While all great options (esp. the wall hangers tray), when racking to my keg I've been simply using my spray bottle of star san. Spray down my hands. Spray the outside of the tubing. Put the nozzle up to the tubing and spray in a few squirts and shake it all around. For the siphon itself spray down the outside and inside well. Swirl around as needed and dump out the excess. Assemble the tubing to the siphon, loosely knot the tubing to keep it up and out of the way while I do other things and clip to inside of the fermentor. When ready, bring the tubing to where I want it to go and I'm good.
During brew day I usually have a bucket of star san handy, but not so much when I'm just doing some utility brew tasks such as kegging, etc. I've had great success with it. Now I use my wall hangers tray to store all my clean long items and misc items like racking canes, hydros, spoons, paddles, airlocks, etc.
