cleanin inside of inlet manifold

[E30sid]

Quick question... just taken off my inlet manifold and i wanna clean the inside coz its got some build up of crap. But im not sure if i can jet wash the inside? can anyone tell me if this is ok???

Don't see any reason why not, there's nothing in there that can get damaged.

i find the best way is to get a metal brisle pipe cleaner from a hardware store to clean the runners. and carb cleaner. i don't think you can hurt any thing jet washing it just don't use to much pressure as i have seen those things crack brick if the pressure is to high.

I have tried jetwashing/steaming inlet manifolds out before and it just dosent seam to shift it very well, i ended up using brake/carb cleaner and a bottle brush
