Patio Cleaner Buying Guide
It’s that time of year when we all want to spend more time in the garden enjoying the warmer weather. So of course, we want our outdoor spaces to look their best. The appearance of your garden can be spoilt by a dirty, algae-covered patio or deck. So, give yours a spruce up quickly and safely with a product designed especially for cleaning patios, decks and other hard surfaces.
The best patio cleaner products are effective at removing dirt, mould, lichen, moss and weeds, quickly and easily with no scrubbing or jet washing required. They improve the appearance of your patio, making it look like new, as well as making it less slippery and safer to use. Many patio cleaners also keep mould and weeds at bay for up to 12 months after the initial application.
I have used several patio cleaners over the years and the following are my recommendations for the most effective and easy to use. My personal favourite is Pro-Kleen, which is versatile, simple to use and keeps my patio and other hard surfaces looking great all summer.
Choosing a patio cleaner
The best patio cleaner solutions are better for your outdoor surfaces than scrubbing or using a pressure washer. These products do not damage the surfaces or affect the colour so are better for the finish of your patio and other hard surfaces than blasting with a jet wash or scrubbing. This is particularly important in areas that are grouted or pointed as the grout can easily be dislodged by vigorous scrubbing or jet washing.
When choosing the best patio cleaner for you, also look for products that are safe for the environment and not harmful to children, pets and wildlife.
So which patio cleaner is the best? Products that do not need rinsing will save you time, but they also continue to work over the following weeks and months and even up to a year, reducing the amount of work and keeping your patio looking good for longer.
Check the dilution required on the bottle as some smaller bottles may be more cost effective than larger bottles if they are more concentrated.
You may want to consider investing in a low pressure sprayer to apply the patio cleaner as this is the most effective and least wasteful method of application.
How to properly clean a patio?
If you want your patio looking its very best, some maintenance is required. Routine brushing will keep it free of falling leaves and debris, but removing stubborn dirt will require the use of a patio cleaner.
Moss, algae, lichen (black spot) and other fungi can thrive in damp conditions and can be tricky to remove. Knowing how to properly clean your patio is essential.
Pressure washers are a popular way to clean a patio, especially if it’s only recently been laid. To clean your patio with a pressure water you’ll need a heavy duty broom, power washer and water source.
Make sure your patio is swept and clear, and always start with a low setting. Increase the pressure gradually and remember that while very high pressure might be the most effective, it can damage the surface of your patio. Work from a shallow angle and from a good distance to prevent putting exerting too much pressure on your patio slabs.
To clean your patio using a chemical cleaner, ensure your patio is clear and swept. Remove any plants or furniture. Create your cleaning mix (many solutions will need diluting), and then use a watering can to distribute the cleaner evenly all over your patio. Leave to soak according to the manufacturer’s instructions, and then clean the area with cold water.
How to use a patio cleaner?
Apply your patio cleaner on an overcast day when rain is not expected.
Check the directions on your patio cleaner to see if it needs diluting and what ratio of water to add.
Although these products are safe to use, it is advisable to remove children and pets from the area until the product is dry.
Apply your patio cleaner with a low-pressure spray if possible. Alternatively, you can use a bucket and broom, or watering can.
Leave the product to get to work. Bear in mind that the active ingredients in patio cleaners can take a few days to work. On very badly affected patios it may even take a few weeks before all the stains are completely removed.
Use a patio cleaner regularly on hard surfaces to remove mould and algae as these can make your paths and patios slippery and unsafe.
