Changing a car battery

I’m trying to replace my car battery but old battery acid has covered
the negative terminal.  I have wiped away the excess acid but it has
gotten in the ridges of the screw, causing me to have a hard time
unscrewing the nut.  Any help or suggestions as to how I can unscrew it
without stripping the nut in the process??

Thanks.

    Many auto parts stores have little wire brushes that can help you clean off
    a lot of that mess.  You can wash it off with fresh water with bicarbonate
    in it
    (to neutralize the acid) as you are brushing.

    They can also sell you a new bolt and nut for the terminal in case the old
    one
    is so corroded that you wont wish to re-use it.

    Be sure to clean the terminals well before installing  new battery..
    I dope them heavily with Vaseline to slow the buildup of corrosion.

     You are scaring me with your question. Wear eye protection and don’t
    get any of that acid in your eyes. Make sure you get the polarity right
    when installing the new battery. I’m not worried about the screw
    threads because they will clean themselves up when you unscrew the
    terminal. Wire brush everything before reinstalling. And always remove
    the negative terminal first and reinstall it last. That way if you bump
    your tool on a ground while working on the positive terminal you won’t
    have a big short.

    With security systems and codes to prevent car radio thefts, replacing
    a car battery can be a lot more complicated.  Please see Section 8 in
    the Car and Deep Cycle Battery FAQ in http://www.batteryfaq.org for more
    information on installing car batteries.  Vaseline and other petroleum
    jellies have a low melting point and might not provide much protection
    with the high underhood heat that is experienced in most cars.  A high
    temperature wheel bearing grease of silicone will work much better.

    Kindest regards,
