Remove hard water stain from Eye glasses

The other week I noticed my eye glasses had dried hard water stains on
them. This seems to have accumulated over time. My lenses are glass
lenses (not plastic). I thought that the lens cleaning solution you
get at the optical stores would do the job - that did not help. Also
tried vinegar, but no success. Is there any to get rid of these dried
stains. If not, the option is new lenses. Appreciate any advice.


Thanks.

 

If they are hard water deposits, then soaking them in vinegar would
absolutely take them off. If you've done that, and they haven't gone
away, then what you may be looking at is etching. Basically, very
fine scratches that accumulate over time, and give a fogged
appearance.

 

maybe you should try some clr?
