Best Deck Cleaner

Looking to buy the best Deck Cleaner? Check out our guide below and you’ll be well-placed to select the correct one for your needs.

Wooden decking may be found in the gardens of millions of homes across the United Kingdom. A decked area in your garden is the ideal way to create a patio that is both modern and in keeping with the natural aspect of your yard. They’re also less difficult to install than patio or concrete slabs. Maintaining a wooden deck area, on the other hand, isn’t always simple; they need to be treated once or twice a year to avoid rotting or becoming spongy. You’ll need to be able to clean your deck in order to perform a decent job of treating and caring for it. Not only that, but decking sections that are part of main walkways or are overhung by trees or shrubs will collect trash and dirt, resulting in a slick film forming on the top of the deck, which can be dangerous!

You need a deck cleaner whether you’re intending on treating your decking area or you’re tired of slipping every time you try to walk to the remainder of your garden! The difficulty is that numerous sorts of deck cleaners are available depending on the work at hand, so you’ll need to know exactly what you’re looking for. This is why we’ve put together a list of the top deck cleaners on the market right now, as well as the crucial features to look for.

Deck Cleaner Types

You’ll be able to choose between two sorts of deck cleaners: basic cleaners and stripping cleaners. Because they are created to perform very different things, you must be certain that you are purchasing the correct one.

Standard deck cleaners are made to do nothing but clean your decking, and they’ll do an excellent job of it. These cleaners are ideal for anyone who has a decked area that is in good condition and has recently been painted, but has become covered in dirt and debris, or possibly stained! They are made with strong enough ingredients to get the job done, but gentle enough not to damage the decking and varnish that is already there! They’re great for getting rid of soil, moss, algae, stains, and lichen from your decking, so it’ll appear brand new and be more safer to walk on.

A stripping deck cleanser is the second sort of deck cleaner. These deck cleaners will clean your patio area similarly to the ones discussed above, but they are built to accomplish much more. These cleaners, which contain harsher, more caustic compounds, will continue to operate after they have cleared the debris from your patio area. They will also remove most surface paints or varnishes from your decking, allowing you to sand and refinish it. This is wonderful if you want to alter the colour of your decking, or if it is looking particularly weary, or if you simply want to complete your annual maintenance properly so it lasts longer! These are also called as preparatory cleaners because they aid in the preparation of your decking for painting! The only drawback to using a stripping deck cleanser is that you’ll need to be prepared to treat your hardwood decking again once it’s been exposed to the outdoors.

Cleaning Methods

Different deck cleaners function in different ways to get the job done, so you’ll have to use them in different methods as well. This is crucial to look for, not only because you need to know how much work you’ll be doing, but also because using your cleaner incorrectly could result in damage to your decking!

Step 1 – Applying the deck cleaner for the first time is critical to completing the job correctly. You’ll need to calculate how much solution you’ll need and dilute it with water (for most cleaners). Some may be poured onto your decking with a watering can or a jug, while others will require the use of a specific spraying tool (such as a paint sprayer) to achieve even application. There are even some cleaners that require the use of a pressure washer, so you’ll need one on hand to complete the task.

Step 2 – Scrub or Soak – Some deck cleaners will require scrubbing into the top layer of your decking, which will require more labour on your part but will allow the deck cleaner to get to work much faster! Other deck cleaners, on the other hand, only need to be put onto the deck and left to work.

Step 3 – All deck cleaners will require a specific amount of time to do the task. This is crucial to check for since you won’t be able to securely walk over your deck during this period without jeopardising the work that has already been done! Some jobs will take only a few minutes to complete, while others will require several hours!

Step 4 – After you’ve completed the work, rinse off the deck cleaner to prevent harm to your decking. Some people will just need one rinse with a watering can, while others will require a much more thorough cleaning, especially if the substances are more potent.

Should I Use a Deck Cleaner or a Pressure Washer?

