Well, the ones in my Blazer were also made by Plasticolor with molded color, but the molded color was only skin deep. It's been a few years though so they may have changed their process since then.

'Vibrant colors are molded-in so they will not fade, wear or wash away'

With advertising like that I'd take them back and exchange them for new ones since the color obviously faded.

 

Those are some really nice mats....

I have some full strength purple power that I use to get the stains off my camper (its white)and works great!
Most camping supply stores carry it! That should work!

Its great for cleaning and getting stains out...

 

It does 'look' like its a solid piece of coloring, I've seen with the mudflaps (same company, same materials) one of the logos was chipped/cut and the color did go through.

 

I once did a test at work with purple power & superclean. both do the same stuff, smell the same, work the same, just labeled different. Oh, same colors too.

 

Its what I recommend...
But what you get at the autoparts (purplepower) and what I have from the camper store same name...but different strengths...

Its recommended from the camper store to "dilute" it down...
Thats why I recommended it... its your call... of course.
But I have had great success with it so far. Its mainly used for the rubber roof on campers....which you may or maynot know gets all kinds of weather stains,bird poop,tree sap, road tar etc. etc.

Just FYI.
I havent used "Super clean".. so I wouldnt know anything about that brand..

 

I was using the stuff full strength, and the stain didn't budge...):

 

I know you said you tried that wesleys bleach white (which I think is a great product for white letter tires...)

Have you considered trying straight bleach? Or mix straight bleach with tide laundry soap? .. My mom made me scrub floors whether it was lonoliem,ceramic tiles etc... and it always did a great job....

 

Soft scrub gel w/bleach might work. You could also try bathroom cleaner(the scrubbing bubble type stuff). If nothing will work you could just buy a new set for summer and keep this set for winter.

 

Great advice Lou!

wish Id thought of it lol

 

yea, I tried wesleys. A little dissapointed it didn't work.
