Outdoor Cleaners MSC 2022 award

30 Seconds: New Zealand’s Favourite Outdoor Cleaning Products

Whether you’re washing your windows, your roof or your driveway, Kiwis say 30 Seconds is the product to use, as this year’s winner of Canstar Blue’s Most Satisfied Customers Awards for Outdoor Surface Cleaners and Outdoor Window Cleaners .

Too often, after a long week of work, weekends are spent working on the house. Scrubbing walls with outdoor cleaners, water blasting the driveway, cleaning windows … before you know it, it’s Monday morning and you’re back in the office.

And when it comes to cleaning  around the home, scrubbing down outdoor surfaces can be some of the most challenging jobs on the checklist. Algae, lichen, moss, mould and mildew can all plague our home’s exterior walls, roofs, decks, fencing, pavers and more. Without the proper cleaning products, you can scrub tirelessly to little avail.

Which is why, here at Canstar Blue, each year we ask everyday Kiwis for their opinions on the best outdoor surface and window cleaners, to find the products that take the hard work and hassle out of grimy cleaning jobs.

30 Seconds: NZ’s favourite outdoor surface and window cleaners

This year, to find which products are the nation’s favourite, we surveyed a total of 736 customers who had purchased and used either an outdoor cleaning product or exterior window cleaning product in the past 12 months

We asked them to evaluate the products across the following categories:

  • Overall Satisfaction
  • Effectiveness
  • Value for Money
  • Environmentally Safe/Friendly
  • Ease of Use
  • Packaging

And according to Kiwis, no matter the job at hand, 30 Seconds is the way to go! In our 2022 surveys, it is the winner of both our outdoor cleaning awards – Most Satisfied Customers | Outdoor Surface Cleaners and Most Satisfied Customers | Outdoor Window Cleaners.

About 30 Seconds

The 30 Seconds range of home cleaning products has been on the shelves of Kiwi homes for over 25 years. Every day, 35,000 litres of 30 Seconds cleaning products are bottled in Matamata, before being shipped across the country and the world.

In this year’s award surveys, 30 Seconds achieves excellent ratings. It earns a clean sweep of 5-Star results for Outdoor Surface Cleaners and a near clean sweep of top ratings for Outdoor Window Cleaners.
