Last week in Chicago it rained the whole week. On my way to work (last week), I noticed that my 5-month-old Bosh wiper blades where skipping/jumping on the windshield (very annoying). So, the next day I cleaned and clay bar the windshield. The very next day, the wiper blades were still skipping/jumping on the windshield. Today, I put new ones on, and these damn brand new (OEM) Bosh blades are still jumping/skipping on my windshield. Is there any reason to why they’re not gliding or functioning as normal blades do? I don't use any windshield treatments like rain-x defogger or other stupid products.
