I don't know about Kodak products availabiliity but to check for residual silver on a print you can use a simple solution of Kodak Rapid Selenium Toner and water.
Place a couple of drops of KRST 1:9 on the emulsion in a clear area. Let it sit for two to three minutes and squeegee off. There should be no stain. Residual silver will be apparent as a fairly dark yellow or brownish stain.
You can do this after fixing or after washing, but before toning. |
