I like the idea of Iodophor or Paracetic as an occasional cleaner or on certain parts where I'd be most worried about wild yeast or mold hiding out (i.e. transfer tubing). I haven't had any issues, but I always worry about the silicon tubing I use to transfer to the fermentor as well as the vinyl tubing I use to transfer to the keg.
My typical cleaning regimen includes boiling for the silicon tubing and cam locks. Since I use a pump and I don't like taking my valves apart every brew, I end up recirculating boiling rinse water through all my hoses for 5-10 minutes after cleaning with PBW. Since I transfer my wort to the fermentor through that same loop, I clean and sanitize it like it's cold side. Same boiling regimen before I start the brew day (just a small amount to clear anything out before adding my strike water).
As it stands the boiling seems to do OK for the silicon. I just replace the vinyl every few brews, but with a different sanitizer maybe I could stretch that a little bit longer and feel a little less worried about some of the other parts by giving them a good soak now and then.
