5 Simple Ways to Clean Any Shed Siding


Regardless of whether the siding on your shed is steel, wood, or vinyl, it’s important to keep it clean. By cleaning your siding on a regular basis, you can prevent the growth of mildew and clean away stains before they become a permanent part of your shed. With a few simple tools, you can keep your siding in great shape!

Use a Mixture of Dish Soap and Water

First, use your garden hose to rinse the siding. This loosens the dirt ahead of the scrubbing process. Next, get a bucket and fill it with water. Keep in mind that you need just a few tablespoons of mild dish soap for every five gallons of water. Use a long-handled scrub brush to apply the soapy mixture to your shed’s siding. It’s best to use a brush with soft bristles so you don’t leave any scratches behind. After you work your way around the entire shed, use the hose to give the siding a final rinse. This cleaning method is appropriate for wood, steel, and vinyl siding. I suggest you wash your shed in the morning on a sunny, warm day so it has plenty of time to dry before night falls.

Use a Power Washer

A power washer is more effective at loosening and removing dirt from a shed’s exterior than the average garden hose. You can rent or even buy a power washer depending on how often you plan to use it. Many power washers come with attachments such as a cleaning wand and various types of soft-bristle rotating brushes to help you thoroughly clean your siding. There are cleaning solutions available to mix with water so the power washer is getting rid of stains as it’s knocking dirt off of the siding. A power washer can be used on wood, steel, and vinyl siding. Make sure to use a low pressure setting when power-washing your wood or vinyl siding: This prevents the spray from damaging the surface of the siding.

Remove Mildew With a Special Cleaner

If you have spots of mildew on your shed’s siding, you can use mild dish soap and water to remove it. You’ll have to use some elbow grease to scrub the area. I suggest using an old toothbrush to scrub those small, stubborn areas of mildew. After rinsing with water, give the area a few hours to dry before examining your work. There are sprays available in home improvement stores specially made to remove mildew from vinyl, wood, or steel. If you use a commercial mildew remover, wear rubber gloves and protective eyewear so you don’t get any of the solution on your skin or in your eyes.

Try a Water and Vinegar Cleaning Solution

A mixture of water and vinegar is an effective cleaning solution for vinyl siding. Your mixture should consist of 70 percent water and 30 percent white vinegar. Mix it in a bucket and use a traditional mop or a sponge mop to clean the siding from the top down. Leave the mixture on the siding for about 30 minutes, then rinse it off.

Use a Laundry Detergent and Water Mixture

This mixture consists of 1/3 cup of laundry detergent for every six gallons of water. Put this solution in your power washer and use it to clean your steel siding. This will help remove mildew, dirt, and other unwanted buildup on your steel shed. Be sure to rinse the siding with plain water.

Taking care of the siding on your shed keeps it looking good and free of mold and mildew. Thanks for reading! – Alan
