Harbor Freight ultrasonic cleaner, Before & After pictures...WOW!!!
So I bought this thing last night for 21$, I had good things about these but really did not think it would live up the the hype. I am restoring a 1974 United Unique shuffle alley and I need to clean the 30yr old grease from all the steppers and score reels. For the last 2 days I have been dissassembling every reel and taking a toothbrush and simple green to every little piece, then carefully re-assembling it. Clearly this would take about 2 to three days of 8 hrs a day. If there was any easy around this method I wanted in. Anyway, I think the pictures speak for themselves. I do not even have to disassemble the score reels ! I can just remove the coil and switches and drop it in. I can only fit half of it in at a time, so I run each side for 2 3minute cycles,12 minutes total for each score reel, and here is the results.
I can also put a frozen stepper that is caked with grease and will not reset, and when its done not only does it look brand new but the wipers slide effortlessly over the bakelite. AMAZING
