Ultrsonic Cleaner for Hand Guns

clownboy
Brother and I made a investment in a used Ultrasonic cleaner.
Using the L&R solution, I gave it a try the other day. I put 2 field stripped semi auto's in at the same time. After 20 minutes the solution was very dirty. I gave them a good rinse off at the sink and although cleaner, I still had to wipe oil and dirt from the slides. Once completed they were noticeably cleaner and functioned better.

My understanding was that I could drop firearms in and the Ultrasonic would do all the cleaning. So now I am wondering if I A) Put too many guns in at one time, B) Just expecting too much from the equipment or C) The ultrasonic isn't working properly.

Do appreciate anyone's knowledge on this topic.

    I have two L&R ultrasonic cleaners and they clean all the oil and dirt. I only do one gun at a time.

    Ultrasonic cleaners work best with a warm solution. The ultrasonic energy will heat the solution but a cleaner with an external heater is better and quicker to temperature.

    The only drawback to ultra sonic cleaning a field stripped weapon is that some particulates may be mechanically captured, so I always completely disassemble the weapon first. As Mr. Stimson stated, all of the cleaners I know of work much better when heated and time is substantially reduced. Depending on which model L&R you have, it most likely has a heater built in.
