Our co. has pretty much given up on exterior ptg as here in the northeast there is so much downtime with weather and other factors that I can no longer find it profitable. I do have to repaint a ranch in the spring for a great old time customer. The problem is there is a lot of mildew on the siding and trim as well as 14 pairs of canvas awnings. I will power wash the house and trim but what about the canvas awnings which are also covered with black mildew. What would be a safe product to use on sewn canvas to remove mildew without bleaching the color or disolving the thread used to sew these beautiful awnings together yet still remove the mildew.
