How long is Zero active in cleansed sprayer?

I have used Zero to kill weeds and it has worked well. My question: Can the sprayer - container, hose and nozzle - if all cleaned well with water and left to dry, be used to spray non-toxic liquid, like water?

Plastics retain residues, even after thorough washing, so best practice is to keep one sprayer for your herbicides such as Zero, and another to apply fertilisers and the like.
