I only know about one old-timer: My Dad, vintage 1915.
He had a well-worn, frequently laundered, 100% cotton, handkerchief in his pocket. When needed, the hankie came out, he breathed on the lens (with mouth open, to help prevent spit on the lens, and to fog the lens a bit), then polished with the hankie. That was the hankie in his left pocket.
He also had one in his right pocket, which was actually used for the purpose hankies are made ;^)
I would never use a 'hankie', no matter how well laundered. It may feel soft to the touch, but actually too harsh for the lens. Magnifying the lens coating will reveal thousands, millions of tiny scratches over time and reduce IQ.
When I purchased my first SLR I used my 'shirttail' ... 'Scratch' (pun intended) one lens. My history is not learning on the cheap.
The best advice has been given. Use a filter and only proper lens tissues, and only when necessary. Proper lens cleaners only when absolutely necessary.
My preference is either an UV or NC filter. When I buy a lens it goes on and only off when absolutely necessary. Usually in poor lighting conditions. Then it goes right back on.
I know in the past several HOGs have expressed their dismay about using a filter; however I think that is a relatively inexpensive way to protect the lens. Then if you use the 'hankie' on the filter you only need to replace the filter every so often.
Just my opinion. Vinny
