The two aspects that I had mentioned stay true only when the deck is well maintained. Cleaning your deck with an appropriate cleaning solution is the ideal way of keeping your deck in its pristine glory, which consequently gives your house an aura of grace. So, a deck cleaner is something that every home should have. This would ensure that your deck does not feel the effects of changing weather and keeps looking as good as new for a longer period of time.

Before you start using the deck cleaner, you need to make sure that the unwanted growth such as weeds or grass is removed from the surface. The surface should be swept well so that any sand, dirt, or debris is removed before the application of deck cleaner. For this, you can either use a leaf blower or the good old broom as long as they serve the purpose. Once the surface has been swept clean, you need to assess if there is a need to apply a water sealer. A simple test can help you determine this. Pour a small quantity of water on the surface. If it beads up into tiny droplets, that is a clear indication that you are all set to proceed with applying the deck cleaner. However, if the water soaks into the surface of the deck, it may be time to use a water sealer.

Having taken a look at what has to be done, now let us dwell into which deck cleaner needs to be used. Factors to be considered while buying a deck cleaner include its effectiveness, need for additional agents, the duration for which its effect lasts and finally any toxic effects it may have on humans, pets and the environment. Let us take a look at some of the best deck cleaners available and understand if they are suitable for your requirements.

The first deck cleaner that we are going to take a look at is the one from Rempro. This cleaner can be used to clean hard surfaces such as path, patio, fence, brick paving, stone and decks. It’s quite effective as a patio cleaner but I would follow the link provided is better. It is ideal for a surface that has been infested with algae and floral growth. This deck cleaner also adds up as algae, mould and moss killer. While being hard on those unwanted growths, it contains no harmful biocides that would remain dangerous for kids, and pets even when dry. This makes this deck cleaner suitable for both internal and external use.

Rempro decking cleaner solution can be diluted to make 20 litres of total sprayable product from the 5 litres provided in the can. The treatment area that can be covered is approximately 10 square metres per litre when diluted. So a 5 litre can would be able to cover about 200 square metres when used in the diluted form. It has a long lasting effect. The results can last as long as up to a year. Some notes about the usage include taking of excess growth before application. Use a brush to apply it uniformly. However, for best results, it is recommended to use a low pressure spray. Keep the solution away from grass, plants and flower as it can cause scorching. You will be able to see visible results with 2 to 4 days after application and secondary effects can be realised weeks later. It would take about 3 to 4 hours for the product to be watertight and up to 24 hours to be fully cured depending on the temperature and porosity. As with most cleaning solutions, the equipment used needs to be washed with warm water before use for best results. Please make sure that you read the product and safety information before use.

If you are looking for a solution that has a lasting effect and can be used on concrete, tiles and stones this product from Rempro has the answer.

2. Jeyes decking power cleaner

Jeyes Decking Power Cleaner, 4 Litre
2.9 out of 5 stars ( 3 customer reviews )

The next deck cleaner that we are going to review is the Jeyes decking power cleaner that comes in a 4 litre can. This is a deck cleaner that is best suited for wooden surfaces. Let us take a look to determine why one has to buy this deck cleaner.

As far as use is concerned much similar to the earlier deck cleaner that we discussed, the Jeyes decking power cleaner can be used on patios, paths, blocks and bricks as well. It can be used on hard surfaces as well as wooden surfaces. It actively removes algae moulds and mildew from the surface and restores your timber to the best possible state. Being a disinfectant it is capable of killing up to 99.9% germs and restores natural colour to your wood by preventing re-growth of algae and other unwanted microbes leaving your deck looking new for a long time. One can of the Jeyes decking power cleaner can cover an area of up to 198 square metres.

As with all pesticides, please read the product description and safety information fully before using it. This product can cause skin irritation and serious eye damage. So, please make sure that you wear all the required safety equipment such as eye gear, gloves and safety vests before you start using it.

Why would you buy the Jeyes decking power cleaner? It is ideal to neutralise and prevent re-growth of algae, mould, and mildew on all wooden outdoor surfaces including decking and fencing as well as hard surfaces. If you intend to restore the colour of your timber, this is the best choice.

