What's the best cast iron carburetor cleaner now days?
Tried Berryman's, not so good.
Tried the molasses, takes too long.
Need the remove old coagulated gasoline, not rust,
so carb can be cleaned in blast cabinet without ruining glass bead media.

I cook them twice in lye water. 1st water cuts the crud & gets muddy. Rinse & blow it out good after using tip cleaners. Then cook it again. A little more mud will show up.
 
Cast iron I use the same caustic as boiling cast iron heads & blocks. Aluminum, Ultrasonic is best and I need a more powerful one.
 
I use either a Crockpot or and old blue enamel canner and a hot plate. Boil them in either Purple Power or Greased Lightning at full strength, anywhere from a few hours to overnight. Flush with water and compressed air. Poor man's hot tank.

Thanks for the replies, guys.
I gained access to a gallon of methanol alcohol today,
going to give that a try.
I've been warned not to let it get on my skin, or breathe any fumes.
If it catches fire, you can't see the flames, and hard to extinguish.
Same as fuel used at Indy, and top fuel dragsters.

Bake it.

I understand engine rem-man places have been doing that for a while now because the caustic hot tank method from the past generates too much hazardous waste.

I am experimenting with that method, have an oven in the shop.

NOT sure what a safe temp for a carb would be, but even 300? for a couple of hours wouldn't hurt the parts and would bake the organic sludge off of them.
 
If anyone watched that lawn mower repair guy that someone posted a link to a while back on you tube,He soaks small engine carbs over night in pure purple power.
 
Harbor freight ultrasonic cleaner with simple green. I used Gunk hydro solve, not my favorite. There just isnt any real good cleaners avail . Depending on carb type and how dirty it is I use several methods. I have a hot tank spray cabinet for cleaning engine heads and blocks. I used aluminum safe chemical in it. I have ultrasonic cleaner. 5 gal dip tank with agitator. Some times they get soaked in Lime away. Real bad they may go to bead blaster, pain in butt to get all glass residue out of ,but gets them clean and looking nice.
 
Boil them in soap water before you even start to take them apart and save a lot of head aches.

Guess i am one of the lucky ones as i have five gallon of the OLD and i do mean OLD Berryman's , you know the stuff that will remove four layers of hid if you get a drop on ya before you can wash it off . a friend found this stuff in a old closed up parts store he bought out and gave it to me . I have since had to put it in a new steel pale as the org. one started to leak . Take a holley carb and hang it from a wire and slowly dip it up and down four times and i don't care how nasty it is it comes out like a new casting . Stick in a nasty Farmall carb that has sixty years of crud and four hours and it is bare cast.

That stuff sounds just like the "GUNK" that I used to get at N.A.P.A. I lost the last one gallon container I had because it ate through the steel can. I didn't know it until it was all over the floor.
