Energy Saving and Time SavingEasy to install and operate. This hat washer for washing machine helps you save precious time and energy because you don't have to wash your hats by hand. Our hat rack for washing really helps bring new life to your hats.Patented DesignOur baseball cap/hat washer is patented for its special design - a mesh bag with a hat rack inside, unlike most baseball cap cleaners that only have a rack. The clever design holds the zipper slider in place and keeps the lid washer closed in the washing machine, preventing the lid from falling off.Washer and Dishwasher CompatibleThis lid cleaner is suitable for washing machines, dryers, and dishwashers, whether it is a front-loading washing machine or a top-loading washing machine. This design is great for keeping the shape of the hat and protecting your washing machine and clothes from scratches or tangles.Sturdy ConstructionThe baseball cap rack is made of super strong plastic (PP) and is very durable. This mesh bag has a slightly curved brim, which is compatible with flat brim and curved brim hats. It helps to maintain the natural curve of the brim of the hat.Multi-functionBoth adult and children's baseball caps can be washed. Without the hat rack, it can also be used as a regular laundry bag for wool hats, underwear, panties, small clothes, etc. It is also perfect for storing hats in a closet or in a suitcase.It can be stretched and dust-resistant as a hat rack, hat stand, hat rack, hat stand or hat storage bag.
