I used this ONCE in a sonic cleaner and the fumes nearly got the better of me. The sonic cleaner rapidly evaporates the the ingredients other than the transmission fluid. I DO NOT RECOMMEND USING IT IN A SONIC CLEANER.
With that said I've tried a number of home solutions but finally broke down and bought L & R Gun Cleaning Solution and it does an outstanding job. It's expensive, but like Tootsie Roll it "lasts a long time." I did manage to pick up a trick from the Ed's Red as I used automatic transmission fluid as my lubricant. I have two sonic cleaners, one with cleaner and the other with lubricant.
