In a simple procedure you can effectively re-proof the canvas anytime with Sea To Summit's Canvas Proofing product. This restores the canvas water repellency to new performance. None of this is true even for well made synthetic pack bags. Add to this the fact that making good repairs is always time consuming and thus expensive. Think two or three synthetic packs to the life of one canvas model. Then also think about the user. The significantly better wet weather performance of a canvas backpack will only enhance the chances of that backpacking experience being a positive one.

Canvas Care

Canvas fabric needs to be handled a little differently to most synthetic fabrics. The main reason for this is its 'proofing', a clear, waxy, resin mixture soaked into the fabric and heat set in the final production stage. This can be easily removed by detergents, soaps and common solvents. Hose off excess dirt and grime with clear, fresh water. Lightly brush off stubborn spots as you do this. Do not use soap, it's too difficult to rinse out. If you really do need to remove spots like margarine or vehicle grease then use laundry detergent dissolved in warm water and a soft brush. Alternatively, dab white spirit or dry-cleaning fluid through the affected canvas spot, soaking it up with an absorbent pad or towel on the other side. In either case some of the fabric dye colour will be lost. After rinsing and thorough drying your pack you can and should restore the canvas fabric proofing. Instructions for this are given below.

Re-Proofing Canvas

The waxy polymer proofing brew impregnated and cooked into the fabric at its final stage of production gives our pack canvas a high level of water repellency, as well as resistance to rot and mildew. While the extremely tight weave and cotton component of the yarn are largely responsible for the waterproof qualities of canvas it is a good idea to maintain canvas in top condition by applying a proofing agent as the need arises. We supply our DuraProof re-proofing compound ready packaged for use. Completely wetting out a sound, clean canvas pack bag with this formulation, followed by several days drying time, will restore original fabric performance. At the same time, it will treat the seams, zip tapes and thread so that wicking leakage is minimized, if not eliminated. Consider re-proofing your pack or pannier bags if any seepage becomes an issue. Detailed instructions are supplied with package.

Rarely, mildew may develop on poorly cared for canvas products. Bleach is deadly to mildew and on badly infected fabric may be the only solution that can save the day and the equipment. A more benign solution to low levels of mildew is a week under strong sunlight. Try this first.
