This past weekend I bought my first container, with a reserve in it (woot woot!), but I am back off to University for a few weeks until I can go back home to my DZ. There are a few dirt marks on the container that I would like to clean up, without having to have someone take the reserve out for me. Any tips on cleaning these marks up? Specifically, they are on: -outside reserve flap (small dirt mark) -main canopy cover flaps. Any tips or tricks would be greatly appreciated! -B
