I keep my "ready to use milk crate" with all my 16 oz products in it( DS,WCW, APC. Ect.. Polishes, in&out , clay. And anything else I need to do the car). I keep that under my desk. I have all my gallon refills in my closet. Built a shelve above my clothes rack. And I keep all of my machine pads washing mitts brushes and buckets in the shed.
