	Just a quick one. Checking the battery on my girlfriends car as it struggles to crank in the mornings/when its not been used for a bit. Before hooking up to the positive terminal I noticed it had a milky residue on the pole and connector. I didnt touch it as i'm guessing its some form of battery acid? or is it something else? Positive milky stuff Negative Also this is the lowest the battery dropped to. I'm guessing with it being quite mild today it probably goes a little lower some mornings. I've started running the fuel pump a little before to help it a long. I noticed it dropped to about 11 something v when that kicked it before.

	That's just spray grease on the positive and general dirt on the negative. If you want to clean them you can use dielectric grease on them to keep them in tip top condition.

	It's just general corrosion. Clean the terminal and connectors, stick some vaseline on it and carry on as normal. Oh, wash your hands too. As to the voltage drop. Does it always drop to 9v? If so, I suspect a dead battery cell which would make sense with the trouble starting. Pop along to halfords and get it tested.
