Clean the lens well, dry it, then take some good ole dishwashing soap.
Apply a thin layer on the lens, then just polish it dry with a soft cloth.
It should not fog up until the layer of soap is gone.

I got to try this and with the current humidity levels, it might be
soon. Dishwashing soap contains surfactantants that break up the
beading of moisture and spread the drops into a sheet that is easier
to see through, is large enough to evaporate, or maybe justs obeys
gravity and drips off.
