Other than a good cleaning of the glass, one situation where the high $$ defog actually does a better job - for me at least - is with the plastic stick-on magnifiers. I tried Sea Drops, 300 PSI, spit and baby shampoo, and none of those kept the lens from fogging. As a last ditch I tried Sea Drops Gold, and that kept the plastic lens from fogging.
