Available from your local pharmacist or >pharmacy dept of the bit grocery store for next to nothing. . . . . I've been using Edwal LFN (Low-Foam Wetting Agent) for this purpose for about a bazillion years and I've had extraordinarily good luck with it. I have never--ever--had a water spot dry onto a negative (35mm, 120, 4x5) I've rinsed with LFN. Part of that has been, I'm sure, just pure dumb luck. But I've always held the conviction that a lot of it has had to do with the way that LFN is packaged. It comes already mixed, in a small plastic dropper bottle that allows you to squeeze out exactly one drop at a time, every time. So there's no screwing around with dilutions or finding a suitable way to dispense the stuff without using too much or too little of it. A single small bottle seems to last forever. I use traditional steel developing tanks and one drop in a standard 2x35mm-reel tank or 2 drops in a 4-reel tank, added to the final rinse and allowed to sit still for one minute, is all that it's ever taken. The film comes out of the water with no bubbles, without respect of water hardness or softness. I've considered using distilled water, just because it seems like t would probably be a good idea, but in fact I've had so much luck with simple filtered tap water and LFN that I've never felt compelled to switch. Now that I've written this, my next fifty reels will all be covered with water spots and unspeakably ugly crud, but the above does accurately describe my experience up to now. Regards Daniel Bowdoin
