I would recommend a thourough rinsing with water since you probably can't paint until it is warmer anyway. I don't think a simple wiping would clean off the residue of the purple cleaner. If you have any exposed metal from the wire-wheel treatment it will flash rust immidiately so you need to rinse/wipe down with denatured alcohol as a final cleaning on all surfaces. Just my opinion, worked for me.
