I had a c-section last baby(#9), and it also got infected. The nurse gave me great advice. She said to blow-dry the area, and then put a pantiliner on my underwear(stuck to the inside) to absorb any moisture. Just make sure they aren't deodorant ones. It worked well, and I healed nicely after that.
Hope this helps!
