Stupid me, I left my new Chevrolet Racing floor mats in the car during the nasty snow. Now the driver side mat's lettering and checkered flag is no longer white and now has that nasty yellow stain.

I've tried superclean, got the mat clean but not the stain.
White wall cleaner (wesleys bleach white) didn't work at all.
I even tried a can of salt eraser and it didn't work.

Got any tricks?

 

blue magic has done me well, let it soak and then use a floor cleaner to spray it and suck it up

 

That stuff is good for rubber?
-edit: I'm not too big of a fan of blue magic, the trigger that is used on the can doesn't spray evenly..

 

I've had no problems when I used them, it's just like a normal sprayer for a rattle can, what do you need it to be good on rubber for?

 

uhhh...the mats are rubber.

 

I'd try Simple Green, make sure to get the concentrated one, don't get the already water down one. Couple that up with a firm bristle tooth brush.

 

ohh crap i was thinking these were the jr mats for some reason... I agree... simple green, scrub and you should be good.. let them soak for a while tho

 

I had superclean sit for a good hour, continuously keeping it wet & it didn't work. I'll try simple green tomorrow.

My co-worker said try some hydrogen peroxide?

 

I had some rubber mats a few years ago I purchased for my S10 Blazer. When cleaning them one day I noticed some of the white faded to a yellowish/brown color. It turns out the white on the mats was actually painted on. To restore the white color I went to the hardware store and bought a small can of white concrete paint. Maybe your mats were constructed the same way?

Plasticolor molds the color into the rubber, so its not paint.
