Does anyone have a good method to clean work truck plastic flooring?
I have a contract to clean and maintain a fleet of work trucks. Some have the dimpled plastic flooring rather than carpet.

I tried several methods to clean the floors. I blew out the floors with air. I tried Optimum no rinse, degreaser and Meguiars all purpose. I tried a brush, mop, vapor chief steamer, and then the steamer brush. Then I even tried the pressure washer. i quickly blew the water out of the cab with air.
This is the best I could get:

Backseat

It's good enough for the price I am getting paid for these vehicles, but not good enough for my individual customers in my opinion.
If you have any tips I would appreciate them.
