How To Clean Hardie Boards

Clean Hardie Board

Hardie boards are a popular brand of fiber cement siding. Basically made up of wood pulp and cement, they're durable, versatile, and come in a wide range of styles. They also last longer and are resistant to termites and mold. Cleaning them twice a year will ensure that your siding looks great. Keep reading to learn how to clean different types of stains off Hardie boards and other fiber cement siding.

1. Dust, dirt, and chalk: You'll need either a soft cloth or a soft brush. Don't use a scrub brush or other hard brush, or you can scratch the paint. Brush the dirt and then rinse the area with a garden hose. Repeat if necessary. If you're using a cloth, wet it with plain water and wipe the dirt away.

2. Oil or grease: Use a soft cloth and a mix of mild liquid dishwashing soap and water. Never use harsh cleaners on fiber cement siding. Wipe the dirty area to clean it, frequently rinsing with a garden hose.

3. Mold and mildew: For best results, use a cleaner made especially for the task, such as Mildew Check. Follow the instructions. When cleaning, use a sponge to scrub the dirty area and a soft cloth to wipe it. Afterward, use a garden hose to rinse it away.

One thing all of these methods have in common? They require a lot of time and elbow grease. Another option is pressure washing, but you have to be extremely careful not to use too much pressure or the wrong technique. Otherwise, you risk damaging the surface. Use a wide-fan tip about six inches from the wall, with a pressure setting less than 1,500 pounds per square inch (PSI).
