General Outdoor Patio Umbrella Care Tips
It’s important to clean your outdoor umbrella regularly. Patio and backyard umbrellas get exposed to rain, sun, dirt, debris and pollutants including bird droppings and tree sap.
When not in use, such as during the off-season, you’re better off storing your patio umbrella under cover and protecting it from the elements. If you are storing your umbrella after use, make sure it has completely dried to avoid mold and mildew growth.
To keep your outdoor patio umbrellas looking great and extending their lifespan, regularly brush off dirt, debris and cobwebs. This should be done at least monthly or more if your umbrella is placed is completely exposed and/or under trees.
To avoid staining, don’t allow mildew, sunscreen or oily tree leaves to stay on the umbrella for long periods of time. Rather, follow the above care instructions.
The best way to keep an umbrella clean is by closing them when they are not in use and using an outdoor umbrella cover.
