What can I do with granular citric acid?

I want to descale my OXO Barista Brain Coffee Maker, and I understand that OXO brand descaler is essentially citric acid. It's also very pricey. The buy-in-bulk price points for granular citric acid seem too good to pass up. If I buy a 5lb or 10lb bag of granular citric acid to make descaler on the cheap, what else can I do with it?
