I have read the topic on this, but I was wondering if it is safe to use Optical cleaning fluids or prepacked sterile optical wipes on photographic lenses. My wife is an optical dispenser and uses these products on lenses for optics, but will they be safe on photographic lenses?

The brand in question is store branded (Spec Savers) and they use a pentax company owned cleaning solution that won't damage AR coatings.

Cheers.
