Shell chair removable cover -- cleaning tips?
I bought a Summit-made shell chair off craigslist that came with a detachable cover. Posted about this a couple of months ago. Now have the chair and am posting better pics of it. As you can see, it is dirty as all get-out.

Does anyone have any tips or experience with the best way to clean these, or otherwise have any advice or feedback?

I would try it
Even if LRF is right you have nothing to lose. I would be tempted to put it in a tub with woolite. No scrubbing with a brush though, you might fuzz it up. If you dont want to try I would be interested in the cover as is, it is in better shape than mine so please dont toss it.
