I have an 82 Vanagon that I have had for maybe 7 years now.  I've been a part of this e-mail list for some time but have yet to post anything.  Here goes.  I'm wondering if anyone has any ideas on if and how to clean the canvas tarp.  I live in the rainy NW and just discovered I have some stains from moisture/mold on my canvas.  I tried to use dishwashing soap to clean which helped some but am left with some dark discolorations.  Any thoughts?

Thank you!
