Sorry it took me so long to reply. I'm just getting settled from moving.
It's hard for me to say how it turned out as I never actually brewed that cerveza since. I can tell you that I did drink it all and it wasn't off-tasting enough for me to stop drinking it. It was a light beer to begin with and I didn't have as much starsan as you so all I can say is that if I did the same thing again I wouldn't be worried about it.
Sorry if that doesn't help you.
Let me know how it turns out if you decided to go with it.
