How to Clean James Hardie Siding?

Cleaning the Dirt

Windy days and big storms are the reason behind the dirt collected on your James Hardie siding. To clean it, you need:

  • Soft cloth
  • Soft brush
  • Garden hose
  • Water

First, brush the dust and dirt collected on the siding, and then wash your siding with the help of a garden hose. Then, use a damp cloth to wipe the smaller areas covering one side to the other in the direction where the planks, shingles, and panel siding are. In the end, wash your siding with the hose.

Pro-tip:  Work on smaller sections, each at a time. Always start from the top and then continue to come to the bottom. It will save the clean area from dripping or streaking.

Cleaning Mold and Mildew

At times, mildew looks like dirt, so when you wash your siding, check the planks, shingles, and panels. If you notice any mold or mildew, here’s what you are going to need to clean the James Hardie Siding:

  • A soft cloth or a sponge
  • Garden hose
  • Mildew cleaner
  • Water

Mix the cleaner with water, and spray the solution where you can see the mold and mildew. Then scrub that area, but do it with light hands. After that, rinse the area with a garden hose.

Pro tip: Do a patch test first for the cleaner, and wait for at least 24 hours. If it looks good, continue with the process.
