HI,
I was wondering how long to keep Sensor cleaning fluids before discarding them.
I notice that all chemical liquid products have a shelf life, so how long would you keep on using them for cleaning your sensor?
My lens cleaning fluids (Kodak) Yes still using that product. I notice after about 3 years from purchase date that it smears more, so after 2 years from purchase date I discard properly of course and I replace with a new one.
How about Sensor cleaning solution, open or not open. How long?
