I used bleach for 4 years for everything...until I had more stainless than plastic or glass items. I switched to oxygen-based cleaners and Iodine based sanitizers.
Now I am back to more plastic and glass...guess what I using again. Still the best way to sanitize removable plastic/vynil lines, racking canes and such...bleach in the PROPER concentraction with warm water rinses that equal about twice to thrice the volume of the bleach water.
Now get ready to flame me:
For sanitizing only, in proper concentration, rinsing within 5 minutes...bleach is approved AND awesome for sanitizing stainless. Ask anyone that has been in the dairy industry for more than 20 years before steam was the primary sanitizing agent.
