Thanks guys! Got a bucket full of StarSan sitting outside right now. Never thought about that so will try it first. If the StarSan doesn't do the trick I'll try the CLR.
I appreciate the tips.
All good beers have 4 things in common:
1. A good recipe closely followed
2. Good ingredients
3. Good sanitation
4. Excellent temperature control
Beer --- the reason I wake up every afternoon.
