Metal siding offers excellent durability and is a popular choice for homes because it’s low maintenance. But, like anything exposed to the elements, it requires cleaning now and then. This isn’t always as simple as it sounds. Figuring out how to clean metal siding effectively, without damaging it, is something I struggled with on my first house. I’ll walk you through the process, from simple washes to tackling tough stains. Contact our siding experts in West Chester, PA, for more help.
Why Regular Cleaning Matters
Regular cleaning helps maintain the protective coating, ensuring your siding lasts for years and keeps its shine. Keeping the siding clean can also increase energy efficiency. A build-up of dirt can absorb more heat, making your home warmer in the summer and potentially increasing those energy bills. Cleaning your gutters can help keep the surrounding siding cleaner. Hire a professional like RAM Exterior to get that grime off your siding.

Simple Cleaning for Everyday Grime
For regular cleaning to remove dirt, dust, and pollen, a simple wash with clean water is all you need. Aim to do this twice a year, in spring and fall.
- Pre-Rinse: Hose down the siding from top to bottom with a garden hose to remove large debris.
- Wash: Mix mild detergent (dish soap or laundry) with six gallons of water. About 1/3 cup of detergent works great. A nylon scrub brush (soft.) on an extension pole helps reach higher spots.
- Spot-Treat Stains (if present): Tackle these during your wash. Use a soft-bristled brush and a slightly stronger cleaner for spots. Be sure to spot clean the toughest spots where dirt might collect.
- Rinse: After scrubbing, rinse the suds from top to bottom with your hose. Don’t let soapy water dry.
- Final Check: Look for missed spots once everything dries. Clean them with the same wash-and-rinse approach. A pressure washer on its lowest setting can speed up cleaning for big areas.
Pressure Washing – Effective, But Risky
Pressure washing may seem easier for larger areas and is often touted as faster and more efficient. However, high pressure can dent your siding. High-pressure streams can force water behind the siding panels, leading to water damage. A soft material may be a good starting point if you haven’t cleaned your home’s siding before. If you use a pressure washer, use a low setting.
Start slow and test on a small, less visible area first. Hold the nozzle about 3-4 feet away from the siding. Pressure washing makes quick work of blasting dirt off large surface areas. You could use a sturdy ladder for high sections. However, high pressure can damage steel or vinyl sidings, needing costly repairs. Soft wash using low pressure is best.
Be wary of windows and openings to ensure seals aren’t broken. Consider a commercial or industrial cleaning detergent for stubborn grime and rinse after to avoid corrosion. It’s a great option when dealing with metal cleaning.
Tackle Difficult Stains
Then there are those times when a mere wash will not cut it. Materials like grease, oil, tape, adhesive, crayons, paint, or plastic marks are tough to remove. A hose bucket is nice for easy rinsing, but on harsh chemical cleaners, the finish of the siding must be carefully watched.
Here are some common stains and how to tackle them:
- Mildew/Mold: Mix equal parts white vinegar and water and scrub. For severe mildew, diluted bleach is stronger, but avoid overspray on plants. Always wear rubber gloves when handling cleaning chemicals, and check the manufacturer’s instructions first.
- Rust: Rust removal products work, and so does WD-40. If you’re seeing a lot of rust, address the cause.
- Grease/Oil: Use a degreaser with the spray aimed at the specific area.
- Chalky Residue: A product for restoring siding shine or even car or window wax can remove the residue.
When using strong cleaners, watch the windows, trim, and other exterior parts. Leaving cleaners on too long may cause corrosion or damage. Always follow the product instructions and take necessary safety precautions.
