Eclipse Cleaning System Solution
ECLIPSE lens cleaner is the highest purity lens cleaner available. It dries as quickly as it can be applied leaving absolutely no residue. When used with PEC PAD photo wipes, it is possible to clean only the portion of lens which is dirty eliminating  hazy swirls . Dispense several drops onto a clean, folded PEC PAD and lightly wipe surface in a single direction. Refold pad to expose a clean side and re-wipe as necessary. Other lens tissues may not work as well, and some experimentation may be required.
