Patio Cleaner Buying Guide

A Sunday afternoon relaxing on your lawn with your family while the kids play on the trampoline and the adults sit on an inflatable hot tub is bliss. But it can be a nightmare if the patio is infested with moulds, algae, and dirt, or ants have taken over the grass in your lawn.

An ant killer will effectively remove the ants while a pressure washer can clean the patio. However, a patio cleaner will resolve a variety of issues at a go. You can simply use it with a garden hose to kill moulds and algae and remove dirt and stains from the patio. But you need the right brand to achieve the best results and we will show you how to get it.

How Infested is My Patio?

Before selecting a product, ask yourself if it will be efficient enough in both quality and volume. The higher the infestation, the more solution you might have to apply. In most cases, getting a highly concentrated patio cleaner might be the solution you need. If the level of patio stain is very intense, go for a product that is specially designed for heavily contaminated patios and paths. Concentrates tend to produce excellent results as they can be diluted and still won’t lose effectiveness.

How Powerful is this Cleaner?

Some are far more effective than others. The strength of a patio cleaner determines how well it will clean up the surface of your patio. While most patio cleaners are potent, some of the best focus on a specific group of patio grime. Most black mould algae patio cleaners are exclusive, therefore very effective in treating such. Other best patio cleaners are majorly efficient at achieving lichen removal from the patio. If you’re focusing on one or two types of infestation, select a product specially formulated for that purpose. Not all ‘All-purpose’ patio cleaners are truly all-purpose, so it’s usually best to purchase a product that will tackle the significant problem head-on.

How Does It Work?

Patio cleaners work in different formats and whichever you pick depends on certain factors. If you’re looking for a solution that would require minimal effort, you should purchase a ‘Spray and Leave’ product. These best patio cleaners only require you to apply to the affected areas and leave for a stipulated time. While some promise results in under hours, others might take days, but eventually, you wouldn’t have to do anything yourself. Other types might require minor scrubbing to agitate the result, so go for those if that won’t be a trouble. Also, some still require a little more work- light rinsing or sometimes, a jet wash. You should choose based on how much time and effort you know you can afford to invest in treating the patio.

What Kind of Surface am I Treating?

This might be perhaps the most crucial factor to consider before buying a patio cleaner. Generally, the best patio cleaners are designed to work most efficiently on specific surfaces. There are patio cleaners for concrete, limestone, wood, block paving, tarmac and many others. 

You need to put the kind of material the surface is made of into consideration before you buy a cleaner. This is because the composition of cleaners specifically designed for concrete might damage a sandstone surface.

Moreover, a block surface might not be efficiently treated if the cleaners employed are fashioned, especially for wood or glass. 

Patio Cleaner Buying Guide

Also, there might be some chemicals in the cleaner that might react negatively with the surface applied to. Patio cleaners containing bleach would damage wooden patio surfaces, and sodium hydroxide can be unsafe for uncoated surfaces.

How Much Space am I Working On?

If you’ve set out to get the ultimate cleaning fluid, ask yourself if the bottle you’ve purchased will cover your entire patio space. The density in the solution of patio cleaners vary greatly, and this determines how much of the material you have to work with. The denser the cleaning solution, the smaller the area you can use it on. Also, many best patio cleaners are concentrated and as such, can be diluted. Be sure to check the instructions manual if you’re buying such and stick to the recommended mix ratio for good results. If your patio is large, go for heavy concentrates. When diluted as per instructions are given, they give more volume of solution for broader coverage.

Is it Eco-and Pet-Friendly?

Just as you consider the power, potency and surface of the patio before buying a cleaner, also consider environmental safety. Patios are exposed to the outdoors, except for indoor patios. As such, they are exposed to nature as animals, and even pets come in constant contact with them. Fortunately, most best patio cleaners are made with pet-friendly materials, but it doesn’t hurt to double-check. Environmentally friendly patio cleaner usually advise that you wait a stipulated time before letting your pets and even your kids on the patio. They’re also entirely biodegradable.

How much can I spare?

You also have a factor cost when purchasing a patio cleaner. While many are quite pricey, this does not in any way indicate their level of potency. Make sure you analyze the features carefully, deciding if each one checks off on your list before paying for it. Also, if you’re working on a budget, go for a patio cleaner that offers most of the features you desire at the price range you can afford.

Understanding the Jargons.

This review does not make use of any jargon or unfamiliar abbreviation.

What are the different features?

Many features on most patio cleaners are considered very handy, but only a few attract general appeal. One of these is the versatility of the cleaner.

While many users seek the best patio cleanser the market has to offer, must keep in mind how much they can do with it. 

Patio cleansers that offer effective control over virtually all sorts of patio discolouration and infestation tend to get a second glance from customers and even recommendations when they deliver. This also comes in handy when the cleaner can be used effectively on a broad range of surfaces.

Features of Patio Cleaner

Another handy feature is environmental and pet-friendliness. Most users enjoy not having to worry about polluting their surroundings or poisoning their pets and kids. As most patio cleaners promise this, it gives the product a retail advantage.
