Ranger’s Color Adirondack Color Wash is an acid-free non-toxic, water-based dye that was developed for use on paper, fibers, fabric and more.
The label directions state:
Spray directly into an absorbent surface. To blend tones apply additional colors while wet. Heat set inks with an iron or heat tool. For fabric: After heat setting, rinse in water to remove excess dye. Dry fabric with iron or clothes dryer. Allow fabric to set for 72 hours before washing in cool water with mild detergent, no bleach. Not for children under 12.
