Micah,
I have had the pleasure or unpleasure of doing some of these type of repairs-First what type of granite is it-If it has been resined you may not be able to get the color back as the acids have destroyed the resin so try and determine that and let the customer know that fact.
Different granites or stones sold as granites may react differently to acid attack. If it is a straightforward unresined granite you have a better chance. Be careful how deep you go if the 200 doesnt get it.
If it is something exotic and colorful with a mesh backing you may want to test on a spare peice if you can get one.
 
Hey -just curious - none of my business but did he tell you how he spilled the acid on the countertop?

Micah,

 

You will probably need to start at a 200 or 400 granite diamond. This should be low enough to remove the damage.

Cover the whole counter with battery acid and it'll even it out and the customer will love you and the nice smell in the kitchen. Just kidding, if you're not comfortable honing it out the only way is to try a color enhancer and leave it with them because it won't last forever.

I have a client that spilled batterie acid on granite counter, it just made like a 1 inch area lighter/white than the rest. Any suggestions on the best way to fix?
