A sparkly clean, weed-free patio is quite the satisfying sight, particularly in the warmer months when garden parties and BBQs are in full flow. While natural garden growths such as algae, moss and lichens are unharmful, encourage biodiversity and often add a charming, Secret Garden vibe, they can cause slippery and untidy looking patios. Luckily, there's a range of patio cleaner solutions available, so keeping your decking and stone paving in tiptop condition is not too tricky or laborious a task.


You can opt for a specialised solution that's designed for specific surfaces such as stone, or wood. There are also multi-purpose solutions available if you'd rather clean your greenhouse, stone slabs and garden wall all at once.

It's worth thinking about the patio cleaner's eco credentials, and whether they're safe to use around little ones and furry friends! In our roundup, you'll find a range of organic and child/pet friendly options, so you can crack on with the job, whatever your household setup.
