In the past I used the Gunk brand dip bucket, spray carb cleaner, Acetone, and finally heated ultrasonic cleaner.
Know of these worked great but did work OK
I was about to go buy some Berryman's but noticed that many (on the net) say the new stuff is not as good as the old stuff
Found a Youtube video that suggested MEK solvent
I have heard about using vinegar although have some slight memory of leaving alum. in too long that actually made the part darker
Then there is Pine Sole
I have a glass bead blaster but many say it's not worth the risk but did just order some nylon bristle wheels for my die grinder

So I turn to you guys that have had experience with some / most of these above mentioned products

I would like MEK to be the magic bullet but don't remember that Acetone worked all that well
Suggestions?

I don't even keep MEK around the house, just too nasty. You might try S100 bike cleaner. I was amazed how the carbs looked new with it just sprayed on. Try it in the ultrasonic (if it doesn't foam too much) And you can clean the bike too!

Will do.
I still have some S100 and was surprised how good it is for general cleaning; never tried it specifically on carbs.

I like lacquer thinner. Lowe's has it by the gallon. Just don't breathe it or get it on your skin, at least in large quantities.

Ultra sonic cleaner is the way to go. They come out so shiny

Aerosol Brake cleaner...not the so called enviro safe stuff.....And I've bead blasted nasty carbs without any problem. Just rinse well with water and blast all the channels with the brake cleaner; tape off the ports if your worried about them.

But my question is, what do you use as a solvent in it? I have one myself and have been experimenting- there are many opinions about what's best to use with it.

OK so I got a little crazy on this and had some spare H1 float bowls to experiment with.
So far have tried:
Vinegar
Oven Cleaner
Muriatic acid
multiple carb cleaners
MEK
acetone
lacquor thinner
Simple Green
Standard McMaster Carr multipurpose ultrasonic cleaner soap

The last items to try will be:
Boric acid
Phosphoric acid
Castrol Super Clean
Pinesol

If you have a few hours to kill, Google cleaning aluminum with Pinesol; can't tell if it's great or horrible by the reviews
Also read some interesting reports using a standard polishing compound ground up and mixed with Naptha from tuckers

For keeping the oxidation away I have Never Dull and will pick up some carnuba wax
Will report back in a day or two

Keep in mind that some folks think shiny aluminum means clean carbs and some of the things you listed are directed toward that end. However, in my mind, a good carb cleaner will dissolve the varnish build up within the ports of the carb body. Two different things....
Some acids, etc. may do wonders on aluminum but may not be able to penetrate gasoline varnish to be able to get to the aluminum.
