If you have vinyl siding, you're probably all too familiar with the relentless battle against mold and dirt. Over time, these pesky buildups can take a toll on the look and longevity of your siding. But don't worry keeping your vinyl siding looking fresh and clean isn't as daunting as it may seem. In this guide, you'll discover simple yet effective cleaning methods, plus tips on preventing mold and dirt from making a permanent home on your exterior.Causes of Mold Growth
Mold grows in places with a lack of sunlight and excessive moisture. Your siding could be exposed to excessive moisture for several reasons including clogged or faulty gutters, leaky spigots, or the ground being constantly wet can contribute to mold. Excessive shade around your home trees or bushes can prevent your siding from drying.
Cleaning Methods
There are a few ways you can clean your vinyl siding. Each method has advantages and disadvantages.
Power Wash
It may be tempting to power wash the side of your house to avoid hand scrubbing, but you risk damaging the siding. CertainTeed, the popular exterior and interior building product brand, does not recommend power-washing vinyl or polymer siding because it can cause moisture intrusion, damage, and discoloration. It can be done if you are experienced and use the right equipment. If you want to power wash your siding, the safest route is to hire a professional or be extremely cautious.
Spray Method
A safer alternative to power washing is the garden hose spray bottle method. Attach a garden hose to a spray cleaner to clean the siding. The cleaner with the pressure of the garden hose will clean most of the dirt or mold off the siding.
One disadvantage of the spray bottle method is the bottles are sold in smaller sizes. If you purchase a cleaner in a gallon or more you can use a hand sprayer with a pump. A handheld sprayer means that you are not confined to the length of the hose.
You will need to rinse the cleaner. You may also need to scrub some of it by hand or use a second application. Be sure to read the instructions carefully.
Cleaning by Hand
Some people prefer the old-fashioned method of cleaning siding. Fill a bucket with water and cleaning solution or a germicidal bleach concentrate and scrub with a microfiber cloth or a long-handled, soft-bristled brush. If you would like a more natural cleaner, use vinegar and water. You may have to scrub more to remove stains. Rinse the dirt and clean it with a hose.
Ways to Prevent Mold Growth on Siding
The mold on your siding should be cleaned regularly, but there are ways to prevent it.
- Plant trees and bushes away from your home to give your siding more sun exposure.
- Move sprinklers away from your home.
- Fix leaking faucets and hoses to reduce moisture in the yard.
- Clean gutters and downspouts at least twice a year.
- Ensure that your dryer vents into an area that is not enclosed.
- Inspect your siding a few times a year so you can clean any spots before it goes too far.
Conclusion
Be cautious with power washing because it can potentially damage the siding. Attaching a spray bottle to a hose is a great way to clean the siding with minimal hand scrubbing. For anyone who prefers the old-fashioned method, use water and cleaner with a long scrub brush. Know the causes of mold buildup and how to prevent them. Remember to clean your vinyl siding at least once a year.
