If you’ve got louvre windows in your Perth home, you’ll already know they’re fantastic for catching that afternoon sea breeze. But here’s the thing: the best way to clean louvre windows isn’t quite as straightforward as wiping down a standard pane.
Those horizontal slats that make louvres so brilliant for ventilation also have a knack for collecting dust, salt spray, and grime. And in Western Australia’s climate, that buildup happens faster than you might think.
At Perth Window & Door Replacement Company, we’ve been helping Perth families maintain and upgrade their windows for over 40 years.
We’ve seen firsthand how proper cleaning can extend the life of your louvre windows and keep them working smoothly for many years. So let’s walk through exactly how to clean louvre windows properly, without the headache.
Why Louvre Windows Need Extra Care in Perth
Perth’s climate is a bit of a double-edged sword. We get over 250 sunny days each year, which is brilliant. But all that sunshine comes with intense UV rays, and if you’re anywhere near the coast, there’s the coastal wind bringing salt spray inland up to 10 kilometres.
That salt doesn’t just sit on your glass louvres; sodium chloride, magnesium, and calcium residues actually bond chemically to the surface.
We would recommend cleaning windows every 3-6 months if you’re within 5 kilometres of the ocean. Leave it longer, and you risk salt-crystal etching that can permanently cloud your glass.
What You’ll Need for Routine Cleaning
Before you start cleaning louvres, gather the right tools. You don’t need anything fancy, but having everything on hand makes the job much less tedious.
Basic cleaning kit:
- Two buckets (one for cleaning solution, one for clean water)
- Microfibre cloth or soft cloth (lint-free is best)
- Soft sponge
- Old toothbrush for hinges and moving parts
- Vacuum cleaner with brush attachment
- Squeegee or paper towels for drying
Cleaning solution options:
- Warm water with a few drops of mild detergent works for most routine cleaning
- 50:50 white vinegar and water mix for stubborn grime or cloudy film
- Rubbing alcohol for sticky spots
Be sure to avoid harsh chemicals and abrasive cleaners. They might seem like they’d cut through dirt faster, but they can scratch glass and damage aluminium window frames. Stick with gentle options and you’ll get a streak free finish without the risk.
Step-by-Step: How to Clean Louvre Windows
The cleaning process is a bit more involved than washing a regular window.
1. Start with the vacuum
Use your vacuum cleaner with the brush attachment to remove loose dust and dirt buildup from the slats, frame, and window sill. This prevents you from just smearing dirt around when you start washing. Pay extra care to the hinges and moving parts where dust loves to hide.
2. Open the louvres fully
This gives you access to both sides of each slat. If your jalousie windows have a crank mechanism, make sure it’s working smoothly. If it’s stiff, that might be a sign you need professional help with maintenance or repairs.
3. Wash each slat individually
Dip your soft cloth or sponge into your cleaning solution, wring out excess moisture, and wipe each glass pane from one end to another. For aluminium frames, stick with plain warm water or very mild detergent. Don’t spray vinegar solution directly onto aluminium as it can cause oxidation over time.
Work your way down from the top slat to avoid dripping dirty water onto already-clean surfaces. This method prevents streaks and ensures you don’t miss any spots.
4. Tackle stubborn stains
For cloudy film or salt residue that won’t budge, use your vinegar-water solution and let it sit for 30-60 seconds before wiping. An old toothbrush works brilliantly for getting into crevices around the frame and hinges. Just be gentle to avoid scratching.
5. Rinse and dry
Use clean water to rinse any remaining soap or vinegar, then immediately dry each slat with a clean microfibre cloth or paper towels. This is important: leaving windows to air-dry in Perth’s heat (especially when it’s over 30°C) leads to streaks. You want to wipe them dry straight away for that streak free finish.
6. Clean the window sill and screen
Don’t forget the sill and any fly screens. Dust and grime collect here too, and a clean sill makes the whole window look fresher. If you need tips on cleaning screens specifically, we’ve got a helpful guide on how to clean fly screens.
Preventing Salt Spray Damage on Coastal Properties
If you live near the beach, regular cleaning is your best defence against salt damage. But there are a few extra tricks that can help between cleans.
After gentle rain, you might notice your windows look cleaner. That’s because the rain rinses away some surface salt. You can replicate this by giving your louvres a quick rinse with a garden hose every few weeks. Just make sure to wipe them dry afterwards to prevent water spots.
During particularly windy days when the sea breeze is strong, close your louvres to minimise salt exposure.
Common Mistakes That Leave Streaks (or Worse)
Here are some mistakes to avoid when cleaning your louvre windows:
- Don’t clean in direct sun. When it’s hot, cleaning solution dries too quickly and leaves residue. Pick an overcast day or clean early morning or late afternoon.
- Don’t skip the rinse. If you leave soapy water or vinegar on the glass, it will dry and create a film. Always rinse with clean water.
- Don’t forget to dry immediately. Excess moisture sitting on aluminium frames can lead to corrosion over time.
When to Call in Professional Help
Sometimes, cleaning reveals bigger problems. If you notice corroded mechanisms, blades that won’t close properly, or frames with significant pitting, it might be time for an upgrade rather than just another clean.
At Perth Window & Door Replacement Company, we supply louvres that meet AS 2047 requirements for water penetration and air infiltration, being built to handle Perth’s salty, dusty climate without constant fuss.

Keep Your View Clear and Your Home Fresh
Cleaning louvres doesn’t have to be a cleaning marathon. With the right tools, a simple cleaning solution, and a regular routine, you can keep your windows sparkling and your mechanisms working smoothly. Remember: warm water and mild detergent for routine cleaning, vinegar solution for stubborn grime, and always dry immediately to avoid streaks.
For coastal homes, more frequent cleaning (every 3-6 months) prevents salt damage. And if your windows are showing their age, modern louvre systems offer significantly better performance with less effort.

Frequently Asked Questions
How do you remove cloudy film from glass windows?
A vinegar-water solution is most effective. Spray or wipe it onto the glass, let it work for a minute, then wipe clean. For severe buildup from salt or minerals, you may need to repeat or use a specialised glass cleaner. Always finish by rinsing and drying.
Do louvre windows seal?
Yes, modern louvre windows seal very well. Quality systems can achieve air infiltration rates 40 times better than older jalousie windows. Proper maintenance and occasional weather-stripping replacement ensure they continue to seal effectively.
How to seal up jalousie windows?
Add vinyl slat edging or adhesive weather-stripping along blade edges to tighten gaps. For extra insulation, consider interior acrylic storm inserts. These solutions are removable and relatively inexpensive compared to full window replacement.
How to make louvre windows soundproof?
Complete soundproofing is difficult with louvres since they’re designed for ventilation. However, you can reduce noise by adding weather-stripping to tighten gaps and installing interior acrylic inserts. For significant noise reduction, upgrading to modern sealed louvre systems is most effective.
