I did it.

I machine washed my Porsche silver guard cover tonight and it came out great.

Went to the laundromat around the corner from my house. Picked out the largest front loader they had. Made sure no one was looking. Popped in the cover. Dumped about an ounce or two of Zaino car wash in the machine (figured it wouldn't leave behind any residue that would hurt my wax job). After I dumped in the un-measured amount of Zaino, I remembered that fron loaders like to foam-out if you put too much suds in them. It didn't seem to have a problem with Zaino (whew!)

Once that was done I put it in one of their dryers on the lowest heat setting. Took less than 30 minutes to dry.

It's back on the car now and seems no worse for washing it.
