II also posted this on the old forum because I'm sure many of you only check one or the other.



Tomorrow, we are purchasing a used H21 SC at a consignment lot. The tramp has turned reddish (like rust color) due to water collecting in the middle of the tramp. What is the best way to clean this and get it white again? Are there any chemicals to avoid for this material?



Any suggestions for preventing this in the future. We will be storing it outside in the summer and inside in the winter (MN). We are hoping to avoid buying an expersive cover if possible.



Thanks, Doug
