What I've found about reconditioning these mats is that it can turn them into ice rinks. Look good - hazardous under foot. I hate 'em. They keep the winter crap off the carpets but can't wait to swap them out come spring.
another reason to avoid Weathertech floor liners. I'd like to see the result on those beige liners in your wife's car. I have those and they're impossible to clean. The stains do not come out whether pressure washing or using high grade commercial cleaners.
Why overpay for that liquid spray when you can get way better results with Maguire's Trim Restore or better yet use the classic never fails "Pledge" (less than $3), it leaves a matt shine dust free and dries quick. Want to better protect them for life looking new for years then use the unbeatable "Aerospace 303 protectant" (less than $9) and its amazing on everything ... *** I use 303 on my kick ass 3D MAXpider custom mats for my BMW 5 series F10 and they just don't ware out!
So this Renegade Rebel stuff is like Armor All in a sense it doesn't really get the dirt out, or that applicator would have been dirty, it just puts a bright film over the dirt. That would seem like it would build up over time with all those layers.
I am very much aware of that but it shouldn't be that hard to clean these things for the money you pay for them. A clear coat of a polymer, like that used on basketballs which has a similar surface as these mats, would prohibit dirt from setting up a home in these things. For the price you pay for them a little more technology would be worth the little extra cost. To sell a product that you need to clean the surface before you apply it just seems counter intuitive.
