Ummm, why do you want it to be alcohol free? Not trying to start something, I really want to know the rationale.
All you are trying to do is get the water out of the system. The pink stuff with alcohol will do that. Once the water is out, you can safely drain the pink stuff out too. It doesn't have to remain in the system. The water is gone.

The RV antifreeze is either ethanol based or propylene glycol based. (Note that there is NO ethylene glycol in it. That is in car antifreeze and is deadly.) I am assuming that the OP is talking about avoiding the ethanol based stuff. However, technically, propylene glycol, also, is an alcohol.
