Any good ways to keep this clean? I work in a weld shop so my pants get all kinds of nastyness on them. And I have the grey inserts. Id like to clean up whats already on there (it isn't a lot but I notice it) and I will be wrapping a towel around the base at least for work. Anyways I want to get the seats back to factory fresh at the most so I can show it off. I already have other things to clean the rest of the interior.
