CREWORKSCREWORKS 30L Digital Ultrasonic Cleaner, Ultrasonic Cleaning Machine with Degas & Gentle Modes, Professional Ultrasound Cleaner with 600W Heater for Auto Parts

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 offHaving 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 resultsUsing 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 CThe 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 everythingAs 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 startingI 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 ragI 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 moneyVery pleased with it so far

Great little machine, cleans brilliantly just the right size

Seems to work. Not as noisy as I expected. 2 litre capacity is just big enough for a pair of glasses.

This was the best value stainless steel ultrasonic cleaner I could find in this size, with a heating element and complete with a basket and small parts container. It's Chinese built, like all the others, but distributed by a British firm based in Manchester, which gave me more confidence than ordering direct from China. It's robustly built and looks very solid. I've used it now a dozen times or more, mainly for watch cases and jewellery, which the small size is perfect for. Using the appropriate ultrasonic cleaning fluid and temperature, the results are outstanding - as good as any hightstreet jeweler can perform and at a fraction of the cost. One watch in particular (pictured) was caked in years of dirt. After removing the watch movement, ten minutes in this had it absolutely gleaming. Having the heating element means I can leave the same solution in between cleans and simply warm it back up when needed. Cleaners without heating elements are cheaper but require you to add fresh, warm solution each time or to clean at room temperature, which limits their effectiveness. By using the heating element I've only had to change solution twice, which is a significant cost saving over time. Overall I'm extremely happy, as you can probably tell.

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

Product arrived today as expected. I plugged it in and the fuze blew immediately, it was an internal fuse so irreplaceable by a non tech type person. This has delayed the fixing of my car as it was to be used to clean my injectors so less than impressed, they aren't cheap. I have returned the item and purchased a replacement in the hope it is a one off.

Bought to clean the carburettors from my motorcycle which were all gummed up with stale fuel, cleaned the residue without any damage to the castings and the brass jets.The cleaner has performed very well and if anything has exceeded my expectations, well worth the cost and has paid for itself in savings by doing this job myself instead of paying a third party to do the cleaning for me.

Works ok but doesn’t give the dazzling results you see on tv. Used it mainly on car parts. Could be the fluids I’m using I suppose, and they are expensive - no matter which machine you use.
