Elastomeric hat blocking form

A system for cleaning and blocking hats involves the use of a water impervious, elastomeric, foam form that permits a hat to be washed with a conventional laundry washing detergent without shrinking or losing its shape. The spongy, foam form is resiliently compressed somewhat so that, following laundering, the hat can be mounted upon the form in tight-fitting engagement therewith. The hat, mounted upon the form, is then left to dry in open air. The hat, once dried following laundering, may be removed from the form and sprayed with an appropriate aerosol spray that stiffens and retards deformation of the hat. The hat, while still moist from the spray, is placed back on the form and is then left to again dry in ambient air. Once dry, the hat is removed from the form. Following this treatment the hat is clean, but is not deformed by shrinking or otherwise. To the contrary, it retains its original shape and blocking.
