how do i clean my progressive plastic lenses and frames

[refuge821]

We use plain hot water.  As for a cloth, we use what comes with a camera or binoculars for the lenses.  The eyeglass place recommends a micro-fiber square but I like the idea of the one for the lenses better.  Don't use anything with alcohol since it wears away on the finish I am told.
