Anyone got any good ideas how to clean the(on mine) white yeti logo on the car mats?

I've tried a carpet cleaner but it hasn't made much difference, so I just thought someone may have tried and found some product that does a good job?

Is the white bit a rubber material?(sorry mine are so this might not be useful for you) Magic Erasers work well on white rubber,JML make them. 

I use Vanish carpet shampoo on my carpet mat logos

Cleans really well, then put them up against a radiator when the wife is out

Material logo..

Thanks chris that's the carpet cleaner I tried, maybe just not giving it enough elbow grease!

I will give it another go and maybe leave it on a little while longer this time.
