Temperature about 20c and about 50-60% humidity , i dont squeez or blow(i think blowing can be risk if dust sits on wet film) , i shake the negative well for the excess stab to go away , i use Fuji kit .
I leave them 1-2 min top , soaking first sounds good !
i get some light milky marks that rarely apear when scanning (i am not sure if they reduce sharpness thought) and they are easy to clean so its not huge problem !
when squeezing with fingers you first dip them in the dillution ?
