Yo! I was wondering how you guys clean your engine bays, I don't trust the words I read on the interwebs.

 

I use P21S TAW and a brush, then dress all exposed plastics and rubber pieces with Sonus Motor Kote, and use a durable sealant on painted surfaces. I maintain by wiping down the engine bay after every wash with a polymer-based booster product to refresh the protection. Having the undertray in place helps greatly. I've only had to really clean the bay once; the rest is just maintenance. Try the detailing forum for more info.
