I found this article on a link on walltentshop.com and tried it out. Worked really well and took off all the light and relatively recent mildew and stain and knocked down the older mildew spots pretty well. Not sure I would want to use straight vinegar, but that is the next step if I get any more issues with midlew in my tents..
