I just removed my battery for some maintanace on my car and noticed this from my old battery for which GM should have cleaned IMO. My brother said use sprite and it will neutrlize it is that true or is there something else I can use.

Wow I just posted about my experience in another thread in External Engine having to do with this. Anyway, when I bought my car somehow i failed to see the horrible corrosion all around the battery area 
But yeah it corroded the coolant tube under the battery so bad I had to replace it. So good luck cleaning and do it fast before your engine bay looks like mine

Get a box of Arm & Hammer (or the store brand equivalent) and mix about half of it in a gallon of water.
Pour it on. Scrub with a wire brush.. Pour more on. Scrub. Repeat until the gallon is gone. Repeat as required to get the area as clean as you want. Rinse thoroughly.
This will neutralize the battery acid and remove the corrosion.
Dry the area. Sand to bare metal. Prime. Paint.

Coke / Pepsi are an old shade tree trick for freeing up
rust, the combination of phosphoric acid (read the
ingredients if you dare) and carbonation. Probably be
better off with a bit of Ospho (or C-L-R, Lime-Away,
etc.) and club soda. But for neutralizing I use baking
soda solution after first hosing it off real thoroughly.
POR-15 after that. Foirget the sanding and priming,
just brush it until rust stops coming off easily but no
need to get bright metal. The semi-gloss black in a
half-pint can will not stand out against the battery
tray and may be available atg local body / paint
supply places (it is, near me). Don't get any on ya.

On an episode of Discover Channel's "Mythbusters" they tested the Coke theory and found that it is only slightly more effective than water. You're better off using baking soda and clean tap water...neautralizes the acid and doesn't leave a sticky mess.
