I think if you maintain your condensate drain by pouring hot water down it once a month or so, then you don't need to add any other chemicals since it will be basically clear of any algee or other growth. There will be nothing to "wash" away. But if you haven't maintained your drain and now decide to do it, then you probably want to flush it out with some soap or mild chemical to get it clean.
I'm surprised that no one has mentioned this device. Anyone using it? Once you by it for $99 then it's $44/year for the solution.
