We recommend spot cleaning the bags with a cold damp cloth and mild detergent, allow to dry completely. Waxed Canvas will naturally protect the fabric and repel moisture and dirt. Store in cool, dry environment away from direct sunlight. You can rewax your bag every 6-12 months which will restore the waxed canvas to top condition and prolong it's life.
Remove the stainless steel hardware and recycle, reuse or donate. Separate cotton layers, cut or shred into small squares (smaller pieces will decompose faster), and place into your at home compost bin.
Depending on the health and maturity of your compost bin, your bag will return to the earth between one week and three months.
