I prefer the plastic totes with snap lids to keep dust and dirt out. And I have sent hamper with 3 sections for the dirty towels. They get divided glass and drying, polish removal and general purpose. Each gets washed separately. I find not getting anything on the glass and drying towels helps Them perform better over a long period of time. Something I learned from David Saunders. And the polish towels get a MF pre wash then hot rinse then a MF wash cycle and the GP a quicker cycle and hydrogen peroxide pre wash and a MF main wash.
