What do you use to clean inside of intake manifold? I'm gonna be taking the intake manifold off real soon as I'll be putting a catch can system in. I want to make sure I get a fresh start with no oil so I was gonna clean the intake out as well, but wasn't sure what to use to clean it. I'm sure I could run some brake cleaner through it but maybe there is some other less abrasive stuff that works just as well.

Whatever you chose, doing a test spay on a small area to make sure it doesn't harm the plastic would be a good idea.
Make sure whatever you use, you read what it's safe to use on. Composite intakes are not like carbs or brakes. They're plastic and some cleaners may have an effect in the long run on the plastic.
well if you take it off you can use brake cleaner, if you leave it on then I would suggest deep creep by seafoam. It has a nice long straw that you attach so that you can get a little deeper in the intake.
Look at the sticky in the general maintence section about seafoam and it will go into a little more depth about it.

The used LS6 intake I got through eBay was not cleaned before shipping. Sand/dirt on the outside migrated into the ports during shipping. I cleaned mine with lots of Simple Green, a toothbrush, and lots of hot water in the tub. Seemed to work good enough. If I had to do it again, though, I would use Simple Green and a high pressure washer. Good luck.

If the Intake is still on the car.. Seaform Deep Creap..
If its off.. almost anything will work. but I use Castrol Super Clean, let it soak, followed up with a good cleaning with soap and hot water with a quick blow dry of compressed air.

Brake cleaner on blue shop towels works rediculously good. It cuts the oil like nobody's business and then evaporates. Take 2-3 sheets of towel, blast it with brake cleaner, put it on the end of a screwdriver, and you can get all the nooks and crannies your hands wont fit into.
Carb cleaner leaves a bit of an oil film (to lube the carburator pieces a bit), but brake cleaner leaves no evidence.
I think the simple green is a bad idea. Oil + water = never ending mess.

Alrighty then, brake cleaner it is. I'm a bit leery of shoving a towel in there and have some small piece get left behind where I can't see it. I'll play it by ear though.
Another vote for brake clean...that's all I ever use. On the car I use red cloth shop towelswith brake clean and /or off the car spray the heck out of it and then turn it on end and let it drain the excess out.
