Water Marks?

Folks,
Just wondering what you guys do when you find some water marks on negs after development (I used some wetting agent :) ).
Do you just run some water over the the negs again and leave to dry or whats your method ?Just dev’d my first two 35mm rolls from my ‘new’ Nikon F90x and found some water spots on the second roll.
Thanks!
jb7Participantwetting agent should be very dilute-
it should hardly produce suds at all,
by the time you’re ready to take it out-Its purpose is to reduce the surface tension of the water-
Eddies tip, using a squirty bottle of distilled water ( I use filtered tap water) is a good one-
It shouldn’t leave any residue at all, because there are no minerals dissolved in it-
Just spray your films before hanging them-
Water marks are usually on the film base side, not the emulsion,
and can be removed by careful rubbing with a lens cloth-
though this can get a bit tedious if you’ve got to do it for every one, every time-better to get the washing running efficiently-
And yes, you can just wash them again-

MarkKeymasterEddieParticipantI never tried the lens cloth but sound like a good idea, the fact you are dealing with a dry single negative allows you a lot of control and reduces the risk of damaging a whole strip of negative.
I have in the past re-washed negatives for drying and dust marks in warm distilled water giving them a light wipe with cotton wool. This is risky as you can make them worse maybe even scratch them. Sometimes the water marks don’t show up in he printing so have a go at printing them bofore you clean or re-wash them. You can buy the distilled water in a motor factors for about €1.50 a litre.BarkerPhotographicParticipantAvoiding them is the best bet, but when you do have them I find that using a soft lens cloth is the job, but it is a whole lot easier if you “haw” on the water mark first. Put the neg down on a clean flat surface as you clean and be sure to hold the neg firmly at both sides to avoid kinking it
MarkKeymasterFintanParticipantCotton gloves are a handy for a little cleaning like this so you dont damage the other side of the neg you are trying to wipe.
I think sometimes too much wash aid is worse than no wash aid so follow the instructions carefully.

Remember too that you should be extra careful even when using a lens cloth or tissue. Even the softest of cloths can act like sandpaper if you are over enthusiastic with it.
