Felt is a stiff type of fabric that is considered to be one of the oldest fabrics in the world. Felt requires special care and can be damaged quite easily, so knowing how to properly clean it is essential. Unlike many fabrics, felt isn't woven, but pressed. Cleaning felt is more time-consuming than it is difficult. With a little time and know-how, this highly temperamental fabric can be properly cleaned without damaging it.
Fill the sink with warm water. You can also use a shallow bowl or even the bathtub for this.
Add a tablespoon of mild detergent and agitate the water with your hand to help it dissolve.
Set the fabric in the water and gently move it around. Use your fingers to gently brush soiled areas to help clean it.
Compress the fabric between your fingers gently to push out any excess water by starting at one end and working your way down.
Lay the felt flat on a flat surface to air dry.
