How to Get Rid of Mold on a Fabric Umbrella

Kathryn Hatter

It can be distasteful to open your patio umbrella and discover mildew forming within the folds of the fabric. Mildew forms in damp places where oxygen does not circulate effectively. When you keep a fabric patio umbrella folded tightly after being wet, you create an ideal environment for mold and mildew to develop. Take immediate steps to get rid of this mold to remove the unsightly stains and to make sure that family members are not exposed to the mold spores.

  1. Open the fabric umbrella to assess the extent of the mold. Make sure you are outside in fresh air to remove the mold from the umbrella fabric.

  2. Put on the rubber gloves and use the stiff brush to brush briskly at the mold on the fabric. Often just brushing at mold and mildew spores will remove a significant portion of the staining spores.

  3. Mix 1 tbsp. of the oxygen bleach with 2 cups of hot water in the bucket. Test an inconspicuous area of the umbrella fabric with a small amount of the bleach mixture to make sure it does not damage the fabric. After waiting for several minutes, if no change results in the fabric, apply the bleach mixture to the mold stains with the sponge. Leave the bleach mixture on the stains for 30 minutes and then rinse off with clear water.

  4. Mix 2 tbsp. white vinegar with 1 cup of warm water. Apply the vinegar solution to the mold stains with the sponge and rinse off with clear water.

  5. Open the umbrella wide on a sunny day and allow the sun to shine directly down onto the mold stains. Often sunshine is all that is necessary to remove mold and mildew stains from fabric naturally.
