HOW TO CLEAN CANVAS
Remember to always test the product on a small area first.
Cleaning canvas needs more water than cleaning other materials. Wipe off as much water as you can when you're done with the cleaning.
Water stains may appear if the shoes don't dry properly. If that's the case, brush the stains with clear water and absorb as much water as possible with a towel. Air dry the shoes. Repeat if necessary.
