Able to be used on all stonework and concrete surfaces, this product will get even the filthiest block paving looking pristine once more, and it does it with relative ease.

This patio cleaner solution can also be used on almost any surface, from stone to concrete, terracotta, and even fencing. Some people use it on their UPVC windows, so this may be the best patio cleaner in the UK due to the variety of things it can do.

How to Choose the Right Patio Cleaner

So, you want to buy the best patio cleaner in the UK, but what should you be looking out for when it comes to choosing the product? Well, there are several steps to look out for.

What Can it Clean?

When looking to buy a professional patio cleaner, you need to know what your patio detergent is capable of cleaning. With this point, we don’t mean mould algae or anything else like that. Instead, it’s the items it can be used on.

While you can also apply some liquid patio cleaners to garden furniture and wood, that’s not always the case. While one may work well on paving slabs, it may destroy wood, so you cannot then apply it to the wood decking or a fence.

Be sure that you get the best patio cleaner for your own individual needs. The best patio cleaner will give a deep clean to all your items, rather than having to rely on different options.

Does it Need Pressure Washing?

After applying the patio cleaner to the surface, you must know how to deal with things. Do you simply spray and then leave it? Does it need a pressure washer to remove the debris that it will loosen off? Do you even need a specific pressure washer to deal with the cleaner in the first place?

A number of options require minimal fuss. Even the strongest patio cleaner on the market can be dealt with via a simple rinse to remove the dirt it has created.

How Do You Apply It?

You must also pay attention to how you apply it in the first place. While a spray patio cleaner is self-explanatory, most will require diluting into the right solution before adding to those paving slabs.

This diluting process applies to every version, not just a heavy-duty patio cleaner. Diluting becomes even more important if dealing with something such as Indian sandstone. If applied at concentrated levels, the chemicals could eventually damage the stone, so follow the instructions carefully.

Is it Safe?

This point is pretty obvious, but you must be aware as to whether or not this product is safe to use around pets, children, or even if it could damage aquatic life. While most are indeed environmentally friendly, there’s more to it than just stating it’s eco friendly on the bottle.

You have to remember that this is a product designed to remove dirt and mould. It contains chemicals for the algae remover to really work. However, the best patio cleaners should be safe around everyone, and there shouldn’t even be too much of a smell from it either.

Does it Keep Mould and Algae Away?

Cleaning away that moss mould lichen algae concoction is one thing, but will the cleaner be capable of keeping all of those horrible things from just growing back immediately?

That is perhaps something you want to think about. You see, the products we have listed are not just washing up liquid in a spray bottle. They are designed for you to spray and walk away to let them do their job.

However, some do contain chemicals that help to slow down the development of all those nasty things on your patio, so it will make life easier for you in the long term.

Things to Avoid

Finally, there are undoubtedly things to avoid when it comes to buying these products. So, what should you look out for?

As we said earlier, avoid buying something that cannot clean everything you need. If it focuses on slabs and not brick, and you have brickwork to clean, then there are other options out there that will be suitable.

Also, be aware of the type of stone you have. The harshness of chemicals may damage something such as Indian sandstone, so pay attention to any warnings as to where or how you can use it.

The last thing is to avoid buying too little. A product should be able to tell you how this cleaner can cover a large area, so pay attention to those details. It will mean a better end result.

There’s nothing complex about choosing the correct patio cleaner that suits your needs. All that’s required is to understand what is to be cleaned, how often you need to do it, the method to be applied, and how long it will last.

Any of the products listed above are more than capable of removing algae and mould from your outside space.

Overall Conclusion

Finding the best patio cleaner in the UK is very easy to do as there are so many options out there to choose from that are all capable of doing a fantastic job. However, for us, the best patio cleaner has to be Patio Magic!

This is the best patio cleaner as it ticks all the boxes. It is safe to use, easy to use and delivers results. There really is nothing that it cannot do. Yes, you do need to be patient to give it time to work, but it will all be worth it in the end.

A patio cleaner will become an essential tool for your garden. There’s no need to worry about the chemicals that are used, as the modern versions are significantly safer than the older versions from years ago. There are so many rules and regulations that must be followed that each manufacturer needs to be careful as to what they put into it.

So, feel free to choose any of the cleaners we have spoken about here. They are all excellent at what they do, and there’s no doubt that they will make a significant difference to the appearance of your patio.
