The Top 3 Causes of Dirty Windows in the Perth Hills

Living in the beautiful Perth Hills offers a unique lifestyle, but it also comes with a unique set of challenges for keeping your home's exterior clean. The combination of dense bushland, weather patterns, and local activities means windows in suburbs like Kalamunda and Mundaring get dirty in a very different way to their coastal counterparts.

As local cleaning experts, we've seen it all. Here are the top three culprits behind dirty windows in the Perth Hills and how to deal with them.

1. Leaf Tannins and Organic Stains

The stunning gum trees and native flora are a hallmark of the Hills, but they are also the primary source of stubborn window stains. When leaves, bark, and blossoms sit on your glass and get wet from rain or morning dew, they release **tannins**.

This is the same natural compound found in tea, and it leaves behind a distinct, reddish-brown stain that bonds tightly to the glass. A simple wipe won't remove it. A professional clean using specialized solutions is often needed to break down these organic stains and restore the clarity of your glass.

2. Wood Fire Smoke and Soot

There's nothing better than a cozy wood fire during a chilly Hills winter. However, the smoke and fine soot particles that come from your chimney (and your neighbours') eventually settle on your exterior windows. This creates a greasy, grey film that can be very difficult to remove without smearing, especially when combined with moisture.

This type of grime requires a more robust cleaning approach than standard dust, often needing a thorough scrub with a professional-grade cleaning solution to cut through the oily residue.

3. Pollen and Fine Dust

During spring and the dry summer months, the air in the Perth Hills is thick with pollen from the surrounding bushland, as well as fine red and brown dust. This settles as a thick, hazy layer on your glass, obscuring your view and making your home feel dusty and unkempt.

Like coastal salt spray, this fine particulate matter needs to be properly lifted and rinsed away, not just wiped. A professional clean ensures all this abrasive material is removed safely without scratching the glass.
