Dry Baking Soda Method
Sprinkle dry baking soda onto the canvas exterior of the luggage. Scrub it with a brush to remove the soil. Brush away the soda residue with another brush. Dry baking soda almost always removes oil spots and most other types of soil. It also does a good job of cleaning the piece overall. This method is the easiest for your luggage.

Baking Soda and Water Method
If the dry baking soda didn't remove all the soil, try mixing about 4 tbsp. of baking soda in a cup of water. Dampen a clean cloth with the solution and rub it on the spot, being careful not to get the canvas too wet. Avoid getting the metal framework of the luggage under the canvas wet because doing so might make it rust. Dry the clean luggage with a hand held hair dryer.
Laundry Detergent Method
For more stubborn stains, rub the spots with a little laundry detergent mixed with water. Pre-treat it, if necessary, with Fels Naptha soap, again being careful not to get the fabric too wet. When the fabric is cleaned, dry the luggage with a hand held hair dryer.
