All joking aside, I used to stop by the car wash on light pickup days, put all the packages on the top shelves and wash that baby out from front to back. The cab got it several extra times during the year as well.
And no, did not do it on my lunch or break. After they griped and complained a while, they started getting the car wash to do each car at least once a month, and the ones on the really dirty routes twice or more.
Your center manager would be the one to set the tone for the car wash. Bring it up as a safety issue to the safety cochair, even attend a meeting to present your problem.
If you dont take a position on this issue, it will never fix itself.
