If your pocket square has difficult to clean stains, it is recommended to use a gentle washing method, such as using neutral detergent and warm water for cleaning. When cleaning, avoid excessive rubbing or using powerful washing equipment such as washing machines to avoid damage to the fabric fibers. In addition, to prevent the pocket square from becoming hard or deformed, it is recommended to replace it regularly and use a softener for maintenance.
In summary, when cleaning pocket squares, a gentle washing method should be used to avoid the use of strong oxidants such as bleach, in order to protect the fabric fibers and human health.
