How To Clean Your Canvas Shoes So They Look Good As New
Air dry the canvas shoes overnight.
Drying canvas shoes in a dryer can cause the canvas to shrink and can also produce yellowing of the canvas.
If your sneakers have removable insoles, it would be easier to clean and rinse them off outside of the shoes. An old toothbrush and a mild cleaning solution can be used for this. Simply clean the insoles with gentle scrubbing; rinse them off, and leave to air-dry.
