Aluminium roller shutters are built to handle the elements, but they still need regular cleaning to stay in top condition. Dust, dirt, salt spray (particularly in Adelaide’s coastal & inner city suburbs), and general grime accumulate on both interior and exterior surfaces over time. Left unchecked, this buildup can affect how smoothly your shutters operate and dull their appearance. Understanding how to clean aluminium roller shutters correctly ensures you remove the grime without accidentally damaging the protective finish.

The good news is that cleaning your roller shutters is a straightforward job you can tackle yourself with the right approach. This guide covers safe cleaning methods for both inside and outside surfaces, explains which cleaning solutions work best on aluminium, and identifies the tools you should use, and the ones to avoid at all costs to prevent scratches and corrosion.

At Roller Shutter Repairs Adelaide, we’ve spent over 20 years servicing and repairing shutters across the Adelaide region. We’ve seen how proper cleaning and maintenance extends shutter lifespan and prevents unnecessary repairs. We’ve put together this practical guide so you can keep your shutters looking sharp and operating smoothly between professional services.

What you need and what to avoid

Before you start cleaning your aluminium roller shutters, gather the right supplies and know which products can cause damage. You’ll need mild cleaning solutions and soft cleaning tools that won’t scratch the powder-coated or anodised finish. Having everything ready before you begin makes the job faster and ensures you won’t reach for something harmful in the middle of the task.

Safe cleaning supplies

Your cleaning kit should include gentle products that effectively remove dirt without harming the aluminium surface. Mild dish soap mixed with warm water works brilliantly for most cleaning jobs on roller shutters. You can also use specialised aluminium cleaners designed for automotive or marine applications if you’re dealing with stubborn stains or salt buildup.

For tools, stick to these safe options:

• Soft microfibre cloths or sponges for wiping surfaces
• Soft-bristled brushes (like car wash brushes) for textured areas
• Bucket for your cleaning solution
• Garden hose with adjustable nozzle for rinsing
• Step ladder for reaching higher sections safely
• Rubber gloves to protect your hands

Products and tools to avoid

Certain cleaning products and tools will damage your shutters permanently. Never use abrasive cleaners, scouring pads, or steel wool on aluminium roller shutters, as these scratch the protective coating and expose the raw metal to corrosion. Avoid harsh chemicals like bleach, ammonia-based cleaners, or acidic solutions (vinegar, citrus cleaners), which can strip the finish and cause discolouration.

Using the wrong cleaning products voids most manufacturer warranties and can lead to costly repairs or premature replacement.

Wire brushes, pressure washers set to high pressure, and rough scrubbing pads all cause surface damage that accelerates wear. When learning how to clean aluminium roller shutters, remember that gentle methods deliver the best long-term results without compromising your shutters’ protective layer.

Step 1. Prep and safety checks

Before you apply any cleaning solution, complete these essential preparation steps to ensure both your safety and the best cleaning results. Start by testing your shutters to identify any mechanical issues that might require repair before cleaning. Run them up and down slowly, listening for unusual noises or resistance that could indicate a problem with the motor, tracks, or guides.

Test the shutters before you start

Operate your roller shutters through their full range of motion at least twice. If they stick, make grinding sounds, or fail to open or close completely, you’re dealing with a mechanical issue that needs addressing before you tackle cleaning. Cleaning won’t fix operational problems, and forcing shutters that aren’t working properly can cause further damage.

Stop and call a professional if your shutters show signs of mechanical failure during testing, as cleaning could worsen existing problems.

Secure your work area

Position your step ladder on level ground and ensure it’s stable before climbing. Clear any furniture, plants, or obstacles from around the shutters to give yourself unrestricted access to all sections. If you’re cleaning exterior shutters, check the weather forecast and choose a day with mild temperatures and no rain expected for several hours. Lower your shutters completely so you can reach every section without overstretching from the ladder.

Step 2. Clean the outside of the shutters

The exterior surfaces of your roller shutters take the brunt of weather exposure, accumulating dirt, pollen, and salt residue from Adelaide’s coastal breezes. You’ll start your cleaning process from the top and work downward, which prevents dirty water from dripping onto sections you’ve already cleaned. Mix your mild dish soap with warm water in a bucket (roughly one tablespoon of soap per litre of water) to create a gentle cleaning solution.

