Great job on cleaning the bay, what did you end up using? did you pressure wash/steam clean or just wipe down everything with a particular product
I used deb traffic film remover sprayed it on left to soak for a while and just hosed it off I removed the airfilter so it didn't get wet and covered the air intake up with a plastic bag and a rubber band so the inlet pipe stayed dry
Then air lined it all off, paying extra attention to coil packs etc run the engine till it was all bone dry and dressed the bay with concept PVC sheen
