Understanding Mildew

Mildew is a type of fungus that thrives in damp, warm environments. It can manifest as white, gray, or black mold-like growths on fabrics, including outdoor cushions. Mildew spores can spread easily through the air and can cause respiratory issues in some individuals.

Materials Needed

To effectively treat mildew on outdoor cushions, you will need the following materials:

Soft-bristled brush
Vacuum cleaner
Bleach solution (1 part bleach to 10 parts water)
Vinegar solution (1 part vinegar to 1 part water)
Baking soda
Hydrogen peroxide
Trisodium phosphate (TSP)

Step-by-Step Treatment Process

Follow these steps to effectively treat mildew on outdoor cushions:

Step 1: Remove Loose Mildew

Using a soft-bristled brush, gently remove loose mildew spores from the cushion. Avoid scrubbing, as this can damage the fabric.

Step 2: Vacuum Thoroughly

Vacuum the cushion thoroughly to remove any remaining mildew spores.

Step 3: Prepare a Cleaning Solution

Depending on the severity of the mildew, use one of the following cleaning solutions:

Mild Mildew: Vinegar solution or baking soda paste
Moderate Mildew: Bleach solution or hydrogen peroxide
Severe Mildew: TSP solution (follow manufacturer's instructions)

Step 4: Apply the Cleaning Solution

Apply the cleaning solution to the affected areas. Allow it to sit for the recommended time per the instructions.

Step 5: Scrub Gently

Use a soft-bristled brush to gently scrub the cleaning solution into the fabric. Avoid scrubbing too hard, as this can damage the cushion.

Step 6: Rinse Thoroughly

Rinse the cushion thoroughly with clean water to remove the cleaning solution.

Step 7: Dry Completely

Allow the cushion to dry completely in a well-ventilated area or in direct sunlight. Do not use heat to dry the cushion, as this can set the mildew stain.
