Re: Does cleaning solutions deteriorate lens/filter coatings?

I'm a photojournalist and most often I see lens damage because newcomers clean their lenses too often, often creating micro scratches in the multi-coating or allowing lens cleaning liquid to seep into the joint. A bit of advice:

1. Unless you see some serious grubbiness on the lens, leave it alone!

2. If you need to clean a lens, use a clean lens brush, then a microfiber cloth. (Personally, I just blow away any grit, breathe on the lens and use the cloth.)

3. Only as a last resort do you use lens cleaning liquid. I don't even own a bottle.
