Sanitizing it all is easy. I use pet bottles which when I've used them I clean and sanitise thouroughly and dump in a big box in a cupboard with the caps on and half an inch of no rinse sealed inside. FV next to the kitchen sink filled with hot water and more no rinse. 15 minutes before bottling dunk them all into the sink along with syphon, bungs, and other paraphernalia, swish it al about then stand the whole lot on the [also sanitized] drainer to dry. Obviously while doing this I'm getting my hands well and truly immersed into the sink too, splash it all about making sure everything in sight gets well and truly soaked and left to dry. Then just proceed as described. Been doing it as long as I can remember and never lost anything to infection yet.
Obviously the outside of the bottles get a bit sticky so there's an extra step at the end chucking them back into the sink and wiping them all down, but you get spillage and a bit of cleaning up at the end whatever method you use.
It's another advatage of PET bottles, you can chuck them about like this and dump them in and out of sinks and whatnot without too much care.
