Mirror factory has silver sludge forming on nozzles

Now I am an engineer at the mirror factory. We have problem on silver sludge especially when the temperature is hot. It appear under silver spray tips We use SnCl2 and PdCl2 chloride for sensitizing and activating We use two spray system process (silver solution & reducer) Anyone can recommend the method how to reduce those sludge?

Thank you,

I suggest that you contact the Merck Chemical Corporation in Germany. They provide chemical solutions to use in glass silvering which will solve your problem and which will also save you a great deal of money on silver due to improved plating efficiency.
