Fiber cement siding is one of the most durable and low-maintenance siding materials on the market today. While fiber cement siding requires minimal upkeep, regular cleaning is still essential to keep the material (and your home) looking spick and span. Since it is a special material, fiber cement requires certain cleaning methods to avoid premature damage.
In this article, James Hardie® siding installer DryTech Roofing Company, Inc. shares tips on how homeowners can clean their fiber cement siding safely and properly.

How to Clean: Dirt

Nobody likes to see their siding gather dust and dirt. Luckily, dirt on your siding is pretty easy to remove. That is, if you don’t let the dirt sit there for long periods. But whether it’s a thin coat or a thick layer of dirt, these cleaning tools and methods prove fool-proof. You’ll need:

  • Soft cloth or brush
  • Water hose

Start from top to bottom. Brush off the dust from the siding surface before rinsing with water. If you’re using a soft cloth, wet the cloth and wipe the siding plank from side to side. Rinse with clean water. No need for cleaning solutions.

How to Clean: Oil, Grease, and Natural or Organic Contaminants

When dealing with a James Hardie fiber cement siding that’s slick with oil or grease, you’ll need the same tools. In this case, however, you can use a mixture of water-diluted mild liquid dishwashing soap in a bucket. Wipe the siding with the soapy cloth and immediately rinse off.

How to Clean: Mold and Mildew

Use a soft sponge and a manufacturer-approved mold and mildew cleaning solution to get rid of the infestation. Be careful when using these chemicals and follow instructions to the letter.

Whatever type of siding grime you’re dealing with, make sure to avoid using pressure washers or any abrasive material.
