I will ask from the lab to give me a little bit of stabilizer.

Therefore, after loading the film on the reel, should I first immerse it in the water without wetting agent for a few minutes and then a final bath in the stabilizer mix before hanging it to dry?

Or maybe first try to "...remove the contaminants by gently wiping the non-emulsion side with a sponge barely moistened in distilled water"?
