DEEP CLEANING IN 30 SECONDS
The Granbo Ultrasonic Cleaner can gently and effectively remove grease residues, streaks, dust, and bacteria from glasses in just 30 seconds.
Simply fill the water tank with water and detergent, place the glasses inside, and restore clear vision within 30 seconds.
THOROUGH & EFFECTIVE
A push of a button, some tap water and a dash of detergent is all it takes to remove even the most stubborn dirt from your glasses.
The Granbo uses ultra-high frequency waves at a frequency of 40khz to generate thousands of tiny air bubbles that thoroughly clean every last nook and cranny of your glasses through vibration.
ANTIBACTERIAL
In their current study, scientists at University of Pennsylvania analyzed 30 pairs of glasses worn in a university environment in three places each: Lenses, earpieces and nose pads. A total of 5,232 different species and 665 genera of bacteria were discovered.
Ultrasound technology thoroughly and gently removes germs and bacteria from your glasses, as every nook and cranny is intensively cleaned and even micro-particles, such as bacteria and germs, are dissolved by the high frequency of the ultrasonic waves.
PREVENTS SCRATCHES
Unlike conventional cleaning methods, which can often leave fine scratches on the surface of your glasses, Granbo works gently and thoroughly.
Granbo does not damage the delicate parts of your glasses or jewelry due to its gentle and effective ultrasonic technology.
This prolongs the life of your glasses and avoids expensive repairs.
MULTIFUNCTIONAL
Not only glasses, but also watches, jewelry, make-up brushes, dentures and other small parts can be cleaned in our Granbo.
The application possibilities are limitless, but the result is always the same: a hygienic cleaning that removes even the smallest dirt particles.

My husband and I always wanted a jewelry cleaner. So when I looked at the reviews for this one I knew it would be perfect. We first used it with just water it cleaned but not as good as I wanted it to. Then we cleaned our jewelry a second time with the solution and the jewelry came out super shiny. All in all 10 out of 10.

I knew my 5 year old watch needed cleaning. It has a linked band and I could see some dirt in there and my wife wanted some jewelry cleaned so I purchased this unit.
I started with my watch, I ran it for 2 cycles and the solution was almost black. The watch came out looking much better. Next was the jewelry and it came out looking better, but it was not as dirty as my watch band.
It is very easy to use, so I will use it every once in a while to keep it looking good

So one of my bracelets was lost in the garage and when I found it, it was gross and actually full of rust looking stuff and grimy. It was disgusting. The rest of my pieces were just getting dark due to regular wear. Well I received this machine yesterday and today I had my gross bracelet in it alone first for about 5 cycles. Well after I saw how AMAZING it worked, I put my other pieces in!! I am definitely happy I bought this!!!

I really like this ultrasonic cleaner. Started with cleaning sunglasses and eyeglasses. Yes, it cleaned the gunk that you can’t reach. BUT I did try this on a pair of mirrored sunglasses (not expensive) that had some of the mirror chipped off (very small yet noticeable chips) and I noticed it started to make the problem worse so I stopped the cycle. If your eye/sunglasses have a mirror or film coating that is already scratched, the ultrasonic vibration may accelerate the problem so do not use the machine with them.
Next used it to clean some watch bands. I did not submerge the entire watch because I’m not 1000% confident the battery is water sealed. I dangled the watch over the machine only submerging the watch bands. Watch bands did clean up nicely, both metal band and a rubber sports watch band.
I also cleaned some real jewelry and it did great cleaning the crevices. I enjoy wearing some of these earrings and necklaces daily, but grime slowly builds up and it’s nice to know I can give them a deep clean every now and then to restore them to original beauty.
I was cleaning with just plain tap warm water but decided to give soap a try like some others mentioned in their reviews. I tried a couple of drops of Castille soap and warm water and put in a pair of eyeglasses. That did not work well so do not use Castille soap. The soap left a strange film on the lens so I re-ran a plain water cycle and separately used a lens cleaner and I’m back to clean and clear glasses. (Maybe the frames liked the soap.) Haven’t tried the Dawn, but honestly the plain warm water was fine.
I put out these warning since there’s not a lot of literature or instruction that came with this item. User Tip: go slow with using this device and don’t immediately put in your expensive item expecting it to come out perfectly.
Happy cleaning!

I wear my glasses in a warehouse but don’t like walking around with dirty glasses, I didn’t want to take the lenses out just to clean them I searched how to on tik tok and ended up here. I’m more than satisfied with my purchase I got the smaller unit and its perfect for a pair of glasses or jewelry.
Pilling –
This machine makes diamonds sparkle like they just came from the jeweler. Did a decent job on my gold chain, but still needed to be polished afterward.
It doesn’t really clean silver at all. Gets the stuff out of the chain, but does not bring back that new polished silver look. You still have to clean it with silver cleaner. OK for the money.

I recently purchased this small ultrasonic cleaner to help clean some of my more delicate items, such as jewelry and glasses. I have been extremely impressed with this device and would highly recommend it to anyone in need of a reliable and effective cleaning solution.
One of the best things about this ultrasonic cleaner is how easy it is to use. Simply fill the device with water and place your items inside, and the ultrasonic waves will do the rest. The device is compact and doesn’t take up much space, making it a convenient addition to any home.
The cleaning power of this ultrasonic cleaner is truly impressive. It effectively removes dirt and grime from even the hardest-to-reach places, such as the nooks and crannies of my old glasses. The ultrasonic waves are gentle enough to not damage delicate items, but powerful enough to remove dirt and debris.
While this small ultrasonic cleaner is incredibly effective, one improvement I would suggest is the addition of a customizable timer. Currently, the device only has a set amount of time for cleaning cycles, but being able to program the exact amount of time would allow for even more customization and convenience.
Overall, I am very impressed with this small ultrasonic cleaner. It is easy to use, compact, and incredibly effective at cleaning even the most delicate items. It has quickly become a staple in my cleaning routine, and I would highly recommend it to anyone looking for a reliable and effective cleaning solution.
