Best is a wire brush and baking soda. You can use grease to coat the terminals to slow down the corrosion.

What are the blue crystals on a car battery?
Corrosion from the sulfuric acid. The electrolyte (water) inside the battery is a mixture of sulfuric acid and water. Those blue crystals is just corrosion. You need to clean it off. Remove the negative black (-) cable first and then the positive red (+) cable. With a mixture of 25% baking soda and water, clean all this corrosion off the battery and the cables. You can also use vinegar. Dry everything off and then clean the connections with a battery post wire brush you can buy at any parts store. Reconnect the battery cable positive first then negative.

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.

Car won't start unless it is jumped with cables?
Sounds like the battery needs to be replaced if it is old or the connection to the battery is lose and needs tightening. Is there corrosion around the circular connectors on top of the battery? If so, clean it off and consider replacing them if needed. That's my best guess.

You just have to reset you radio,clock,etc.
