cleaning after corrosive ammo

It has been several years since I have fired/cleaned my M1 Garand. I have thousands of rounds of Korean ammo for it that I bought when we lived in AZ. Any suggestions on cleaning solutions?? I kind of remember someone telliing me to run a few patches with Windex on them down the barrel right after shooting, followed by a few drying patches and then some oil and then just clean normally when you get home, but that just don't sound right.
