Engine cleaning options

Hey guys,

So I plan on replacing my valve cover gasket which has a small leak in it. When I do that, I want to take the pipes off and clean the font of the engine. What I am wondering is what is the best product/method to use. I have used Gunk foam degreaser on an engine not in a frame, but don't think it would do well with the painted frame right there. What would you suggest?

Also, what should I shove down the exhaust ports while cleaning? Just some rags?

Thanks in advance.
 
Simple Green works but it's not as strong as one of the citrus engine cleaners. Either way you are going to have to scrub with a brush if you want to engine to be truly clean.
 
In lieu of having some simple green, I once tried a SERIOUSLY heavy concentration of Dawn dish liquid and just a bit of water. Was pretty damn amazing. However, I have to say that a good motor cleaner is the way to go. I have used GUNK engine degreaser with great results.
 
Oh I'm ready. I've already picked up a gallon of elbow grease.

Does gunk mess with the paint?

Wow, very nice!!!
What other kinds of prep did you have to do? Did you have to pull anything off, or did you just gunk it as is and scrub?
 
Well, if you want EVERY nook and crany clean, there will be some parts removal in order, unless you are incredibly patient enough to get into each one with a bottle brush or whatever, and contort yourself into all types of positions. I clean my motors REALLY good once a season, and then just do a weekly upkeep. There of course is crud in the places i cant reach, but generally, i cant see those places unless im looking for them, so i dont care. If you want a THOROUGH cleaning, remove the pipes, carbs and tank, and scrub really well (DO NOT SPRAY water or anything near the open intake/exhaust ports) hook everything back up, and the hose away. Or...ask RenoBruce. He and Keith Krause probably have the CLEANEST GSs ive ever seen. BTW, THIS pic is a Gunk it as is and scrub, then spray, then break out the Mothers/Diamond Brite and hit up the case covers, and wax EVERYTHING.
 
Use plenty of PB Blaster on the ex bolts before trying to remove them....
