A previous winner of Canstar Blue's Outdoor Glass Cleaner Award, once again 30 Seconds excels in our award ratings, securing a near-perfect set of scores from its Kiwi customers.

30 Seconds is the only glass cleaner to achieve a 5-Star Overall Satisfaction rating, a score it achieves in every category except Packaging, for which the brand earns 4 Stars.

30 Seconds Window Wonder Outdoor Glass Cleaner not only removes dust, grease and grime from glass, it's also suitable for other hard non-porous surfaces, such as stainless steel and chrome.

Key features include:

  • Hose-end applicator powerful enough to reach second-floor windows
  • No squeegeeing or scrubbing
  • Streak-free formula
  • Able to reach second-storey windows
  • Also available in 5l refill concentrate packs

2. Simple Green

Simple Green has one outdoor window cleaner in its range: Hi-reach Exterior Window Cleaner, which promises a streak-free finish.

The hose-spray dispenser is powerful enough to reach second-storey windows and the formula is non-toxic.


3. Wet & Forget

Wet & Forget's Window Witch hose-spray dispenser provides an eight-metre reach.

The product's cleaning ingredients dissolves grease and grime, while water softeners and a sheeting agent work to ensure a streak-free finish.

The product is available in a 2l spray dispenser, which provides coverage for up to 600m² of glass, as well as 2l refill packs.


Choosing the right outdoor window cleaner for you

It's as clear as sparkling windows that, when it comes to rating window cleaning products, one quality is paramount: their effectiveness.

In our survey, 38% of respondents base their satisfaction with their choice of window cleaning product on how effectively it cleans.

Ease of Use is also an important factor, as spray applicators need to be easy to control and powerful enough to reach second-storey windows.

And as always, Value for Money is important, too – cited by nearly a quarter of those in our awards survey.

Here's the full rundown of what Kiwi consumers say are the main things they consider when rating their outdoor window cleaners:

  • Effectiveness: 38%
  • Ease of Use: 30%
  • Value for Money: 21%
  • Packaging: 11%
