Step 1: Prepare a bucket and pour warm water, a little white vinegar, and mild detergent into it.
Step 2: Remove the umbrella cloth from the stand and place it on a flat surface to remove the dust first.
Step 3: Then use a soft sponge or brush to immerse it in the prepared cleaning solution. Scrub the entire outdoor umbrella fabric.
Step 4: After wiping away all the stains, use a hose to rinse the fabric clean. Wait until it is completely dry before reinstalling it back on the stand.
