Felt and nunofelt withstand abuse by nature. Thus, cleaning is not necessary unless the product gets dirty. Unpleasant odours can be eliminated by ventilation. In case we would like to wash it, it should be done by hand in lukewarm mild soapy water.
Soak the felt in the water, and let it stay there for a while. The least we move and rub it, the lower the chances that the fabric’s becoming thick. After 30 to 60 minutes, while still in the water gently press it with your palm. Avoid wringing and rubbing. Then, take it out of the water and gently squeeze the remaining water out of the fabric. Finally, lay it on a towel and let it dry.
If the felt item is a bag, hat or something else with a particular shape, pad it with, for instance, a towel in order to keep the form.
Clothes moths are the greatest enemies of wool products. The best practice is to wear our scarf, hat or bag. Of course, it doesn’t mean that we should also wear them during summer: we can store our felt item in a plastic bag and turn it occasionally for ventilation.
