Will your car start if you have corrosion that looks like grease on the battery terminal?

It could start but if it is indeed corrosion you probably want to clean it off. Somtimes people will lightly apply a form of anti-corrosion grease to battery terminals to prevent corrosion. Your typical signs of battery corrosion look like greenish or white stuff that will crumble away easily when disturbed. You probably don't want to touch it though a bottle of water and some old rags (where some protective gloves and/or wash hands thouroghly afterwards) that you can throw away, should clean it up. The battery terminal affected should be removed and cleaned to a shine with a wire brush for best results. Be careful working around battery terminals as not to short the battery it could be very dangerous. But yes battery corrosion will definitly cause a car to not start. I don't recall seeing it look like grease, that is unusual. Hope this info helps.
