I'm sure there have been nastier, but this K7100 is easily the worst I've come across.

After cleaning & ~12 hours of drying:

Getting something that nasty this clean is immensely satisfying. Who else has amazing before/after cleaning photos?

Wow thats a nasty looking thing! Sure cleaned up nice, what method do you use? For the ones i have worked on that were no where near that messy i used a paint brush and compressed air.
 
How did you clean it?

Warm water and the high pressure sprayer in my kitchen sink, then set it upside down on some rags to dry. There is still a little grime around the flyback, but it's so much better. I can touch it without covering my hand in dirt.
 
Use a hose.. Some simple green, or whatever cleaner you have.. Then dry in the sun..

Or dry in oven at lowest setting.. I've cleaned prolly 3-4 dozen this way.

dosent the water mess up the pots?
 
it's all about drying it properly. I actually wet an entire Sampo chassis, flyback and all once... not the brightest idea in retrospect, but it still works like 9 months later so it couldn't have been too bad. that would've been a good before/after candidate. I've come across some pretty nasty ones, like a K7000 from a Double Dragon cab (first monitor chassis I washed). the V1001 from my Space Invaders Deluxe was also pretty horrid.

I'm a huge fan of the simple green though, or the dollar store variety I buy, mean green. I generally use the hand dryers at work, but a hair dryer is sufficient too. otherwise you can bake in the oven, or if you're from Texas, you got the desert sun to use. :)

pull socketed chips out for best results so you can get the water out from under the sockets better (you'd be amazed at how much water gets trapped under those!), and since they're usually scarce and have no replacements in some cases, I would encourage removing the width coil and the flyback before you do anything real crazy.
