Washing Your Prints!

Thu Oct 11, 2001 9:27 pm

Hi all

Something for the experts.

Anyone washed their prints with water and detergent?

I came across a magazine article today and basically said this was ok to rid the print of marks etc. Even showed a picture of someone washing the print.

Advice??

I used to use "photoflo" which is like a soapy liquid that helps rid film of water spots when I used to develop B&W negatives. I would put a drop or two of photoflo in a shallow tray mixed with water and move the print around in there for a few seconds and then I would use a squegee (like the kind a Gas Station uses on your car window) to move the excess water off and then either airdry or use a hair dryer.

Gary,

thre should be no problems washing prints if they are dirty or have marks you wish to remove - the final stage in the printing process before the print is dried is washing.

Ilford make a product similar to what Mark has mentioned - I think called "Ilfotol"? - it's referred to as a wetting agent - and stops drying marks on the surface of the print as water evaporates from it. Alternatively, you could use a VERY WEAK solution of fairy liquid, which has a similar effect (not quite as good), but you probably have to hand. Paterson make a print squeege to remove excess water and aid drying - but you could lay the print flat and use a window cleaner's squeege (but make sure it's CLEAN - you don't want scratches). Squeege-ing the print before leaving to dry will drastically reduce the drying time, and also reduce any drying marks you might get.

A word of caution - some marks and debris on the surface of a print could actually damage the emulsion. In this case, it might not be obvious before you start, but washing the print would remove the marks AND the emulsion that's underneath them! I would say this is the exception rather than the rule - prints are pretty resilient if they have been properly processed in the first place, but I thought it worth a warning note.

Gary,

I use Kodak PhotoFlo 200 to wash negs and prints. I believe the product is a simple wetting agent
and the recommendation is to dilute it. As I recall that was approx. a capful in a gallon of water-very scientific!

It does a great job of drying the prints without water marks. Do take note of Fwoggies remark about not affecting the emulsion. If you have prints that have had debris dry onto them, let them sit in the solution 15-20 minutes. Then slowly and lightly wipe your fingers across the affected area while the print is in the solution. This should loosen the debris rather than tearing it and the emulsion away.

All this talk makes me want to get into my B&W dark room one of these nights. I haven't used it in a couple of years. I do have quite a few B&W airliner negs I could print up, but the hit counter on my uploaded prints shows the B&W stuff doesn't get much attention.
Then again, so what?

Would this work on colorslides too?? I had a few films that were messed up by the lab and was full of spots.

Staffen,

The color slide cleaning solution I have seen was apparently pretty potent chemistry. By the time I was done reading all the warnings and possibilities of ecological damage, I was glad it wasn't my property.

I have not had good luck cleaning slides. It may depend to some extent on the type of emulsion involved. If you have a spotted one that is replacable, experiment with Photoflo or dilute liquid detergent soap and see what happens. Unfortunately I don't think you will be satisfied.

Anyone else got the latest on successfully cleaning slides at home?

Hi Tom

Thanks for the info.

But hey, stuff the 'hits' counter. Let us see your old B&W stuff. I look at them anyway  Smile
