I agree with all your comments, Ive cleaned loads over the years, but theres always one whch catches you unawares. I'll never forget one I cleaned with lukewarm water, It shrunk big time ( 2" on a 8ft width ) It then buckled like the sea the next day, I had a twin vac and it wasn't over wet.I've even heard of BW's shrinking in a hot porch. ( not cleaned )I would favour a disclaimer just in case you come across a similar nasty.
