You can try to clean it off with a wire brush and white vinegar. It looks pretty bad though, I'd make a trip to the dealer and get a new part. Then when you install it spray some of corrosion preventative on the exposed metal. Here is a link to one product but I'm sure your local auto parts store has it or something similar.

Clean it up good then you can use anti-corrosion washers or [anti-corrosion spray](https://www.amazon.com/Permatex-80370-Battery-Protector-Aerosol/dp/B000BOKML2/ref=sr_1_2? s=automotive&ie=UTF8&qid=1496404545&sr=1-2&keywords=anti+corrosion+spray) or just coat them in a heavy grease after you retighten.
The corrosion is caused by the dissimilar metals and perhaps a bit by the hydrogen gas generated when charging the battery.
Baking soda + water are great for clean dirty car battery terminals.
Disconnect the negative battery cable, then disconnect the positive cable.
Make a slightly watery mixture of baking soda and water (filtered or distilled is recommend), and carefully pour the mixture onto the battery terminals; Be careful not to let the water touch both terminals.
Using an old toothbrush or wire brush, scrub the corrosion off the terminals, then rinse with filtered or distilled water.
With your terminals nice and clean, repeat the process on your battery cable connectors (it might be easier to soak the connectors in a baking soda solution instead of trying to pour it).
apply either battery terminal protector, Dielectric Grease, or a thin layer of [protroleum jelly] (http://www.amazon.com/Vaseline-100%25-Petroleum-Jelly-Ounce/dp/B007E62538/ref=sr_1_cc_2?s=aps&ie=UTF8&qid=1374477009&sr=1-2-catcorr&keywords=petroleum+jelly) to the terminals of the battery.
Reconnect your positive terminal, then reconnect your negative terminal and you're all set!
I've never understood why people think that pouring Coke, which has phosphoric acid, is supposed to clean up battery corrosion caused by sulfuric acid. Scrape off the corrosion, dump a bunch of baking soda on there, let it sit until it cakes, and scrape that off. Wire brush clean. Keep your terminals as sealed and dry as you can. They make spray to keep the terminals protected. It works wonders.
Use some baking soda and water (spoonful to a cup), let it work (3-5min), then brush with a wire brush. Then remove the terminal and repeat on the terminal and the battery post. Grab some battery terminal protecter and give it a nice coat. Following these steps takes a little more time, but is the most thorough and longest lasting method I've come across. Cleaning the outer surface before removing helps your wrench get a better bite when removing pesky terminals.
Probably this stuff. Most of the reviews say it dries purple.:
