For those who don't want to remove the covers to wash there is another option to clean the normal day to day dirt that they collect. I bought a can of Resolve High Traffic Foam and coated all of the fabric on my front seats. Let it sit for a few minutes and then brushed all the cloth with a bristled brush. Resprayed the stained areas and then let air dry. Makes the truck smell all fresh and made my seats look like new again without the disassembly.

Just FYI.
