On the hunt for the best patio cleaner? Of course you are – it's that time of year and the sunny weather's perfect for the job. And, after all, you've gone to the trouble of designing the perfect patio, now you'll want to keep it looking as good as new. 

However high-quality your paving, over time, damp weather conditions encourage the growth of algae, creating a green coat on your patio. Moss, lichen, and mould can also become a problem, making your patio unkempt – plus, it'll be slippery. The best patio cleaners will tackle all of these issues – and some of them will even help you get rid of weeds that may be growing, too.

Patio cleaners or pressure washers to remove algae and unwanted plant growth? They're equally effective, but patio cleaners are cheaper to buy and use; they may not offer instant results, but when the formula's worked (sometimes it can take up to a couple of days), your patio should be good as new. 

Worried about eco-friendliness? Most patio cleaners are biodegradable, which means they shouldn’t cause any long-term damage to the environment.
