Tips for Cleaning James Hardie Siding

James Hardie siding is known for its durability and low maintenance. However, regular cleaning is essential to keep it looking pristine. Champion Restoration and Construction offers expert tips to clean your James Hardie siding effectively without causing any damage.

How Often Should You Clean Hardie Board Siding?

Biannual Cleaning

Similar to gutter maintenance and window cleaning, Hardie board siding should be cleaned twice a year, preferably in the spring and fall. This regular cleaning removes dirt, grime, pollen, bird droppings, and other debris, helping to preserve the appearance of your home and maintain its curb appeal. Additionally, routine cleaning provides an opportunity to inspect the siding for any potential damage, such as cracks or mold growth, allowing for timely repairs and ensuring the siding’s longevity. Regular upkeep of Hardie board siding not only enhances your home’s aesthetic but also contributes to its overall durability and value.

Can You Pressure Wash Hardie Plank?

Avoiding Damage

Using a pressure washer is not recommended for cleaning Hardie plank siding, as it can cause damage to the material if not used with great care. The high pressure can strip away the protective finish and potentially cause cracks or other issues. Instead, opt for a low-pressure garden hose, which is gentle enough to clean the siding effectively without causing harm. Complement this with a mild detergent and a soft brush for removing stubborn stains or buildup. This method ensures that your Hardie plank siding remains in excellent condition, preserving its appearance and functionality while avoiding unnecessary damage.

Cleaning Supplies Needed

Basic Cleaning Supplies

You likely have most of the necessary cleaning supplies at home. Here’s what you’ll need:

  • Garden hose with a spray nozzle
  • Dish soap (e.g., Dawn)
  • Bucket
  • Soft cloth or sponge
  • Soft-bristled brush (avoid metal bristles)
  • Brush extension, if necessary

Cleaning Process

Ideal Weather Conditions

Choose a day with overcast skies to prevent soap from drying on the siding. Avoid cleaning on rainy or sunny days.

Step-by-Step Cleaning Guide

  1. Rinse the Area: Start from the top and rinse the siding using the garden hose and spray nozzle.
  2. Clean with Soap and Water: Mix dish soap with water in a bucket. Use the soft cloth or sponge to wipe away dirt and grime.
  3. Use a Soft-Bristled Brush: For stubborn dirt, use a soft-bristled brush. Rub along the grain of the siding, not against it.
  4. Final Rinse: Rinse the cleaned area from top to bottom to remove any remaining soap.

Removing Mold and Mildew

Mildew Resistance

James Hardie siding is impervious to mold, mildew, and rot due to its lack of organic materials. This eliminates the need for harsh mildew cleaners. Simply follow the standard cleaning steps to maintain its appearance.

Conclusion
