No matter how hard i try they get so dirty so quick.they weren't cheap lenses either they were 200$. i clean them with the cleaning cloth they give me i still cant get them clean 100%. i run them under water and clean them but then they get dirty immediately. and they take forever to clean.i used to have nikon glass lenses and they cleaned up like a charm, run them under hot water and wipe them off and they were good.any ideas
