The front two mats on my '99 EX V-6 are so horribly riddled with stains (mainly on the passenger side; looks like gum and some other pollutants have ravaged this mat with large black stains from something someone spilled in the car or dragged in) that I am considering just replacing them with two new ones instead of getting them cleaned or trying to clean them.....is there a site I can order stock sixth generation front ACCORD mats from (in the beige color) or is it best to try and shampoo these stains first and get the stains out?

Thanks in advance for any guidance, friends.
