag with the cleaner, squeeze all the air out and set that in the water. This is a great way to help save money on a large amount of cleaning solution. You can also set a mason jar in the water on the included rack and fill that with enough cleaner to cover your items. The bag seemed to work really good for me and less mess!The starting temp was 73 degrees and to reach my set point of 150 degree took about 50 minutes. So it does take a while to heat up. Once the water was ready, I put her rings into a bag of really hot tap water. She didn't have actual ring cleaner available, but I read online that just using water and a couple drop of Dawn dish soap works just as good. I ran the cleaning cycle for ten minutes and then ran it again for another 7 minutes. Once done, I opened the bag an poured the liquid and jewelry in a white bowl so I could see the debris it removed. To my surprise, there was quite a few small specs of debris it shook loose from under the diamonds!After I pulled the jewelry out, I decided to try something else I saw online. I used my espresso machines milk steamer/frother to blow hot steam around the smaller diamonds. Between the ultrasonic cleaner and the streamer, the rings and earrings came out almost like new. I inspected the back side of the diamonds with a magnifying glass and there was no remaining dirt particles what so ever!Overall, I'm extremely impressed with this cleaner. It's definitely not small, but it isn't oversize either. I'm really happy I ordered the 6 liter unit. It should handle just about everything I'll ever need to clean. Based on the build quality, the heating option, various sonic cleaning options, and the price point, I consider this cleaner an extremely good deal and would definitely recommend to anyone that has small parts or jewelry cleaning projects!

I noticed the best results when using the heater and giving parts a full cycle. It removed oily residue from small metal pieces pretty well without much scrubbing after.

Simple controls and decent cleaning power.

I used it on small mechanical parts with a proper cleaning solution, and it saved a lot of brushing time. The 0 to 30 minute timer is convenient.

Bought it for a small repair bench. It is not silent, but the noise level is reasonable for an ultrasonic cleaner. The lid helps, and the handle makes it easier to move.

Cleaned rings and glasses nicely.

I picked this up for dentures and small personal items. The gentle mode is useful when I do not want to run a more aggressive cycle. It feels like a good home and workshop crossover tool.
