Residue on 1 of the Battery Connections

[gaz4d]

Hi guys,

The other day, i was refilling the screenwash reservoir.

When i lifted up the battery cover, I noticed there was a dry residue (oxidised substance) on one of the battery contacts.

Questions are:

1) What is this ?

and

2) Is it anything to worry about ?

It's nothing to worry about but you may like to clean it off after releasing the connections & applying a little 'petroleum jelly' (Vaseline) keeps a good contact ready for those damp starts in the winter (Remember you may need your Radio code) hth ........
