I was topping up the wife's screen wash today and noticed this




I've looked on the net and there seems to be a few ways of dealing with it, using baking soda, pouring coke on it etc. Does anyone know of a good way of sorting it so the corrosion doesn't happen again? I was told when a lad to coat the terminals in Vaseline, is there anything better out there?

I think some places use that white lithium grease spray, years ago Vaseline was widely used.

Hot water will shift the cack

Kettle of boiling water.

Thanks I will wash it off with boiling water then put some lithium grease on, I've got that at work, should be sorted in a few minutes. Black MY2013 SD4 GS Auto, Wood Company Armrest, Freel2 sticker.

Boy...
Sorry for asking, but when was the last time you opened the hood???

Its the wifes car, I was just filling the screenwash bottle. To be honest I cant remember last time the oil was checked, probably not since it was serviced in April. Black MY2013 SD4 GS Auto, Wood Company Armrest, Freel2 sticker.
