i just used water, old tshirt, and some armoral whipes.

I used the Gunk Gel engine cleaner. Used an old beach towel to cover the interior. Sprayed it with gunk, let it sit 20 min and then washed down with warm water, being very careful where I sprayed. Let it try a full 2 days before I fired the motor again (for electrical reasons).

Wish I had thought to take some pics! It does look brand new though now!

I've used Gunk on engines - transmissions previously. Works great but stinks for a few days while the chemicals burn off. A better route is S100 although more expensive. Access a cold engine, spray on, and hose off. Electrical issues should be of no concern as your engine sees worse conditions when being driven in inclimate weather. Have cleaned motorcycles and cars for years in this manner with no issues.

The S100 is an excellent product. I have found the key to not having a smelly engine with the Gunk is to thoroughly rinse it down with clean water. As to electrical issues, I have also let things dry completely before firing (friend of mine had one bad experience once that cost him a new alternator).

Haven't cleaned the Boxster engine yet. On my other cars I used Orange 409.
I warmered up the engine and the turned it off. Sprayed Orange 409 on all the engine parts and let it set for 10-15 minutes. I then rinsed with a gentle stream or water from the hose and wiped down with rags. Work great and much cheeper than Gunk.
Anyone try this on the Box?
