To my disposal I have, wd40, trim blackener, auto gylm engine degreaser and a can of gunk. Try as I might I just can't get it clean. I daren't just spray the hose in there willy nilly.

I've heard all sorts like, plastic bags over the electrics, engine on, spray the cleaner everywhere, scrub where you can, hose off then dry and put trim blackener on the covers and wd40 on the hoses.

What does that sound like? Just want someone with experience to help me, and my dads only ever done land rover bay with no electrics in it and none of my mates are serious into car cleaning
