Works great but keep pets off until dry. Definitely wear gloves as can be detrimental to skin. I used watering can with sprinkler for large decking under trees so didn’t need to jet wash off. **Q: Is this “patio cleaner” or “green moss and algae remover “ the pictures show 2 different products. are they the same product?** A: Hi, I've found it does all, cleans the stone kills the moss and algae on patios and walls which is great. Very happy with it, i make the mix a bit stronger than recommended as it lasts longer and is more effective. **Q: Can the ground be used for plants after spraying the moss** A: This product is for use on hard surfaces such as paving, concrete and stone etc. It is definitely not for use on soil. The product description confirms this fact. You will need to look for other products that are specifically for gardens. I suggest that you refer to a garden centre for advice. Most moss on soil is generally a combination of too few nutrients, not enough light and continual damp and this is not appropriate for your intended use. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highly Effective *by R***N on 2 May 2026* There’s a lot of these types of products out there, but I keep buying this one because it’s so effective at getting rid of algae from our driveway, fence panels and patio.
