You can do a number of things to make sure that your Crumpler bag looks the best it can. To begin with, here are a few things that won’t work. Never put a bag through the washing machine. Our bags are not meant to go through a spin cycle and therefore should also never be placed in a tumble dryer. The internal stitching and material can be affected by prolonged exposure to detergents and the heat of a tumble dryer will cause wet areas of the bag to wrinkle. Also it is hard for the padding to dry inside the bag after it has been completely immersed in water for a long period. Foam is porous and can trap water deep within itself when immersed and compressed. Think of it like a sponge, when you squeeze it in water it will absorb more.
The biggest deteriorating factor to a Crumpler bag will be the gradual erosion of the water resistant coating applied to the outside of the Chicken Tex Supreme™. This is unavoidable, as prolonged rubbing on the surface will erode the coating. After a while you may notice that when rain falls on the bag, it no longer beads and falls off. To fix this, first clean the bag with a watery sponge and some shampoo. This will get rid of the grime and leave the fabric in the best condition. After cleaning, allow the bag to dry. Then apply an off-the-shelf water repellent spray, which is usually used for leather or outdoor jackets. Again allow your bag to dry fully before use and your coating will be as good as new.
