Does anyone use an ultrasonic cleaner for bearings? If so what do you put in the container to clean them?
Thanks

I have a long time ago. I used the jewelry cleaner that came with it.

If it is a steen container you can use almost anything, but if it is a plastic container, be sure not to use something that will harm the plastic.

Mineral Spirits works great, less odor and flammability issues also much more economical than using other solvents/motor sprays.

I use an ultrasonic cleaner all the time on bearings. Higher wattage models will really help. I use this powerful one for about 3-9 minutes on bearings.

I put the bearings and mineral spirits or motor spay into a 1/2 oz glass bottle (like this). The ultrasonic waves transfer perfectly through the glass bottle to the cleaning agent to the bearings. I've used weak ultrasonic cleaners before that you could barely tell they are on. This ultrasonic cleaner is so strong it vibrates/tickles to hold onto the glass jar. When they are done and you take the bearings out, you can actually hear how clean they are by the sound they make when you handle them or spin them.
