what i do is to clean the wipers thoroughly with a sponge/towel dipped generously in dishwashing solution. i also clean the windshield itself afterwards with the same solution.

don't use shampoo, even in a pinch. the stuff will clog up your reservoir lines and might even build up residue on your windshield.
I see, thanks for sharing your practice!!!
