How to Address Common Problems With Hardie Plank Process

There are various contaminants that can invade your hardie plank surface. Use the right cleaning methods for each type of contaminant to avoid damages.

Dirt, Dust, and Debris

Start with a soft, non-metal brush to lightly sweep away any loose dirt, dust, and debris from the Hardie Plank surface. Then, in the direction of the grain, gently run a wet soft cloth across the material, top to bottom, to clean off any remnants. Finally, using low-pressure water, rinse the Hardie Plank surface from top to bottom. Do this once or twice a year for maintenance.

Oil and Grease

To remove oil and grease from Hardie Plank surfaces, use a mixture of mild dishwashing soap and water. Apply the mixture using a soft cloth to wipe off any oil or grease stains. Then, gently wash away the solution using low-pressure water. Repetition may be required to completely remove more stubborn stains.

Mold and Mildew

Check your Hardie Plank surface for browse, green, red, or black spots that indicate mold and mildew growth. Find a mold and mildew remover that’s compatible with fiber cement and use a soft cloth or sponge to apply it to the affected areas. Rinse off any residual cleanser using a garden hose. Make sure to exactly follow the instructions on how to use the product.

The Hardie Plank Pressure Washing Process

Hardie Plank can certainly improve the appearance of your home, but it’s a delicate material that requires a careful touch.


Before every cleaning process, an inspection is necessary to pinpoint any problem areas that may be damaged while pressure washing. Washh makes sure to perform a thorough inspection Before starting any work and will report back any issues we may find that will impact the washing process. And provide the owner a report, complete with a quote for repairs.

Pressure Level

 Hardie Plank is more fragile than other materials, so too high a pressure can quickly inflict damage on them. Use pressure levels that don’t go beyond 1,500 PSI to clean Hardie Plank and keep it in good condition. Washh prefers to use soft washing techniques to ensure safe cleaning.

The Right Distance

Standing too close to Hardie Plank, even using a pressure level below 1,500 PSI, can still damage the material. Hence, make sure to stand at least 6 feet from the Hardie Plank surface during the pressure washing process.

Fan Tips

The wrong nozzle tip can cause serious damage on Hardie Plank surfaces, whereas the right nozzle tip can effectively clean them. It is recommended to use a fan tip to distribute the pressure, removing dirt and other filth without disturbing the material.


Combine pressurized water with industry-grade detergents made specifically for delicate materials to efficiently get rid of contaminants from Hardie Plank surfaces. Washh uses a proprietary solution tailor-made for the Hardie Plank material.
