Your Patio Cleaner Buying Guide


A patio infested with algae, mould and dirt can be a nightmare. But this frustration can get worse when you buy an ineffective product or one that is not strong enough. Our guide will help you to find the perfect cleaner for your home!

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.

How Does It Work?

If you’re looking for a solution that would require minimal effort, you should purchase a ‘Spray and Leave’ product. These 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.

What Kind of Surface am I Treating?

This might be perhaps the most crucial factor to consider before getting 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, decking, block paving, tarmac and many others.

How Much Space am I Working With?

The best patio cleaners are concentrated and can be diluted. If your patio is large, search for heavily concentrated products. When diluted, they can cover a couple of hundred square metres.

Is it Eco-and Pet-Friendly?

Fortunately, the best patio cleaners are made with pet-friendly materials, but it doesn’t hurt to double-check. Environmentally friendly patio cleaners usually advise that you wait a stipulated time before letting your pets and even your kids on the patio. They’re also entirely biodegradable.


FAQs


Q: How to clean patio paving slabs?

A: Simply use a stiff brush broom to agitate the moss and weed growth or apply a vegetation killer before cleaning the patio paving slab. The latter can take up to two weeks for full results.

Q: How to clean a patio without chemicals?

A: You can use vinegar to clean your patio. Mix in water or use neat and apply with a squirt bottle before scrubbing about 20 minutes after application. You can also spray it off with a power washer.
