..... You can buy a can of the battery cleaning spray to clean up the tray.
That would work but one can also just use some baking soda, spray things down with water and then sprinkle on some baking soda, which is a base to counteract the acid from the battery.
Note if the battery isn't more than a couple of years old it might just need a cleaning, you could always have it tested for free at many auto shops or parts suppliers, if it tests bad they might suggest you purchase a battery from them, you can always say you want to think it over and price shop.
Actually, I just noted the battery has a mfg date sticker of 1/18 putting it at about 3 years......I personally would just clean it up but it's up to you, expect to pay around $100 for a similar or $200+ for a better AGM battery like a yellow top Optima or another cheaper AGM battery. I've read Pep Boys have the 51R(if that's what your car uses) for around $150.
Upon a second look if it's a 1/16 mfg date I just replace it, with either AGM or a flooded acid battery like the Interstate you have now.