Apply the cleaning solution

Dip your soft microfibre cloth or sponge into the soapy water and wring it out so it’s damp rather than dripping. Wipe the shutter slats horizontally, following the direction of the panels, and apply gentle pressure to remove surface dirt. For stubborn spots like bird droppings or tree sap, let the soapy solution sit for two to three minutes to soften the grime before wiping again.

Never scrub vigorously or use circular motions on powder-coated aluminium, as this can dull the finish and create visible wear patterns.

Rinse and dry thoroughly

Once you’ve cleaned all exterior surfaces, rinse the shutters completely using a garden hose with a gentle spray setting. Start at the top and work down to wash away all soap residue, which can leave streaks if left to dry. After rinsing, use a clean, dry microfibre cloth to wipe down the slats, preventing water spots and speeding up drying time.

Step 3. Clean the inside without removing them

The interior surfaces of your roller shutters collect dust, cobwebs, and indoor grime from everyday household activities. You don’t need to dismantle your shutters to clean them effectively from inside. Raise your shutters completely to access the interior slats, which allows you to wipe down each section while the shutter remains safely in its tracks.

Access the interior surfaces

Work from your step ladder positioned inside your home and use the same mild soap solution you prepared for the exterior. Dampen your microfibre cloth and wipe each slat horizontally, moving from top to bottom. The interior faces typically need less aggressive cleaning than outside surfaces, as they’re protected from harsh weather conditions.

Pay special attention to the bottom sections of interior shutters, which accumulate more dust from floor-level air circulation.

Remove stubborn interior buildup

For areas with sticky residue or heavy dust accumulation, apply your cleaning solution and let it sit for 60 seconds before wiping. Use a soft-bristled brush to gently dislodge cobwebs or dust from crevices where the slats connect. When learning how to clean aluminium roller shutters properly, you’ll find that interior cleaning requires less elbow grease than exterior work. Finish by rinsing with a damp cloth (water only) to remove soap residue, then dry completely with a clean towel.

Step 4. Clean tracks, guides and the pelmet area

The tracks, guides, and pelmet housing often collect the most debris on roller shutter systems, yet they’re frequently overlooked during cleaning. These components directly affect how smoothly your shutters operate, so keeping them free from dirt, leaves, and buildup is essential when you learn how to clean aluminium roller shutters comprehensively. Neglecting these areas leads to increased friction, premature wear on moving parts, and potential motor strain.

Clean the tracks and side guides – this is important to keep your shutter moving smoothly.

Start with the vertical side guides that hold your shutters in place as they roll up and down. Use a dry brush or vacuum attachment to remove loose debris, dead insects, and cobwebs from these channels. Once you’ve cleared the loose material, dampen a clean cloth with your mild soap solution and wipe the interior surfaces of each guide rail, removing any sticky residue or grime buildup.

For the bottom track where your shutters sit when fully closed, use a soft brush to sweep out dirt and leaves that accumulate in the groove. Wipe the track with your soapy cloth, paying attention to corners where debris typically gets trapped. Rinse with a damp cloth and dry completely to prevent water pooling.

Tackle the pelmet and housing area

The pelmet box that houses your rolled-up shutter collects dust and spider webs over time. Wipe down both the exterior casing and accessible interior surfaces using your microfibre cloth and cleaning solution. You don’t need to dismantle the housing to reach most areas effectively.

Regular cleaning of tracks and guides prevents 80% of common operational issues that homeowners experience with roller shutters.

Check inside the pelmet for any visible buildup around the roller mechanism and barrel, wiping away dust carefully without touching electrical components or motor parts.

Now that you know how to clean aluminium roller shutters safely and thoroughly, set yourself a regular cleaning schedule to maintain their condition and appearance. Most Adelaide homes benefit from cleaning roller shutters quarterly, though properties near the coast or in dusty areas may need monthly attention to combat salt spray and environmental buildup that accumulates faster in these locations.

Regular cleaning prevents dirt from hardening in tracks and mechanisms, which reduces wear on moving parts and extends your shutters’ operational lifespan. You’ll notice smoother operation and fewer maintenance issues when you stay on top of this simple task. Clean shutters also maintain their visual appeal and protect your home’s kerb value.
