To keep your Piñatex™ bag in top condition, it is recommended to wax it on a regular basis by using a natural wax (the manufacturer of the material recomends Barbour-Wax). Waxing the material is not only for protection, but it also gives the material a soft patina which you'll love.
Any soiling should be cleaned with water using a damp soft cloth or sponge.
Do not use heaters or similar hot items as the material might dry out.
