… is far less trouble now that I’ve applied this stuff:
www.nu-screen.com
…which is advertised for iPods, iPads and iPhones, but “works a treat” on my cameras as well. Heck, I’ve even used it on my eyeglasses.
(It repels oil, such as from your fingers, or cheeks, and at the very least, makes cleaning it off with a soft cloth, far easier.)
I’m very happy with my purchase.
YMMV, but HTH! 🙂