When you’ve decided on the type of cleaner you want and the different surfaces you want to clean, as well as the cleaning procedure that will work best for you and the amount of work you want to put in, here are some of the main factors to consider when buying.

Ingredients – The first thing to look for in your deck cleaner is the major ingredients. The most common one is bleach, which will be capable of removing the majority of the trash and grime from your patio. Stronger bleach or bleach with larger concentrations can be found in more stripping deck cleansers.

Environmentally friendly – If you care about the environment or simply don’t want to harm all of the plants in your garden by rinsing off your deck cleaner, you may want to look for a deck cleaner that uses something other than bleach. When it comes to keeping your pets, small children, and plants safe, oxygen bleach is a great option!

Neutral pH cleaners — We’ll go over this in more detail later in the post, but if you don’t have time to apply a brightener after your cleaning, search for one with a pH level as neutral as possible to avoid long-term harm to your decking.

Concentration ratio – All deck cleaners will need to be diluted, but the ratio used influences the amount of value for money you will get! The more water and less solution, the greater value for money!

Effectiveness – Consider the strength and effectiveness of your cleanser. Some claim to be able to give your wooden decking a beautiful sheen after only one wash, while others claim that it takes several applications to get the job done!

These are the qualities to look for if you want the most value for your money and the best deck cleaner to keep your deck safe while cleaning it. They were only discovered in the greatest deck cleaners!

Powder or liquid – There are two types of deck cleansers available: liquid solutions that may be diluted in water and powder/granular cleaners that must be blended with water to create a cleaning solution. Powders normally last longer and are easier to store, but liquid cleaners are more reliable because they don’t require dissolving.
Protective coating finish — If you’re buying a conventional deck cleaner without the stripping feature, seek for one that has a polymer coating that will cover the planks and provide extra protection until you’re ready to treat your decking again.
Friendly to aquatic and plant life — If you have plants, shrubs, or a pond near your deck, you risk hurting them in the process of keeping it clean and tidy. Look for cleaners that say they’re made with natural chemicals that are gentle. Remember that if any of your deck cleaner gets into the soil, it has the potential to be absorbed by the roots of your plants.
Brightener – After using a deck cleanser, a brightener is utilised to balance the pH levels of your deck area. It’s always a good idea to get one of these along with your deck cleaning. Many deck cleaners, varnishes, and oils can cause your decking’s pH to become overly acidic or alkaline. Your hardwood planks will warp and deteriorate much sooner than necessary as a result of this! Brightener solutions will bring this level back to normal, allowing your wooden decking to last longer!
Material compatibility – Determine which types of decking your cleansers are capable of cleaning. Some will only work on wood, while others will be able to work with PVC, vinyl, and composite materials.

Most Commonly Asked Questions
When it comes to deck cleaners, how long should they last?

This is highly dependent on the surrounding region of your sundeck. If it’s a high-traffic area that leads to the rest of your garden, muck on the bottoms of shoes will make it much filthy much faster. You’ll also notice that a decking area beneath trees may mark more easily due to sap and leaves falling. However, if you choose a decent quality deck cleaner with a polymer covering, you may expect it to last for up to a year.

When should a deck cleaner begin working?

Many deck cleaners, especially those that require you to scrub them into the surface, will make a noticeable change in your yard within 10 minutes. Whether you leave it for an hour or overnight, this will gradually improve over the course of the therapy! However, we discovered that several cleaners, even after being rinsed, continue to brighten a decking area over the next few days!

Do I need to clean my hardwood decking before staining it?

You are not need to use a deck cleaning prior to staining your hardwood decking, but there are numerous reasons why you should. To begin, it is beneficial to remove all dirt and debris from your decking in order to ensure that your new staining will appear nice and even. This also means that, despite the fact that you’ll have to spend more time planning, you’ll be able to finish the work faster! Not only that, but if you choose a deck cleaner that removes the old varnish or paint, you’ll have your woodwork prepped and ready for the task! The greatest deck cleaners will actually open up the pores of the wood, allowing them to absorb and store the stain or varnish you’re using!
