I have a brand new double 12'x12' net that sprinklers got the bottom half wet. The grips let it dry before they put it away but there is a white line that transitions between where the sprinklers got it and the area that remained dry. My main use for the net is to knock down exposure when looking out windows. Since I shoot through it I need it as clean as possible. Does anyone have any experience cleaning nets? I'm not sure I trust a dry cleaner with it. Please let me know if you have any suggestions. Thanks.
