14L Commercial Stainless Ultrasonic Cleaning Machine JPS-50A with Digital Timer

This unit works very good for doing carburetors and bolt carrier groups for my guns. I got the 14 liter and it has plenty of room for what I use it for. I am very pleased with the cleaning action of this ultrasonic cleaner. It heats up rather slow but if you turn the ultrasonic cleaner on while your heating it it will help it heat up a lot quicker.
I would definitely buy this product again.

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.

We are using this for cleaning Musical Instrument parts such as Silver Plated Brass Mouthpieces, Plastic & Hard Rubber Woodwind Mouthpieces, Silver Plated and/or Lacquer coated Brass Musical Instrument parts. The unit arrived quickly and was packed adequately. Set-up was quick and easy. We added a brass fitting to the drain to attach a clear vinyl drain hose since this unit is being used on a counter top. This is our findings after using it for a month about a few hours each day.

The settings for the temperature are in Celsius so many will have to convert temperature accordingly. It does take a lot of time (30 minutes), to heat up the solution (40 C), so plan accordingly if your cleaning requires heat. Conversely, if you are doing several batches of cleaning, be careful about the unit going over the set temperature, (according to the read out on the panel). We've turned it off in between uses to avoid burning out the heating element.

The cleaning power of this unit seems to be adequate for general use. Longer or repeated cleaning periods may be necessary for some items. It is dependent upon the severity of the items to be cleaned and what solution you use. We are going after calcified deposits inside brass tubes and have experimented with a few different solutions. So far, our best results have been with a mix of White Vinegar, Baking Soda and Sea Salt. Another good cleaning solution is a dilution of Simple Green HD and Dawn Ultra Dish Detergent. Both of these have worked well being heated between 35-45 degrees Celsius at 10-15 cleaning times.
