1. Remove the paint from canvas with a clean brush or a cloth, soaked in water, if the paint is still wet. Oil-based paints are easier to remove than acrylic ones because they need more time to dry. Watercolors are always easy to remove as they dissolve well in water even when dry.
2. Use a putty knife to scrape away the dry layers of acrylic or oil paint. Be careful not to damage the canvas, though.
3. Use rubbing alcohol to remove dry oil-based paints. Dip the soft cloth in the alcohol and apply it gently to the paint that you'd like to remove.
4. Use gesso, which resembles paint but is used as a primer, to cover the layers of paint that you couldn't remove from the canvas.
