Hey guys, wondering if anyone has a solution to clean up fly spots on a canvas tent? Long story short I found a used one in "excellent condition", drove 3.5 hours, seemed good shape even though I saw a few of these spots. We met in a parking lot so I wasn't able to set it up and have a good look. It appears the previous owner has some flies or lady bugs seek shelter in the fold of the door and made a mess. It's really just on the door and I would like to clean it up. Its a 12x15 davis with rain fly and a 8' porch.
