Sooooo, yes it got washed but not on purpose. Some screwball forgot it outside on Easter Sunday propped up against the grill near where I have the Blackstone. It's rained 3 times since then and a non-stop drizzle for the last 2. I looked out the window today and went "DAMMIT"!!
Curled up like a thin overcooked pork chop! So I already tried the wet towel thing for 6 hours as Craig suggested with several re-soakings and I still could not put enough pressure on it to flatten it without it feeling like it wanted to snap, got it maybe 2/3 flat. So now it's taking a warm bath in the tub, completely submerged and will put it under the heavy end of the recumbent bike and give it a couple days to dry and see how straight I can get it. Figure I'll take my time with it because it's game over if I snap it........Doh!!
