What Are The Best Decking Cleaners On The UK Market?

Your yard or outdoor space should be an extension of the interior; a place you can relax and enjoy every single day. That’s why it makes total sense to build or update you deck. Decking not only provides a neat, peaceful place to retreat, it also boosts the value of your home substantially. In truth, a deck will make any space more beautiful and serene.

But while decks are a great addition to any garden or yard, they also require some cleaning and maintenance to ensure the decking looks great and lasts longer. In the UK, wood is the most popular type of decking.

However, other materials are catching up including plastic, composite, and aluminium decking. But no matter what material your deck is made up of, no one wants to hose and scrub decks and patios all day.

This is where the best decking cleaner comes to the rescue. Typically applied through a sprayer, decking cleaners are designed to remove dirt, blemishes, and other unwanted materials from the surface of a deck.

These unwanted materials include oxidation patches, algae, fungus, lichen, moss, and weather stains. Depending on what material your deck is made up of, decking cleaners come in a wide range of concentrations that may or may not need dilution prior to the application.

We’ve gone through bottles of decking cleaners to find the best and most efficient ones – as well as some key features to watch out for. For instance, oxygenated deck cleaners have grown in popularity over the years because they contain an environmentally friendlier bleach called sodium per-carbonate.

Similarly, it helps to go for a biodegradable decking cleaner to make sure you don’t wash off lingering chemicals into your garden.

Jarder Spray and Leave is fully biodegradable, and contains zero acids and bleach.

But that’s not all the cleaner from Rustins does. It’s also formulated for reviving weathered outdoor decking. For a 4 litre bottle, the price range is also quite budget friendly. One bottle is enough to clean an area of about 25 square metres.

The growth of algae and moss on decking not only detracts from the appeal of your garden; it can also get dangerous during cold months when patios and decks become super slippery.

As a bonus, the cleaner contains no acid, no bleach, and is fully biodegradable.

Frequently Asked Questions

Q: How to use decking cleaner?

  1. First of all, give your decking a thorough clean. Scrape off any large areas of moss or mould, then take a stiff bristled brush to the decking, making sure to get right into the grooves. You can use a pressure washer for this if you have one.
  2. Take your chosen decking cleaner and apply it to the decking with a watering can. Scrub the deck straight after with a brush or broom, once again getting it right into the grooves.
  3. Leave it to stand for at least 15 minutes to work its way into the grain.
  4. Rinse the decking, using either a watering can filled with clean water, a hose or a pressure washer.
  5. Allow at least two days for the decking to dry out thoroughly before you apply any stain or paint.

Q: How does decking cleaner work?

Decking cleaner is not a detergent as such; not like the type you use to wash your dishes, but it does contain cleaning agents. You can get decking cleaners that use oxygen to clean, the bubbles creating a fizzing effect that lifts dirt and grime.

Some decking cleaners do contain a percentage of bleach – although it is an effective cleaner, this type of decking cleaner is not recommended as it is toxic to the environment. You can even make your own decking cleaner, using a mixture of water and washing powder!

Q: Where to buy decking cleaner?

The vast majority of large hardware stores will stock a wide range of decking cleaners, so you can select the one that suits your needs the best. You will probably also be able to find a selection at smaller hardware stores, meaning that you won’t have to travel as far.

If you prefer to do your shopping from home then the internet will show you a huge array of products for cleaning your decking – just take your pick!
