Well I went all in and just washed them in the machine on the "hand wash" cycle. I hung them out to dry, and...they came out great! They cleaned up well and I didn't have a hard time getting them back on the cushions. (No more than expected) Don't know how well they would hold up doing that on a regular basis, but being that our TT was used when we bought it, I had to wash the "other people funk" out of the covers. Thanks for all the great advise!
