Ultrasonic carb cleaner…

[fleetwin]

Finally got one of those ultrasonic carb cleaners. Tried it out on an old crusty/rusty carb using hot water and pine sol. Seemed to do a nice job on the crusty jets, and nozzle, got most of the crust off the bowl and carb body also. But, the orange rusty looking coating remained. Just looking for tips and recommendations on non flammable solvent/cleaners to use in this cleaner that might help remove the rust staining from the carb castings…
Any other tips would be appreciated as well….
Thanks

I’ve been kicking around getting one of these. There’s quite a few out there…is there any of them to stay away from? What size works for most of what we do with our type motors? The 6Liter units seem to be a nice size by looking at the pics.

Hi Dan,
The 6 or 10 liter are nice sized ultrasonic cleaners depending upon your budget. The one I use is a 3 liter which works good for small motor carburetors and parts, but if I was to purchase another unit I would go 10 liters or larger to have the option to do automotive carburetors and larger parts too. As for brand not sure which are better, seems there all Chinese made so you are just taking a chance there. I have to say they do a real nice job and make the carburetor parts look almost new. Hope this helps you.

Tried the CLR, but was disappointed. Admittedly, I used a small amount mixed with hot water, but this is because the bottle said CLR should not be used with aluminum.. But, aren’t many coffee pots, etc lined with aluminum? Maybe I have diluted the CLR too much to be effective….

there are several rust removing gels .. one is made by the folks selling KRUUD have you tried a simple small wire brush ?

I do not think “stains” would be a big issue clog wise in your carb anyway

some of these rust removers use phosphoric acids .. I would apply only on the stains since the rest of the carb seems to have cleaned up enough

Don,
I agree with Rusted Junk, I have been using Extreme Simple Green Aircraft Cleaner for about 3 years and it has been great. Its highly recommended for aluminum. $14.35 a gallon at the link below

My mix is a bit different being 50/50 with water.
If your unit has a heater, throw that on for about 20 minutes before you put the parts in.
My wife also likes it for her jewelry….ha ha .

True, the remaining rust stains will not cause any issues I’m sure…Just experimenting with an otherwise junk carb… This carb body has all sorts of walls/baffles up inside the carb body, can’t really get at them manually with a small tooth/wire brush…
