On the hunt for the best patio cleaner? Let's face it: anyone with a patio will be spending a lot of time out on it in the coming months – even more reason than usual to get your patio pristine and algae-free. With the exceptionally wet winter we've had, many of us will find our patios overgrown with algae and moss that love excess moisture.

Help is at hand, though, with a huge selection of patio cleaning products that promise to leave your patio looking like new. 

Patio cleaners or pressure washers to remove algae and unwanted plant growth? We say both, and start with the patio cleaner. Choose a dry spell and leave it on for a good couple of days. Then, pressure wash away. 

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