Things You'll Need
Vacuum cleaner with attachment
1 cup rubbing alcohol
Storing wet or damp canvas shoes without adequately airing them out will cause them to become moldy. Mold spores are drawn to dank, poorly ventilated conditions, such as those in damp canvas shoes, and rapidly multiply. Canvas shoes infested with mold gradually begin to smell musty and become discolored. If neglected, the canvas shoes will deteriorate due to the mold spores and ultimately be ruined. Fortunately, rubbing alcohol kills and removes mold on canvas shoes. Promptly remove any mold from canvas shoes to protect them from damage.
Take the moldy canvas shoes outdoors. Brush any loose mold off of the shoes with a whisk broom.
Suck additional mold out of the inside and outside of the canvas shoes with a vacuum attachment. Glide the attachment over every accessible inch of canvas.
Add 1 cup of rubbing alcohol to a bowl with 1 cup of water. Mix the alcohol solution completely.
Wipe the canvas shoes with the alcohol solution applied to a white dishcloth. Lightly moisten the dishcloth with the solution and don't soak the shoes with the solution. Gently rub the moist dishcloth over all remaining mold spores until they disappear.
Let the damp shoes thoroughly air-dry in the sun.
Use electric fans and heaters to speed up the drying process.
Spot-test a small amount of rubbing alcohol solution on the canvas shoes before applying it.
