Can anyone advise me please of th ebest way to cleaning loom connectors, ie cold start, knock sensor and the such.

I notice the plastic isnt smooth to make this job easier. Shoul i use a toothbrush with wd40 or not?

Its a spare loom i have bought to go into my motor once its al been braided so want the connectors to look right

 

toothbrush with wd40 will be fine mate thats what i used on my sapph and all plastics and connectors under the engine bay came up like new buff them with a rag to once you have cleaned them + WD40 wont harm your loom IE coroad(sp) it.

 

I can second this advice-it's always worked for me too

 

Started using carb cleaner too also very good.
