Prepping Valve Cover for PC

[supermech21]

Ok im looking for some info on deep cleaning a valve cover so that it can be powder coated. I know, i know, get it sand blasted and I said that too.The powder coater(V8 Redneck central) states he doesnt want to take a chance with the baffles under neath. So we had it hot tanked, didnt do shit. It even left the glue residue from the factory sticker on it ! Im trying my hand at the powder coating business and if theres something that I can do at my level(a soak or scuff pad) then I will do it. Ok so i tried:

Brake cleaner or de greaser and scrubbing with a wire brush(one that you would use to clean a golf club type)...didnt do shit

Soaked a sray bottle of simple green and the rest in water for 2 hours...didnt do shit

So a day ago i filled a container up with about 60% water and 40% simple green in a container, and then pre heated my oven to 200 degrees and left the VC in the oven for about 5 mins then submerged in the solvent for 24 hours. It felt a little bit more cleaner and looked a little cleaner but really didnt do much. Why I heated it up, i donnu seemed like a good idea at the time.

Is there a tried and proven method to get this valve cover 100% clean? A brush i can put on my dremel(that wont damage the metal but will last and not fall apart like other dremel head/bits)??? Any help would be great guys, going to heat the VC up for about 15 mins tonight and try another soak of 75% simple and 25% water for 24 hours submerged....

how 'bout instead of simple green use greased lightning. I'ts stronger than simple green and just use some good ol' dish washing soap to get that thin film that degreasers leave after ya use 'em. For some reason heating the V/C sounds like a good idea... go figger.

best idea is this...trust me on this i have done many vc's...
since the gasket for the Valce Cover cost almost as much as the Valve Cover itself, it is best to just buy a new VC and start from fresh, the finish will come out unblemished and you will not waste hours on cleaning and tons of money worth of cleaners.....

but if you are like me and are determined to use the original, mine is the original from my car and so is the gasket...
use a solvent like acetone in a cheap dish wash tub leave for a few days then spray it out with a water hose with high pressure to blast out all the crap then rebake in the oven for a while at 400+ degree and then let cool down and blow out with compressed air untill clean....
