Caring for your Brushes With proper care, Trekell brushes will maintain their quality and paint just like the day you opened them! Clean your brushes immediately after each painting session. Trekell Linseed Oil Soap is recommended for the clean-up of oil-based media. Trekell Coconut Oil Soap is recommended for the clean-up of water-based media. Wet bristle and work soap into brush thoroughly. Rinse until lather runs clear. To prolong the life of your brush and retain its shape, use our Trekell Brush Restorer. Tips Soak your brushes in a brush holder that keeps the brush heads above the bottom of the vessel. Don't use the same brushes for watercolors, designer colors, or gouache as you do for acrylic paint. Keep your brush handles dry to prevent them from cracking and loosening. Ensure that only the bristles are soaking, do not allow water into the metal piece that holds them. Protégé Bristles Ingeniously engineered synthetic paint brush alternative to Kolinsky sable hair.
