I have found that a side benefit to Rain-X, is that it removes the wiper blade line. This is the original stuff, in the small bottle.
Apply it per the directions, and as you are wiping it on, you will notice the wiper line disappear right before your eyes.
If you are talking about wiper marks that are so bad, it appears as wear on the windshield, nothing is going to get rid of that. But if you are referring to nothing more than an arc on the windshield, then Rain-X is the answer.