3. Ronseal DC decking cleaner

Ronseal DC Decking Cleaner 5 Litre
4.3 out of 5 stars ( 77 customer reviews )

We took a look at two deck cleaners that do the job of cleaning the deck as well as eliminating microbes such as fungi and algae and so on. One was best suited for hard surfaces while the other had an edge on timber. Now, let us take a look at one such deck cleaning solution that is again ideal for wooden surfaces. This is the Ronseal DC decking cleaner. What makes the Ronseal DC decking cleaner unique? Let us take a look.

The fast acting formula of the Ronseal DC decking cleaner removes dirt, fungi, algae, mildew, stains and grease from the wooden surface. It is also known to review the timber to its pristine glory. The 5 litres of Ronseal DC decking cleaner provided in the can is enough to clean a deck area of 20 to 24 square metres. Apart from cleaning the outer surface and removing the microbes on them, the Ronseal DC decking cleaner also opens the pores in the wood so that it allows maximum adhesion of coatings. This makes the decking finish last longer. So, here is what makes the Ronseal DC decking cleaner different from the other two that we reviewed. It has the chemical ingredients that ensure that the decking finish sticks to the wooden surface strongly. I highly recommend after cleaning with Ronseal DC decking cleaner you then seal with Ronseal Quick Drying Wood Stain and this is not to be confused with shed and fence stain.

The anti-fungal and microbial ingredient benzisothiazolone is present in this product and acts as the wood preserver. This can cause allergic reactions. So, it is imperative that any form of contact with the skin or the eyes is avoided and in case there is any such contact, medical advice should be sought immediately. Read all the literature that comes with the product thoroughly before use and take all precautionary measures as required. This product is the best suited to review weathered decking and prepare the wooden surface before the coating is done.

4. CUPRNOL 5083456 decking cleaner and exterior wood care

The CUPRNOL 5083456 decking cleaner is a detergent based cleaner that is specially formulated to kill algae and mould, while being able to detach the grease and dirt from the surface. It also has a sterilising effect that prevents the regrowth of these microbes. This makes it best suited for cleaning and cleansing even patios and stone works. It can be used to prepare the decks before the oiling or staining activity.

This can be applied using a brush or bristle brush. Coming from a brand that has over 70 years of experience in wood care, CUPRNOL 5083456 decking cleaner contains 2.5 litres of the water based cleaning solution that can easily cover 7 to 15 square metres per litre depending on the condition of the deck.  The average drying time is 16 hours. This can vary depending on the weather condition and the nature of the surface. Again, the CUPRNOL 5083456 decking cleaner is ideal to prepare your wood for all kinds of treatments. You can even use this on sheds(follow it up with this shed preservative), fences, and other garden furniture. They sell this in 23 different colours and by that itself you can understand that experience matters.

5. Rustin decking cleaner

The last one on this list is a decking cleaner from the house of Rustin’s, a reputed brand in wood care products. Having an experience in excess of 9 decades, I think we can completely trust them with the quality of their product. The Rustin’s decking cleaner 4 Litre – (DECL4000) provides ultimate protection to your garden decking. The Rustin decking cleaner is a compound that is made of special cleansing agents. This can be used to remove dirt, grease, algae, and even mildew from the surface of your deck. It is also best when it comes to reviving a weathered garden decking. The Rustin decking cleaner – (DECL4000) suits well for both old as well as new decks. It can also be used to clean fences, cladding, window frames and other exterior wood work.

As far as the use is concerned, before application, you need to make sure that all loose dirt, grease, mould and mildew are removed using a deck scrubber or a garden broom. The Rustin’s deck cleaner can be applied using a brush, a watering can or a sprayer, but please ensure to shake well before use. 10 minutes after application, use a stiff garden brush or deck scrubber to scrub the surface. This will remove the debris from the surface. After scrubbing, please wait for 30 minutes and then rinse the surface with water using either a garden hose or a stiff broom. The process can be repeated as necessary. The drying time is at least 24 hours, post which you can go for other treatments. The can contains 4 litres of Rustin’s deck cleaner and is good enough to cover 20 to 25 square metres of the decking surface.

If you have planned a series of treatment for your wooden deck and need a solution that can be used to prepare the deck before the actual treatment starts, the Rustin’s deck cleaner is the one you should buy.
