The well-known Jeyes Fluid is one of the best patio cleaning products suitable for most homeowners. It is a multi-purpose outdoor cleaner best used on paths, patios, driveways, flower pots, and other hard surfaces.

Jeyes Fluid

Features

This formula kills up to 99.9% of germs, removes grease and dirt, disinfects hard surfaces, and even unclogs drains. So, is Jeyes Fluid good for cleaning patios too? You bet! In fact, they even have a Royal Warrant and supply the Royal Household with their products.

The coverage area you can expect from a bottle of Jeyes Fluid varies greatly because different tasks call for different dilution recipes. Different tasks also come with different application processes but with patios, you can expect to apply the cleaning solution, wait 30 minutes, and then scrub.

Be aware, though, that this multi-purpose cleaner should be kept away from plants and pets. It also does not eliminate moss and may discolour decks or plastic.

What to Look for in a Patio Cleaner

That’s all for our patio cleaner reviews. Now let’s expand our understanding of what makes the best patio cleaners, and how to choose the best product for your specific cleaning requirements.

Patio Surface Material

One of the first questions you should ask yourself is, “What type of surface or surfaces am I trying to clean?” This is because not all materials can handle all types of cleaners and some work best on certain materials and not others. For example, Indian sandstone and wood may be better served by different cleaning products, however, some multi-purpose, less abrasive cleaners will work on all outdoor surfaces.

Most patio cleaners strongly advise against using their product in an indoor setting but there are exceptions to this rule if you want to minimise the overall number of cleaners you keep around your home.

Area to Cover

We also recommend paying attention to the coverage area a single bottle of cleaner can accomplish. Thus, you don’t accidentally run out of product halfway through cleaning your patio and ultimately delaying the results you are trying to achieve.

Keep in mind, many products are concentrated, making it harder to tell by looking at the size of the bottle alone. They also feature differences in concentration level and have different mixing formulas.

Cleaning Process

When it comes to the cleaning procedure, not all patio cleaners are made the same. Some cleaners require scrubbing, some need to be rinsed off after a short time, and others still can feature the ability to simply be sprayed on with a garden sprayer or watering can and left to do their job unattended. How much work are you interested in doing to keep your patio clean? In our opinion, the less work required the better.

Active Ingredients

We recommend paying attention to whether or not a patio cleaner possesses harsh chemicals. Ideally, you’d want a product that won’t stain or discolour surfaces. Some outdoor materials that you wish to clean are more fragile than others and as a result, do not tolerate harsh chemical application well, or without adverse side effects. Stay away from cleaners with harsh chemicals if you want to clean and maintain decks, furniture, wood, or hard plastics.

If you have pets or small kids it is also important to choose a product that doesn’t contain caustic or harsh chemicals. Most of the products on our patio cleaner list are pet- and kid-friendly and we make sure to let you know when they are not.

Other Things to Consider

If you’re cleaning your patio for the first time, here are pro tips that will help speed up great results.

What is the Best Way to Clean a Patio?

The best way to clean patio surfaces depends on the tools you have at your disposal and how much physical labour you want to commit to the process. For example, if you’re wondering if you can use bleach to clean a patio, the answer is yes. However, it will require an intensive scrub session.

Using a pressure washer, or jet washing, is another way to clean your patio but if you don’t have one there is always the patio cleaner. Many of the patio cleaners available can be sprayed on and forgotten which is the easiest way, in our opinion.

Combining a patio cleaner with a pressure washer is a great way to speed up the process and get your patio clean and looking like new again in almost no time at all. What is the best patio cleaner to use with a pressure washer? It depends what type of surface you are working with.

Cleaning Power

Different patio cleaners are better suited for removing different types of organic materials. When choosing a product to clean your patio we recommend knowing what you’re trying to remove. Do you have black spot mould, moss, lichens, algae, mildew? Most products do at least a fair job removing all of these unwanted growths but some are better equipped for mould or dirt than others. Hence, make sure to choose a product with the appropriate cleaning power for your needs.

Which Patio Cleaner Will You Choose?

By now, you should have all the information needed to determine the best patio cleaner for your home but before you make a final decision, let’s review why our Editor’s Choice is our top pick.

Pro-Kleen Concentrate patio cleaner can be used to clean all outdoor hard surfaces and removes moss, algae, mould and mildew. Simply spray and leave and you’ll start noticing results in a couple of days. In addition, this product offers lasting performance and will keep your patio looking like new for up to six months. It is also biodegradable, devoid of harsh chemicals, and doesn’t have a shelf life. It is safe to use around pets and kids too.

All things considered, is Pro-Kleen patio cleaner the best choice for you? Or, do you prefer the other cleaning products featured on our list?
