KITSCH’s Bun Forms are made from a synthetic fiber with a porous texture. They should be washed by hand. Let the form soak in sudsy water for about 3 to 5 minutes. Gently squeeze the suds through your bun form. Rinse thoroughly with cool or cold water. When you are finished washing, lay the bun form flat on a clean, dry towel and roll the towel, jellyroll style, and apply pressure to squeeze out excess water. Unroll; remove the form and lay flat on another clean, dry towel to finish air-drying.
