Sand/Dirt In Front Windows

Hello,

We've had non-stop slushy/wet snow for the last few days and today going to work (with all the build up of grime on the roadway), half my truck was splashed by an oncoming semi. Had to roll down the window to enter the parkade with a pass and noticed the sound of sand/dirt rubbing the window from the inside of the ‘rubber sills’. Any ideas of how to clean this out completely? Not rolling down the window for the time being is not an option as I enter the parkade everyday.

Thanks in advance!

i get sand balsted all thhe time being on the beaches out here...
i just rinse it off with water.......

 

i usually just bend the sill back and run my fingers across it till you dont feel the grit and grime on it then you should be good to go
