The arrival of sunshine in the UK is casting a spotlight on grimy patios and paths, the remnants of a long, dreary winter. As thoughts turn to barbecues, outdoor dinner parties, or simply lounging in the garden with a good book, the sight of a green-tinged patio can be a mood dampener.
Fortunately, experts have revealed a 55p trick to eliminate the grime entirely. But what causes this green discolouration? Most stone patios are porous, retaining small amounts of water. When they become waterlogged, algae can form, giving your patio a swamp-like green hue. This issue often arises after a lengthy winter, as the cold, damp days create perfect conditions for this water-loving plant. Covered patios are also susceptible, as algae flourish in shaded areas.
Besides being an eyesore, an overgrowth of algae can pose a significant safety hazard due to its slippery nature, increasing the risk of falls.
To add insult to injury, decomposing algae blooms can let off a foul odour, similar to rotten eggs or vegetables, making your garden far from inviting. So, how can you swiftly get rid of it?
The answer lies in a simple solution. If you’re looking to tackle algae on your patio, experts have a straightforward and cost-effective solution likely available in your cleaning cupboard. The recommended approach is employing an equal mixture of bleach and water.
Bleach’s strong chemical properties make it good at eliminating bacterial growth.
Furniture Clinic warns that you should use this method carefully: “Care needs to be taken, as it can harm plants, grass and wildlife although you can spray greenery nearby with water before applying so that it dilutes any overspray.”
This tip is particularly welcome for the budget-conscious, as bleach is often a staple household item. For those who need to purchase it, bleach is affordable and easy to find.
For example, you can order a 750 ml bottle of Easy Citrus Bleach from Wilko at the low price of just 55p. Sainsbury’s also offers their Thick Bleach for a mere 70p, available in store.
However, if you find that algae is a persistent issue in your garden, be careful about using bleach regularly. Furniture Clinic advises against frequent use of bleach because of its harmful environmental impacts, stating: “Whilst it does kill the algae for now, it is not an eco-friendly option and the chlorine can sometimes change the colour and appearance of the surface.”
