Best patio cleaners for stone paving and decking

A sparkly clean 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 harmless, encourage biodiversity and often add a charming, Secret Garden vibe, they can cause slippery and untidy-looking surfaces.

Opt for a specialised solution for surfaces like stone or wood, or choose multi-purpose solutions if you'd rather clean your greenhouse, slabs and garden wall all at once.

It's also worth finding an eco-friendly cleaner, especially if little ones and furry friends are around! We've included a range of organic and child/pet friendly options, so you can crack on with the job whatever your household setup.

Wet & Forget, 5L

This is a versatile cleaner that works on tarmac, roofs, paths and paving as well as patios. It's designed to remove mould, lichen and algae, so you can keep your patio in pristine condition.

It works best with a sprayer, and as the name suggests, there's no need to rinse. While it's biodegradable and bleach-free, it's only safe for animals and children once dry, so you'll need a free garden.

This patio cleaner is specifically designed for cleaning stone. It removes dirt and offers weather protection, so it's an ideal choice if you're fed up of stormy winds and hail damaging your stone features. It also tackles fungi and algae.

You can use the same pressure washer for different Kärcher detergents, including car cleaner, so it could be a versatile and useful garden gadget.
