What's the most effective way to clean "carpeted" wheel wells?

I am curious what is the easiest way to clean those carpeted wheel wells that are so common on today's newer cars.

Is there a brush or some sort of tool that can be purchased to scrub them? I see on alot of more expensive cars, the wheel wells are carpeted and all kinds of crap gets embedded in the material and is a bit of a pain to remove.

Are there any tricks that you guys like to use?

 

I just use a brush and then pressure wash works good.

 

I just blast them with a pressure washer and that usually gets everything off. But mine is never too dirty.

i typically spray it down with a degreaser that im using when cleaning my tires and then pressure wash them
