Canvas Awning Mildew Treatment

Awnings require care to prevent mildew development.

Canvas awnings are made from various fabrics that include cotton or woven acrylic. Canvas awnings should be occasionally cleaned to prevent mildew growth, especially when your awning gets wet.

Preparation

Washing mildew off will help keep your awning clean.

Brushing the canvas with a scrub brush will remove mildew that has dried. Excess debris can be washed off with a mixture of mild detergent and water.

Rubbing Alcohol

A mixture of 50/50 rubbing alcohol and water may also remove mildew, as indicated by Mrs. Clean USA. Submerging a towel into the solution and using it to wipe the affected area can clean away mildew. The awning should be rinsed with water after cleaning.

Dont's

Using bleach on your awning can ruin the fabric. Chemicals contained in bleach can cause a reaction such as staining on your fabric.

Mildew Prevention

Using a mixture of 50/50 white vinegar and water can help prevent mildew growth. The solution can be applied in a spray bottle after cleaning your awning.
