Clean in the kitchen sink
 

Use a kitchen brush

Wash, get in there with the brush and let to drip dry!

Great Mats
 

Should be standard equipment! Got my i2 yesterday and i cannot imagine riding my I2 without it. Great fit and makes it nice to ride and when i got hom took my air compressor and blew the mat out and they are now clean.

My feet always hurt, so anything that reduces the wear and tear on them is welcome. The comfort mats help extend the length of time I can glide. They seem to give a more confident grip of foot to platform when hitting bumps.

I think they're great!
 

I highly recommend the comfort mats. I agree with others that they do seem to accumulate dirt and grime and are not the easiest things to clean but the added comfort they add to the gliding experience makes it totally worth it.
