I know i've asked before, and i know there was a decent guide on it but cant find it anywhere

Anyone good good tips/methods/step by step guides on what to use and what not to use on and in your engine bay?

When I did mine I put a plastic bag over the battery didn't need to over the filter as I have a cias. Then have it a light spray with the jet wash after that sprayed the full bay with megs engine degreaser and aggitated it abit then another light jet down to rinse it dryed as much as possible after then put engine on ( take bag of filter first ) and keep runing until dry then dressed with bare bones job done

Found a good guide on DW. Ill find i for you Jack

Bare bones used it on pats focus st and Alex old st and used it on mine loads of times it realy is fantastic stuff, just spray leave for a few mins then wipe it realy is that easy if you have a realy dirty bay then it might be worth going over it twice just make sure you a loads of rags,

Also maybe worth a light spay with the jet wash just make sure you cover the coil pack etc etc
