A few weeks ago, driving from Longview / Kilgore, TX down to Austin.
I had to stop halfway to clean the windshield, and this is what it looked like at the end of the day.....
I had no idea that we were heading into this. A couple points we hit huge swarms and it was like driving in a heavy rainstorm just watching these huge black masses coming straight into the windshield.
Took me a good 45 minutes at least to clean the front cap and windshield off using plain water per my usual end of a driving day routine. I finish off the diamond shield using a detail spray and then will usually apply Griot's Bug Barricade.
I use one of my extension poles with an appropriate wash mitt head for the windshield and a heavy knapp microfiber cloth on the diamond shield. I use plain water when dong this daily cleaning of the windshield / diamond shield so I don't have to use a hose to rince off any soap etc.
