1, Use a soft bristled brush(such as An old toothbrush) to brush off any loose dirt particles and impurities on the canvas areas of the bag.
2, Mix your cleaning solution. Any mild detergent mixed with water will work as a cleaning solution. Gentle body soap, dishwashing soap, or a small amount of laundry detergent, are all viable options. For about a cup of water, consider using about ½ a teaspoon of mild detergent. Use your old toothbrush to mix up the water and soap until some bubbles start to form.(You could also use a small amount of bleach if your bags are white, but be aware that bleach can potentially yellow the canvas fabric. A mild detergent is the safer bet.)
3, Dip your old toothbrush into the soapy water mixture, and start scrubbing at the dirty areas of the bag. Move the toothbrush in circles to thoroughly loosen the dirt and remove the stains.
4, Rinse the bag. You can rinse the canvas of the bag by running it under a small stream of cool water from a faucet.
5, Dry the bag. Once it is cleaned, dab them dry with a paper towel to soak up any remaining water. Then allow it to dry naturally, outside in the sun.
