Keg Do's and Dont's?

[Beer-lord]

Can't say it makes much of a difference but I have read that BLC (line cleaner or the like) actually inhibits possible mold or other growth on beer lines better than PBW or Starsan. I've had the same bottle for 2 1/2 years and likely enough to last another 2 1/2 years and clean with each keg. My kegs usually last me 2-3 months on average so it's not a problem doing this each time.
