Advice - Cleaning gunk out of air inlet manifold

Hi Guys

I've had the air inlet manifold off twice recently (MAF problems) and cleaned it once with oven cleaner and once with Autoglym engine cleaner/degreaser and then Carb/air inlet cleaner.

It's still really dirty!!!

Can anyone suggest the best way to get it spotless inside?

I also think I may have moved cr@p into the MAP sensor inside it, so I am going to have to remove that and give it a clean next time I take it apart.

Just about to order a EGR bypass kit, which should stop it happening again!

Thanks in advance.

Hot water, washing up liquid and a brush, followed by pressure washer then put through the dishwasher when no one is looking. Remove all sensors before doing this though

As the thread by Ming - I used 2 cans of Mr Muscle Oven Cleaner. Just spray it in until the foam comes out, wait 10 minutes then wash out. I repeated this about 4 times. Inbetween used lots of kitchen towel to remove gunk as it started to move. Make sure you take the map sensor out first - clean down this hole with cotton buds.
good luck its a very messy job
