Ultrasonic Cleaning Process?

[nastyjones]

I've said this before, use a solution designed for ultrasonic cleaners. Proper solutions contain a surfactant that actually gets under the crap on the carb and helps "lift" the grime off. Follow the directions on the label. I've probably cleaned over 250 carbs. 40 minutes and they're done.

I bought some eBay carbs that had been ultrasonically cleaned. The were pretty dark and had some white bits of crud on the inside.


Did a bit of forum research. Lime-A-Way was recommended. It got rid of the white crud & brightened the carbs up nicely.
Just limit the Lime-A-Way exposure time & use a brush.

That makes sense, can you share or copy & paste your formula for success? TIA

Maybe a bit more suitable, probably same as Ed is using.

I got the 3L version of this and it barely fits one carb.

I bought this one. Haven't cleaned anything delicate yet except for tank badges. I used almost a gallon of spray nine. 2x@ 50c and it took the paint right off. Oops,lesson learned. Figured if its that strong I'll use it on brake stuff. Takes a the clear coat off engine covers, then used scotch-brite for a great finish. Its really dirty now, but keeps right on cleaning. Its so dirty, I'm doing a sprocket, and sprocket cover next, then changing the fluid. I'm running out of really crusty stuff to clean

Mine is larger, 10L. and easily takes 2 carb bodies + parts. I won't tell you the name of the product I use (proprietary) but US solution+vinegar+dish soap+water. Results are amazing.

Are any of you cleaning the slides with the diaphragms in the ultrasonic cleaning.

[nastyjones]

Absolutely. Diaphragms get dirty too. Don't forget other parts as well. I clean brake calipers and master cylinders; virtually any part that can be submerged.
US cleans them all.

Agreed. All metal parts get dipped while everything gets a sonic cleaning. Floats, slides, choke plungers... Everything, including the parts that were dipped. After cleaning, everything gets a how water bath. I then poke and spray all passages with carb cleaner and then blow out with compressed air.
