Aluminium vs uPVC Window Cleaning

Tired of Streaks, Spots or Black Marks on Your Windows?

If you’ve noticed black streaks running down your windows after a clean, especially on aluminium frames, you’re not alone.

Many homeowners across Coleraine and the North Coast experience this issue—and it usually comes down to poor cleaning methods, not the windows themselves.

At TrueClean NI, we specialise in professional window cleaning for both aluminium and uPVC frames, delivering a spotless, streak-free finish every time.

Aluminium vs uPVC – Why Cleaning Method Matters

Not all window frames are the same—and using the wrong technique can leave your windows looking worse after they’ve been cleaned.

Aluminium Frames

Modern and stylish—but they require expert care.

• Can release black residue during cleaning

• Dirt builds up in edges and seals

• Need a thorough clean on the edges

👉 Cleaned properly, they look incredible
👉 Cleaned poorly, they leave streaks and marks

uPVC Frames

Common across homes in Coleraine and surrounding areas.

• Easier to maintain

• Still hold dirt in frames and vents

• Can cause spotting if not rinsed properly using water fed pole method.

• Polished by traditional window cleaning will shine brightly.

👉 Simpler to clean—but still needs professional care for best results

⚫ Why Do Black Streaks Appear After Cleaning?

This is one of the biggest complaints we hear.

Black streaks are caused by:

• Built-up dirt in frames and seals

• Oxidation from aluminium frames

• Rushed or incomplete rinsing using water fed pole method

• Frames being cleaned after the glass

👉 The result? Dirty water runs down onto freshly cleaned windows
