Waxed canvas is an amazing material that is long-lasting and water-resistant, but does need a bit of care over time to maintain its repellence.
To clean, gently use a scrub brush with water, rinse, and let dry.
For spots or stains, use a bar of mild bar soap, saddle soap, or waxed canvas cleaner, but always test a small area first.
After significant wear (such as your jacket has dried out or lost water repellence), it is suggested that you re-wax your item with a product such as Otter Wax.
Do not machine wash, dry clean, or use detergent on your waxed canvas products.
To maximize the life of your product, hand wash or machine wash on delicate cycle with cold water and lie flat to air dry.
