How to Clean Your Windows Like a Pro

As professional window cleaners, we believe everyone deserves a crystal-clear view. While nothing beats a professional service for a perfect, long-lasting finish, we understand that sometimes you want to tackle the job yourself. The secret to avoiding those frustrating streaks isn't a magic spray—it's using the right tools and the right technique.

This in-depth guide will walk you through the exact method professionals use to get a flawless, streak-free shine every time.

Step 1: Gather the Right Tools (The Professional Kit)

Forget paper towels and generic glass sprays. To get a professional result, you need professional tools. You can find these at specialty cleaning supply stores or even the trade section of Bunnings.

• A High-Quality Squeegee: This is your most important tool. Invest in a good one with a sharp, flexible rubber blade.
• A Microfibre Applicator (or Scrubber): This holds a lot of water and is perfect for scrubbing the glass without scratching it.
• Two Buckets: One for your cleaning solution and one for clean rinse water.
• A Few Drops of Dish Soap: That's it! A high-quality dish soap like Morning Fresh is all you need.
• Lint-Free Cloths: Old surgical towels or a high-quality microfibre glass cloth are perfect for detailing the edges.

Step 2: The Professional Cleaning Process

Follow these steps for a perfect finish:

1. Prepare Your Solution: Fill one bucket with a few litres of cool water and add just a few drops of dish soap. You want it to feel slightly slippery, but not foamy. Fill the second bucket with clean rinse water.
2. Wash the Window: Dip your microfibre applicator into the soapy water, squeeze out the excess, and thoroughly scrub the entire surface of the glass. Make sure to get into the corners to loosen all the dirt.
3. The Squeegee Technique: This is the key to a streak-free finish. Start at the top corner of the glass. Place your squeegee at a slight angle, overlap each pass by about an inch, and wipe the rubber blade with a clean cloth after every single pull. This prevents dirty water from being dragged across the clean glass.
4. Detail the Edges: Use your lint-free cloth to wipe away any remaining water from the edges of the pane and the window sill.

The #1 Mistake to Avoid in Perth

Never, ever clean your windows in direct, hot sunlight. The sun will cause your cleaning solution to evaporate almost instantly, leaving behind a residue of soap and dirt that is impossible to remove without streaks. Always work in the shade or on an overcast day for the best results.
