Rubbing alcohol about 1:5 with distilled water. You want
the same 'tearing' effect you get on a glass of a ~15% or
greater alcoholic drink.

When I process my b&w film I have very bad water spots. I
am unable to
get to a photo store (or order online) at this time. Is
there a home
made remedy for this problem? Photoflo worked previously,
but, I am
out. Thanks -- Jeff

Sometimes water spots can be fixed by soaking the film
for a few minutes and squeegeeing. If there are rings around
the spots they are minerals from the wash water. The rings
can often be removed by soaking the film in stop bath for a
few minutes and re-washing.
I don't know a good substitute for Photo-Flo except other
wetting agents. However, you might have luck by using just a
drop of liquid dishwashing detergent in water with about 35
ml per liter of 70 percent Isopropyl alcohol. This is common
rubbing alcohol. An excellent final rinse is made by mixing
about 35 ml of rubbing alcohol, 2.5 ml of Photo Flo and one
liter of water. If you use detergent a tiny amount is
needed. I think the streaking you got was from using too
much. The alcohol should also help prevent streaking. When
using the final rinse just hang the film to dry, don't
squeegee it.
