Sounds unnecessary to me, i just keep a bucket of starsan around all the time (keep a lid on it between brews, and typically swap it out every brew day) I keep a case of clean bottles in my freezer (cold glass foams less), pour a little starsan into a bottle, swirl around, dump and fill (with starsan foam in it) and cap. No problems
Don't take any more faith in anything I say than you would anyone else on the internet. If you listen to what I say, then hurt your self or break something it is your own fault, I am just expressing my opinion or experience.
THINK for your self!!
