Going to ultra sound clean the carbs. What do we use? Carb cleaner? Simple green? Never done this before. Help.

I used Simple Green Pro Heavy Duty (it's the purple one), worked well but I guess the regular one will work too.

I use Dawn dish soap, works good for me and it won't attack the aluminum like some caustic cleaners can.

I've used regular Simple Green, but after repeated cleanings, it will discolor the aluminum. The purple version is supposed to be a little easier on the material.
I have some citrus based degreaser that I might try. A better option might be to use that in the parts cleaner, and run dish soap in the ultrasonic.

I usually use some stuff I get from my ship called Enviromate 2000. If you've got access to a Drew Chemical dealer/distributor. Only issues is it comes in 5 gallon cans and needs to be cut down to 1 Enviromate to 4 water. I've been able to filter it through either a used couple of facemasks or folded paper towel and re-use it several times (as the Drew propaganda allows this).

Harbor Freight has a powder you can mix with water that seems to work ok. Runs about 7 dollars.

The one and only time I used dish soap I ended up with a massive mess of bubbles so I don't recommend that as an option.

I only use dish soap. About the same sized squirt you'd use to do your dishes but in only 3 or 6 liters of water {machines capacities}

Might be a brand or amount thing but I don't get bubbles - or blackening.

Citrus cleaner too can cause blackening,

The issue might b that people overuse dish soap for their dishes.. you only need a few drops.. the extra suds dont clean....
Maybe we need mls per tub recommendations??
Technically 1 drop is 0.05ml....yeah 20drops=1ml.

I've tried numerous solutions, with my current favorite being Berryman's B12 carb cleaner with water. . Even though B12 is insoluble in water, the ultrasonic vibrations do seem to distribute it throughout the carb.

I haven't tried the purple Simple Green, but can testify that the regular SG will cause discoloration depending on strength and number of cycles.
Here's an example from a GL1100. The carb is discolored, the plenum is not.

I take a gallon milk jug and fill it with as hot tap water as i can get (gives the process a jump start instead of trying to get up to temp with the heater only), put a squirt or 2 of Dawn in the jug, fill the unit and off to the races. Does a great job, cleans out old gas varnish and everything. No danger of discoloring the aluminum either. I've used it on the master cylinder, brake calipers, etc. It's my go to for anything that will fit in the unit. I've never had a "bubble issue" before?

 

[CXPHREAK]

Yep, always start with hot water.

I actually always chemically dip for 24 hours first.

I also used the purple Simple Green HD and it worked great. It is advertised as safe for metals.

15 liter Vevor on Amazon is a pretty good bargain. That's what I got and I am pretty happy with it. I drooled over the 58 and 77 liter but was not about to spend $900-$1500

This Simple Green Aircraft works amazing in the ultrasonic.

Warning, it has mix limits and can be dangerous to your material if you mix wrong.

I forgot to take before pics, but the after pics had the carbs on my 1983 GL650 looking showroom fresh.
