Kodak recommends 99+ percent isopropyl alcohol for the
_emulsion_ side of film but NOT the support side. It attacks the
cellulose. The best cleaner ever was Trichlor but its an
environmental no-no and difficult to obtain. I don't know what
Kodak's current recommendations are but you might contact them.
Likely different for motion pictures and still film.

Tim et al., it all depends on what they used to denature the alcohol. Methyl
alcohol will not leave a residue but it makes the ethanol undrinkable. Other
things can be used such as aviation gasoline, naphthalene (leaves a residue),
fusel oil (yetch!) etc., etc.

It has long been my habit to add a small amount of 91% Isopropyl Alcohol
to my Photoflo solution to promote more rapid film drying.
With Isopropyl so hard to get right now, I can I use fuel grade Denatured
Alcohol instead, or will the denaturing agents cause damage or poor drying?
