Ultrasonic cleaning is a process that uses ultrasound (usually from 20–400 kHz) and an appropriate cleaning solvent (sometimes ordinary tap water) to clean items. The ultrasound can be used with just water, but use of a solvent appropriate for the item to be cleaned and the type of soiling present enhances the effect. Cleaning normally lasts between three and six minutes, but can also exceed 20 minutes, depending on the object to be cleaned.
Ultrasonic cleaners are used to clean many different types of objects, including jewelry, lenses and other optical parts, watches, dental and surgical instruments, tools, coins, fountain pens, golf clubs, fishing reels, window blinds, firearms, car fuel injectors, musical instruments, gramophone records, industrial parts and electronic equipment. They are used in many jewelry workshops, watchmakers‘ establishments, and electronic repair workshops. – Wiki
We use our ultrasonic cleaner filled with water. In the water we place three jars. Jar one is Simple Green for all plastic and painted parts. Jar two is lacquer thinner for metal parts including bearings. Jar three is vinegar/water for corroded parts. After a quick cleaning 5-10 minutes all come out and are thoroughly rinsed in fresh water. After drying the parts are in great shape and every nook and cranny is clean. Salts, sands, all old grease and oil removed. Now the parts are ready to be re-lubed and assembled. No heat is ever used in the water as this could create an unsafe situation with the thinner.
The primary reason we invested in this tool was to reduce the overall time to clean reels. The added bonus is the quality of the work that it does in such a short period of time using the right agents. Very little post bath cleaning is needed even in the tightest of spots. One additional benefit that I came about on accident, I had a heavily corroded frame screw that would not come out even after all the tried and true methods. 5 minutes in the ultrasonic cleaner loosened the screw and it came right out. Hmmm where did I put those Newell frames and cross bars with the frozen screws….
