Dirty, dirty lenses

[papi]

i have had just about everything on my lens.i carry a small container of glass cleaner and some wipes.not true about it taking up space. all together it is about the size of a cigarette packagethe other person ask how to keep them clean and you only said in the field.good glass is a must. scratches will indeed cause problems if bad enough.it will cause a haze in certain area.i also have good glass. i have a x-111 leupold,3.5010x50. it has a ill german #4 dot. also have a swarovski 4x12x50.they are both good glass.the same goes for binocs.i have the leica 12x50 binocs
