I use a roller cart I purchased at Costco. It is one of the chrome mesh types. I originally used it for wash and polish materials. the lowest shelf is used to toss the wet mitts, rags, etc, and they drain nicely.
I have the basket installed in the top position
Over time it has been used as a tool cart with nothing more than a cardboard box bottom in the basket . I need to upgrade to trays like MartinSR has
