Is there any spray kind of corrosive tackle I can get, to clean the 'hard to get to' contacts, and rid them of the green doom, then wash off? I'm not scared of hard work, just thought there might be some easier way of doing it!

Alloy wheel cleaner, such as Wonder Wheels works well.

Standard electrical contact cleaner in a spray can.

Best bit of kit for your toolkit is a small file set, and a can of Ambersol contact cleaner.

make sure you clean both ends,

 

not just in the prongs,

 

but at the wires, where the wire goes to the connector.

 

my injector ones were so bad i had to buy new ones. the injectors are very fussy and need the correct amouont of current going through them

Yeah, I'll do both ends, I've just blagged a packet of very thin nail file emery thingies off my mam :-) they'll be perfect for the injectors, and I'll get a nail on the grindstone, and grind it to very fine point with a slight bend on it, that should do the job for the plugs, and I've already got a tin of servisol contact cleaner, not exactly a fun job, but I'm off to do it now, and I'll let ya's know if it cures the missfire, I'm pretty confident it will, fingers crossed!

 

Cheers guys!
