    Hi

    Tried to start my car this morning after approx 9 days of inactivity and it wouldnt start.

    Looked under the bonnet and there was a bluey substance on one of the connector (not a lot but noticable)

    Probably needs a jump start but should i be worried about this substance or is it natural?

    Tks

    Sounds like copper sulphate. Usually caused by overcharging. Have your battery and charging system checked as overcharging can damage a battery.

    Use boiling water to wash the stuff off and coat the terminal in Vaseline to stop it reoccuring.
