There are some practioners who use very gentle sponge, fingers, and various specially made squeezees for this purpose.

I used to use my own fingers. But I stopped because it wasn't necessary at all.

Wet film is VERY delicate and it can be scratched easily by small dust particles or whatever might be on the surface. Wiping is not necessary for drying mark free negatives. If you use Photoflo type solution at correct dilution, the water droplet will sheer off the surface all by itself.

Incidentally... correct dilution is NOT what is on the label.... in many cases, including my own, using what's prescribed will result in dry mark CAUSED BY photoflo. I use half of that dilution. What's right depends on your own water quality so you'll have to experiment yourself.
