Using any kind of abrasives is a bad idea, nor any chemicals that contain acid that will attack the alloy body of the carb. Most carbs have very small passages throughout the body and getting all the abrasives out is hit or miss. The best solution is to get an Ultrasonic cleaner. Harbour Freight has a good one for $75, less if you have a coupon. I use Mineral Spirits in the machine which heats up the liquid and is just big enough for a carb body and parts. You may have to rotate the part to fully submerge all sides. Leave it in over night, and no matter how varnished or sooted up the carb is, it comes out like new the next day. If the body is corroded, it will remove the loose corrosion, but that carb is toast anyway. Otherwise, it is the safest and most efficient system for carb cleaning. All of the professional carb guys use a machine like this, albeit larger and a lot more expensive. The high frequency vibration, coupled with the hot Spirits will dissolve all of the grime and hardened varnish in every interal part of the carb. I also use it for cleaning distributors, and other small parts. And if you are one of those guys who has to justify it to the spouse, it also does a great job on jewerly lol.

Good to see you back by the way. I thought that caustic attacked alluminium making it go black?

The product that I referenced will take off skin, it will take off paint, it will soften carbon deposits, I am not an expert but I have used it and it does a lot and can be used with good results if care is taken and you learn how to use it. The carbs on the sows ear engine were dipped for a couple of hours and rinsed well with HOT scalding water, there was still some crud still in the float bowls that was scraped out with some picks and a flat blade screwdriver, the exterior still has some scale and probably should have been dipped again but I was at Carl's and they were dipped over lunch and at about 3pm I pulled them and rinsed and then used compressed air to blow out the rest of the hot water . These Webers may not be perfect, they are a "good enough" for the desired job and will suit the rest of the Elan. With a bit more work they would look a lot better but I guess I am someone that looks at the benefits of perfect looking Webers on something that may look out of step with the rest of the car. Oh almost forgot the question, the dip is for carbs, maybe caustic is the wrong word but it does what I said in the fist line and it does not turn the carbs or aluminum black.

The ultrasonic cleaners are pretty good for outside surfaces. The sound agitates the chemical and cleans pretty well. We use them at work. They use a butyl ethanol detergent. I don't think the UT cleaners are very effective deep down in the passages like caustic parts dip was.
The old "parts dip" and "carb dip" is sodium hydroxide, "caustic soda" is another term. The chemical companies that sold it put a layer of oil on top so the stench would not be so overwhelming when you opened it. Its really dangerous stuff for the average person. It can cause serious chemical burns, particularly to mucous membrane. So you never want to get splashed in the mouth, nose or eyes with it. The chemical burns are hideous and take years to heal. Do an MSDS search on sodium hydroxide and you will understand. You should wear nitrile gloves, rubber apron, rubber boots, goggles/faceshield. I have seen good work boots ruined in minutes with that stuff. Its hazardous waste when you are done too. We can no longer buy it here in Kalifornia. The replacement products are pretty worthless.
I get the objections to abrasive blasting. Thats why I brought up trying it on an old zinc part, with varying air pressure. The glass bead/powder that the Porsche/Weber guy uses is extremely fine and he uses lower air pressure so it doesn't harm the metal.
Walnut shells are very soft. We used walnut shells once a week to clean the compressor section of a gas turbine running at full power. At the 3 year inspection there was no damage to the blades. When you are done, wash everything thoroughly.
All said and done, use caution and do the research. Your results may vary.

By "leaving it in overnight" I assume you mean just soaking, not with the ultrasonic running ?
Probably pay to be a bit cautious with a flammable liquid in an ultrasonic because they do heat up any liquid in them.
So, don't leave unattended, and keep a good fire extinguisher handy.....

Ultra sonics.... My (big one) is electrically heated and will take the (water based) agent up to about 70 degrees. I give stuff no more than 30 Min's and they come out like new. Used by myself for many purposes including Tooling (cutter blocks etc) for industrial woodworking machinery. No skin off and no fumes! .... But.. nice clean parts etc.. Tests on carbs (small ones albeit) have been very positive so far. No chance of damage I like mucho...

My question is whether cleaning the Weber bodies with a blast media of crushed walnut shells would yield good results? Has anyone here ever tried this?
Thanks,
AMA
not tried any nuts! but have tried GUNK degreases but leaves an oily finish on outside stops it going moldy (outside)only,also have stipped and soaked IDA`s in desolve to get insides cleaned up worked well. hope this helps

I would try dry ice-blastig to clean the carbs (or anything else in side the engine compartment):

Dunk? is this a product? I cannot find through Google, I though most of the carb cleaners that work were banned due them being toxic. I have on far to many occaisions to remember cleaned my carbs inside and out using fine glass beads, it is a tricky process to get all of the beads out and you really do need to be able run a tap down all of the threads to get them properly cleaned out. When you think about it carbs are alluminium and as long as you do not use a coarse abrasive like garnet there really is no reason not to use an abrasive.

After lunch with a bunch of old car guys, we visited one of their garages. The subject of cleaning cabs came up, and young whippersnapper of the group, opined that soaking a carb in Pine sol for a couple of days would leave it looking like new. He did advise that the steel parts would turn a little brown. I have a pair of old Webers and I think I will take the float bowl covers, strip them and give it a try. Anybody heard of this?

I intend to use an ultrasonic cleaner to give a pair of webers the once over.
How far should I go in removing the brassware from the internals of the carbs?
If I remove the parts within the circled area in the attached photo will I ever be able to fit them back in again?
The 2 remaining brass screw heads are easy to remove - but the brassware hidden beneath the screws might give me a problem - along with all the other bits which are still visible.

The ultrasonic won't harm brass on its own, it will depend on what cleaner you have in it.
Unless the cleaner has some bad effect on brass, ( easy enough to test ), why would you go to the trouble of removing all the brass?
Why not hang just a small part of the carb in the ultrasonic and see if the ultrasonic has any effect ?
