Would putting the solvent and parts in a crock pot and warming them up a bit be a good idea or am I just asking for trouble?

If that is the case maybe use a citrus based degreaser like "Simple Green"?

What about using anti-freeze?

Seems to me that I recall most auto engine shops use a process called "hot tanking" to clean parts before rework.

Re: Cleaning canister mufflers

Brendan grace and I just cleaned ours. Use a tall pail full of hot water. Get powdered Oxyclean. Pour a scoop full first in one end and add a couple of cups of boiling water. The oxyclean will quickly activate and start to foam. Upend the canister into the hot water. The oxyclean will eventually come out the other end along with a ton of carbon and black gunk and will continue to froth for a while.
Wear gloves and safety goggles and do it outside! The fumes are deadly.
After a while shake and flip the cans. Throw out the water, rinse and repeat alternating ends until the pipes are clean.
We used an entire box ( well Brendan did) and it took about five or six procedures. One of my pipes is still a little restricted so I'll do it some more, but now....hooboy...we have ridiculous power with the 200's😱

Re: Cleaning canister mufflers

Forgot to mention. Let the pipes sit for at least an hour or two before shaking and even overnight once the initial sessions have been completed.

Crock pots work great for nitro sized engines and mufflers but the canisters we are talking about here are generally around 16-24 inches long with tuned pipes closer to 3 feet. So unfortunately crock pots cannot handle this situation.

Would be interesting to figure out what chemical would work best. I am tempted to try Frank's method. I last did mine with a product called Industrial Purple from ZEP (Home Depot). Did the 5 gallon pail and warm water routine, filling the can's from the end with solution and letting them soak in the warm water pail for 30-45 minutes. Might have diluted the solution as per label instructions. Have to plug the bottom end of the can and it will bubble like crazy out the top. It is a messy job and as Lee said, use gloves and goggles and do it outside.

Need to soak them then rinse like heck to get the crud out then re-soak them a couple of times. Then rinse and rinse and rinse to get rid of chemical reside.

The only problem is that Industrial Purple degreaser is caustic and will oxidize the canister a bit and turn it steely grey instead of chrome. I was more concerned about getting the black gundge and crap out than what colour they turn as they end up buried in the bottom of the fuselage anyway.

I know a few years ago there was a thread on FG about cleaning can's and they recommended a Dawn BBQ Degreaser that was also caustic. I think it was eventually taken off the market because I looked all over Niagara Falls NY but could never find the same exact product.

Whatever you do use protection (eyes and hands) and don't do it in the kitchen unless you want to end up in the doghouse. The fumes are pretty obnoxious from a lot of this stuff.

Re: Cleaning canister mufflers

The Oxyclean tarnished the cans too but who cares. They are totally hidden from view except for the exhaust outlets. Could easily be polished if you were totally ----.

Re: Cleaning canister mufflers

Thanks everybody! I think that I will give Lee's approach a try. Easy to find the powdered Oxiclean and I just need a big bucket.

I'll also weigh the cans and headers before and after and report on the numbers

Re: Cleaning canister mufflers

Round one with the Oxiclean happened last night! There was a visible carbon/crud buildup of at least 1/32" in the inlet and stinger. LOTS of black gunk and black flakes were flushed out but I'm going to repeat the process at least one or two more times before this week's contest. I weighed the canisters and the headers before the treatment and I'll let you know after I'm done.

Re: Cleaning canister mufflers

You should be able to blow in one end without resistance when they are done. It was amazing how restricted our pipes were just by trying to blow air in them!

Re: Cleaning canister mufflers

Here are the results:

Before cleaning, the right canister weighed 467 g - after the second cleaning it weighed 455 g for a loss of 12 grams. Before cleaning, the left canister weighed 473 g, after the second cleaning it weighed 457 g for a loss of 16 grams. The left canister was quite a bit heavier than the right canister when I started and it was within 2 grams after I finished the second cleaning.

The headers also lost 4 grams each going from 162 to 158 and 160 to 156 grams.

The amount of chunky crud that came out of the canisters and the headers (even on the second soaking) was pretty incredible. I'm really looking forward to flying the plane this weekend!
