Topic: Ultrasonic Cleaning Fluid - What are You Using?

[BenelliSEI]

On the size topic(?), I do have a tank that will easily take a full rack of carbs (the one I repaired for a friend and stayed in my shop). But, I prefer to dismantle 100%. Doing the bare bodies, one at a time in the small tank, seems most effective. That last set took a bit of time but with a basic bench top sync., before installation, this was the initial read.

Has anyone tried using the NAPA carb cleaner in an ultrasonic cleaner (comes in a gallon can, like paint)? My little ultrasonic cleaner doesn't seem to do anything but jewelry-sized parts.

As long as you don’t heat the solution, I see any reason not to try it. Warming might create some toxic fumes? I’m just not sure it’s needed. I’m only using a 20:1 ratio of distilled water: Simple Green and it’s enough to get my carbs back to their original look and spotless inside.

John,do you heat your 20:1 ratio of Simple Green ?

Yes. Just to 35C.

Had my first experience with Ultrasonic cleaner last week...used a friends, so not really sure what kinda soapy stuff he had in there.  Did not break the Pd41a's apart because that throttle and choke linkage is kind of a nightmare.  Gotta say I was a little disappointed.  More scrubbing than a 15 minute bath of Gunk carb dip bucket and still not as clean after an hour.  One nice thing was the scrubbing was more pleasant than with the highly toxic Gunk.

The simple green aircraft stuff works great, the only down side is you just cannot as far as I can see walk into a brick and mortar and buy it.

Simple Green - SMP13406 Extreme Aircraft and Precision Cleaner

$28.50 on Amazon but one needs to be sure to not run out :-). It was kinda ho hum on oily greasy stuff but that is not it's normal use anyway. The kinda cheap "mean green" stuff does OK on that kinda stuff. The mean green did turn some aluminum gray but that was headed for vapor blast anyway.
