Brush any loose dirt off the canvas with a dry, soft-bristled brush, such as an old toothbrush.
As a cleaning solution, combine a mild detergent with water.
A mild body soap, dishwashing soap, or a small bit of laundry detergent are all suitable alternatives.
Mix some water and soap together until bubbles appear.
Scrub the dirty sections of the bag with your brush dipped in the soapy water mixture.
By passing the bag under a little stream of water from a faucet, you can rinse the cleaned area.
After cleaning the stain and spots, blot them dry using a paper towel or cloth to absorb any remaining moisture.
Allow the bag to air dry after that.
