What is the best product to use when cleansing after a breast reduction?

I'm 8 days post op and have been cleared to shower/bathe. I was wonder if there is anything specific I should look for in a body wash or cleanser or if I should even use something like that? I've just been running warm to cool water over my chest but I'm concerned that isn't enough. I don't want to slow my recovery process down and risk an infection because I'm not keeping the area sterile enough. Any advice would be greatly appreciated.
