So, I brewed up Fruit Bazooka using Omega Tropical IPA yeast August 4. I fermented in my Glass 6.5 gal BMB and sealed it up. Tossed in the first dry hops 3 days later. . .then life happened. 
I didn’t get it into a keg until September 15 and when I checked the final gravity, it was 1.001. Red flag number 1. I saw no evidence of pellicle or anything abnormal (I brewed this last year and loved it), but I noticed a bit of funk when I drank the test tube sample. Red Flag number 2. When I cleaned out the BMB, I took extra care to scrub it out, and it’s been sitting full to the brim of PBW solution for two weeks.
The beer is not undrinkable, but definitely has some funky sour to it, doesn’t taste anything like what I made last year. It’s getting more prominent by the day. I’ll get through it cause I’m too stubborn to dump it, but I’m definitely pulling more of it than the actually good beer on tap beside it (Lakefront Fixed Gear clone, a summer staple at my house). My question goes to cleaning up after this apparent issue. I have a two tap kegerator. I assume I should fully fill the Keg with PBW and let it sit for at least a few days before dumping and sanitizing with Star San as per my normal procedure.
I typically clean the kegs when both blow, put some Star San in each, slosh them around, pressurize and push through the lines with CO2 until they’re empty. I typically have two new kegs ready to go by the time the two on tap blow, but life has been hectic with four kids lately.
About every 6 months or so (when I remember) I set up a pump to clean the lines with Beer Line cleaner solution and let it run for about 15 mins per tap, then pump clean water to rinse. If I do this, will it be enough to ensure whatever bug got into my beer won’t stick around?
