Machine wash and tumble-drying can damage for example the metal parts of the zipper or a stiff visor, especially if machine washing a suit with visor and attached boots. We recommend the suits to be hand washed at maximum +40°C using a detergent and a soft rag or a smooth brush. Let the suit air dry or use a fan. Alternatively, use specially designed washing equipment such as Top Trock®, used by many fire brigades, which is a good and gentle way of cleaning and drying the suit. NOTE: It is important to take away all moist in the suits to avoid bacteria and fungus growth. See the Trellchem® suit manual for further information about maintenance of Trellchem® suits.
