It's very likely you have a greasy/oily residue on your windshield and wipers from something. Sometimes car-detailing stuff gets on the windshield and makes a mess. Thoroughly clean the windshield and wiper blades with a window cleaner strong enough to remove the residue. Then try running the wipers with just plain water splashing on the windshield from a hose. If you still get smearing, repeat step 1. If not, try the solution in your washer reservoir and see if that's ok. If it leads to smearing, pump that out, clean the reservoir, and start over. Finally, if you still get smearing, try new blades.
