How to Clean your James Hardie Siding during the Spring

How to Clean your James Hardie Siding during the Spring

There’s just something special about the look and feel of things when they’re sparkling clean — whether it’s the kitchen tiles, your car, or the siding and trim of your home. It not only looks fantastic, it also makes you feel like you’ve achieved something! To keep your home’s siding looking just as impressive, it’s a good idea to give it a wash once or twice a year. Just grab your garden hose and give the siding a good rinse every six to twelve months. Avoid using a high-pressure power washer though; a low-pressure hose and a soft, medium bristle (non-metal) brush are all you need to effectively remove dirt and debris from James Hardie siding and trim. Whether you’re tackling dirt, grease, or mildew, we’ve put together the perfect set of tools, solutions, and methods to keep your siding as clean as a whistle!  

Top 3 reasons your siding might get dirty

and how you can clean it up to make your home look absolutely stunning!

How to Wash off the Dirt?

Tools:
Big storms and breezy days can sweep up dust and dirt that stick to your home’s siding. To tackle this without any tough scrubbing, all you need is a soft cloth, a gentle brush, and a garden hose. Make sure to steer clear of any hard metal brushes or abrasive sponges, as these could scratch your siding’s lovely finish.

What product should I use?:
Just water!

Method:
If you’re using a brush, gently sweep off the surface dust or dirt from the siding, then give it a good rinse with your garden hose. If you’re using a soft cloth, dampen it and wipe the siding in a horizontal motion, following the direction of the planks, shingles, or panels, until it’s clean. After that, just rinse off the area with clean water.

Pro Tip:
Always clean from the top down. Tackle a small section at a time to avoid drips or streaks on the areas you’ve already cleaned.

 
 
 

OIL, GREASE OR OTHER ORGANIC CONTAMINANTS

Tools:
Oil-covered hands and greasy fingers can make their way to your home’s siding, in which case you’ll want to grab a soft cloth and a garden hose.

What product should I use?:

Mild liquid dishwashing soap and water.

Method:
Grab your soft cloth and saturate it with soapy water. Clean the stained siding while rinsing your cloth frequently. Once the siding is completely sudsed up, use a garden hose to rinse the area.

Pro tip:
Keep Wet: Do not allow soap or cleaners to dry on the siding. Instead, continually rinse the area until all of the soap has washed off of the siding.

MOLD AND MILDEW

Tools:
Sometimes mildew might just look like a bit of dirt, so take a close look at your siding’s planks, panels, or shingles when it’s cleaning time. If you find any mold or mildew, you’ll want to have a soft cloth (or soft sponge) and a garden hose handy.

What product should I use?:

A cleaner designed specifically for mildew, mixed with water.

Method:
Gently scrub the affected areas with the mildew cleaner, paying close attention to the product’s instructions. After scrubbing, give the area a thorough rinse with your garden hose.

Pro Tip:
Be mindful when using chemicals: If you decide to use a stronger chemical cleaner on your siding, make sure to read the label carefully and handle with care to avoid damaging the siding’s finish.
