I just purchased an old aluminum intake manifold, decent shape but it has some carbon buildup. I looked online and I've seen everything from basting crushed walnut shells to over the counter cleaners to oven cleaner. Anybody here have hands on experience? What works for you?

Delco combustion cleens.
I get it at a GM dealer parts counter.
If that does not work, I drop off the intake at local machine shop and pay 20 bux to get it hot tanked when they fire it up to do other work.
Hope this helps

Not that I recommend this...
My best friends Dad when we were growing up, owned the Chrysler dealership. Every once and a while I'd be over at the garage and he would be "out back" with the acetylene torch and a screwdriver or a big wire working on burning carbon deposits out of an intake manifold. Man the pops and bangs and chunks flying made it dang interesting to watch.....
