Wash Oilskin articles with warm - not hot - water. Best is a sponge, a soft brush or a cloth. Do not use harsh detergents or mechanical means like scouring sponges and brushes. After drying please spray with Fabsil 'Wax Cotton' (please see the manual). The garment is fully operable again and will remain intact for a long time. Please note: a certain patina is part of the appearance of this wear.
