wetting agent?

Hello all. I keep reading about using a wetting agent after cleaning my sheet film.
Unless I'm just a tad dense I can't locate any chemical referenced as such. I've looked in all thge usual places, B&H Photo, Porters, etc. Is there some "technical name for a wetting agent?

Thanks for the help

Photo-flo from Kodak.

Rollei line of chemicals has the R3 Wetting Agent

Some vendors call it "film treatment" or some other name, but they all have it. The cheapest version is a couple drops of liquid dish soap (for washing up by hand -- Dawn, Joy, etc.) in a liter of liquid made of 7 parts water to one part 90% isopropyl alcohol. You can reuse this until it starts to grow mold...

LFN by Edwal is one of the very good wetting agents.

If all else fails, use one drop of liquid dish detergent in about a gallon of water. That is what I used when I could not afford any extra chemicals like wetting agents.

DON'T use Photographer's Formulary. As much as I love their products, that is one that has given me no end of grief. Too much and it leaves residue...too little and the negatives spot worse than if I didn't use any at all. The Photoflo works much better for me. I just hope it continues to be available.
