I am also living proof that doing nothing at all results in perfectly fine negatives.

How do you expect removing excess moisture is going to protect you against cat hair or dust in the air though? The film is saturated with moisture and will be tacky until it isn't tacky. The surface water, which is gravity drawn, isn't going to massively change the equation when it comes to the core removal of moisture from the film. Even if you used a completely lint-free cloth, wiped off all excess moisture (ignoring the possibility of scratches), any dust that shows up is still going to adhere.
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
