CREWORKS Ultrasonic Cleaner with Digital Timer & Heater 15L | Stainless Steel Ultrasonic Cleaning Machine, Professional Ultrasonic Parts Cleaner for Jewelry Watch Glasses Denturess

As a keen year round cyclist one of the downsides is filthy bikes and drivetrains. I have tried various strategies of cleaning frequency and methods but the bottom line is that if you don't clean chains and cassettes thoroughly during the winter the wear rate is unacceptable. Initially I used a paintbrush, white spirit and an old baking tray but this was labour intensive, stunk of fumes and left me with dirty solvents to dispose off. About 2 years ago I bough a parts washer and used a water based de-greaser which was much better as I could leave the parts under the flow whilst doing other things but I still had to brush / agitate the parts at the end to get the really sticky grease off Having seen on YouTube people using ultra sonic cleaners to great effect I decided to get one. I got the 15L one so it would take a cycle chainset in without issue. So far I have used it for chains and cassettes with good results once I sorted out the better settings. What I found has worked well was a water / water-based degreaser mix (about 75/25 ratio) at 40-45 Deg C and for about 20-30 minutes. This has given good results Using just water for me (cold or at 40 Deg C) really did nothing and this mix with degreaser made a big difference. Also even with degreaser I got a lot better results when it was at around 45 Deg C The good thing is that you can just put in in and leave it running. I have still needed to give a bit of a wipe / brush on small areas at the end where the dirt is very ingrained - I could put it through another cycle and it would probably remove everything As others have said its quite noisy, but this is inherent - it has a speaker excites a container that acts as a loud speaker. Heating the fluid takes some time but it is only a 300W or so heater. I have also not filled mine much more then deep enough to cover the components I have cleaned so far which is about 5L. So heating a full 15L tank would take a long time. As others have said in this case filling it with water from a warm kettle would help, or just turning it on for 30-40 minutes before starting I fitted a hose tail to the tap so I can drain the fluid back into a container and reuse the fluid. Its good to see a lot of gritty sediment in the bottom of the container after use as it shows its working. I wipe this out with a rag I am not sure about longevity - there are a few reviews of people using it a few times and it being broken - let's hope they are anomalies. Bought mine when it had a discount code applied that made it a bit better value for money Very pleased with it so far

I have used a few of these cleaners, and I found this one to be the most practical size. Its large enough to clean most of the tools and circuit boards that I use it for, but no so big that the tank takes for ever to heat up. I have had really good results cleaning garage tools (using the correct solvent of course). The tools come up like new, and all the greasy marks just disappear. Very easy to use and clean.

Needed to clean an old carburettor so it could be dismantled and rebuilt. The ultrasonic cleaner did an extremely good job and removed oil/dirt/grime. I used cleaning fluid, 40'C temp and 3 six minute cycles. My only complaint is the in built heater is weak and very slow to heat the fluid. You're far better using a kettle to heat the water and add the fluid than using the heater.

Excellent size, works well, although takes a while to warm up, very easy to use.

Excellent bit of kit, loads of room, comes with a drain attachment to let you store the cleaning solution in a seperate container, temp control a but erratic but quiet in operation

Always wanted one or thought I needed one (but didn’t want to afford one). Now I have it has come in handy indeed. Initially it can look to be quite expensive to run but after a YouTube video found that you can be a lot more flexible with it. I now clean my motorcycle parts using petrol but in either a sealed glass pickle jar and just float it in the tank filled with distilled water. Doing this means I can reuse the water many times over as the water never gets dirty and even the petrol can be strained and reused more than once. (No need to use the heat function when using petrol I’d say!!!) At the price it’s a great deal and I know it will be used and useful.

It really does clean them up but using the special fluid sold separately is a good shout too.

Great item. I’ve only used it a few times so far to clean some PcB’s the size is pretty big it’s wide and long as opposed to deep like some. The cage does limit the size a little bit but not much

El producto viene muy bien empacado y es de muy buena calidad. Tiene la función de calor y de limpieza. Normalmente solo utilizo la de limpieza. Contiene una llave de drenado para facilitar la limpieza

Many people have said it is loud. Well, duh, it is a SONICation bath! It is no louder than any I've used. Mine is in a separate room in my shop. I wear ear protection when I'm near it. That is more for comfort than necessity. It is not that it is loud, but it is an irritating sound. That is all normal though. It does a great job cleaning tools and clock mechanisms. I was surprised that not only is dirt removed, but the brass seems polished! I love it. The drain fitting was easy to get a threaded barb from the Home Depot. Good tool.

Es muy eficiente y práctico

Have used it many years. Works well

Ordered this cleaner after researching and then watching an excellent demo on YT Steve's Small Engine Saloon. Price with discount was very fair. Seller had excellent reviews especially for customer service. Amazon was supposed to ship it in an added plain Amazon box which I had checked off in my order but they did not. Bottom of box had damage on one bottom side from an apparent drop but is very well protected inside and around cleaner and no damage was done. I did my initial set up reading the very vague instructions first. I filled unit with warm water and the unit doesn't seem to heat unless the timer is set and unit turned on to start cleaning action. I will do a follow up on that. Initial heating is very slow. Cleaner only displays temp in centigrade but easy to get used to. I used a cooking thermometer which reads in both units to compare reading and get myself acclimated to what I wanted to set temp to which is very accurate on the digital read out. First use was to fill unit completely above included basket with warm water and a small amount of Dawn dish wash soap. There is no fill line on inside of unit and instructions do not say that it is important to fill completely like many people say is important. I watched the little demo video on the product ad and it shows them only filling the unit about 2 inches just above the eye glasses they were cleaning! Everything else I read about ultrasonic cleaners warns against under filling! I decided to clean a couple combs, brushes, coins and misc. and was not impressed initially but knew I needed to educate myself on how to use it properly. My main usage will be using it in my home shop restoring and cleaning everything mechanical, carbs, machined lathe and milling machine parts and many restoration projects. Ultrasonic cleaners have been around since the late 1930's early 1940's so I know they are a good investment as long as it is a descent unit as I believe this one will be for my use. In conclusion, I now know my initial mistakes, mainly because of the poor info that comes with most of these units. First- it is very important to degas your water and cleaning solution. Second-experiment to find the correct cleaning solution you will need for what you are cleaning. Third-which will take a lot of trial and error, know what time and temperature works best with the item and solution, be it water, solvents, or flammables being used and the correct way to put them in the tank without contaminating your water and not expelling fumes. Best advise is to NOT USE FLAMABLES unless your unit is designed for it, which this unit is NOT! I will definitely be doing future reviews and updates on my cleaning projects using this ultrasonic cleaner and giving my no BS opinion and progress. Hope this was helpful. Thank you, DoneWrenching.
