Default Clean the Plenum

What/how does everyone clean their plenums, I want to clean mine before I put it back on the car and the inside is pretty dirty and the small passages have some carbon inside, I was thinking about having a machine shop put it in the hot tank, is this a good idea or will it ruin or warp the plenum ?
Thanks.

As long as the plenum is off the car 2+2 carb cleaner works great. leaves the plenum with a new look

Machine shops have a cold tank for aluminum and similar :thumbs:
Cleaner in a can works good. I used a bottle brush on my runners.

Took mine down to TPIS to have them hot-tank it, ... turned out good as new. :)
