Q My climbing backpack smells like ginkgo nuts! I received a climbing backpack (unused) from a friend that is about 10 years old. There is no damage to the exterior, but there is a strong ginkgo nut smell from the inside. I think it's probably from the rubber backing used for waterproofing the fabric. I tried drying it in the shade, but the smell didn't go away. If there is another way to remove the smell, please let me know. A As everyone says, the cause is the deterioration of the waterproof coating. I was about to give up on my 10-year-old Patagonia waist bag, which was in the same condition. However, the following method eliminated that strong smell. What you need is "baking soda". First, sprinkle baking soda evenly on the backpack, especially on the inside, and leave it for 3-4 hours. Then, fill a bathtub with water and put the backpack in! Sprinkle more baking soda on top and leave it for another 3-4 hours. After that, wash it well with water and dry it in the shade, and the smell will disappear like a lie. However, the surface (appearance) will be cleaned, but the coating on the back will lose its luster and become rough, so the waterproof effect will be completely lost. I feel that the fabric has lost some of its firmness due to the loss of the coating, but it's not something to worry about. It may be difficult to wash a 70-liter bag by hand, but please do your best. Baking soda is available at drugstores, and don't forget the rain cover.
