I keep my towels inside until I need to use them. Then grab a handful, throw in a empty clothes basket and tote it out to my detail. Then as they get dirty I just throw them in the clothes basket as I go haha. I know pretty simple. Products are stored inside since I live in the Midwest and it’s about to start getting below freezing (not climate controlled garage). Well I don’t think I helped you but mine are organized on a basic wire shelf from Home Depot.
