Patios frequently gather dirt, but moss, particularly, is exceptionally persistent and has a tendency to proliferate rapidly, dominating the space. Moss can attach itself to porous surfaces such as stone, brick, or concrete and penetrate minuscule gaps, rendering it difficult to eliminate despite intensive scrubbing.
Lenard Nagy from Perfect Clean Cleaning Services explained: “Moss growth on surfaces is a common problem that can make your concrete look dirty, dull, and unattractive. It can also damage your concrete over time by creating cracks and holes and pose a safety hazard by making your concrete slippery and causing falls and injuries.” Thankfully, according to Lenard, there’s an incredibly straightforward and powerful technique to eradicate this green pest without requiring harsh chemicals or specialist equipment.
It appears that baking soda is amongst the most successful approaches for removing moss from stone surfaces and stopping its reappearance.
Baking soda functions by swiftly dehydrating and destroying the moss, and, given that moss flourishes in acidic conditions, baking soda’s elevated alkalinity modifies the pH of the stone surface, establishing an environment that is unwelcoming for moss development.
Lenard Nagy said: “Baking soda is a common household item that you can use to clean moss from concrete.
“Baking soda is a base that can raise the pH of the moss and kill it…[and it] is also gentle and safe for your concrete and the environment.”
To eliminate moss from your patio, begin by liberally spreading baking soda across the affected sections, making certain the moss is completely covered.
Take care to keep the baking soda away from any plants or grass, as it can dehydrate and damage organic matter. Whilst a modest quantity of baking soda is unlikely to harm your garden, it’s advisable to avoid using this technique on blustery or wet days to prevent the baking soda from dispersing accidentally.
Following application of the baking soda, allow it to remain for 24 hours. Throughout this period, it will infiltrate the moss and cause it to turn brown as it dehydrates.
Once the waiting time has elapsed, the moss should be entirely dried. Use a broom or rigid brush to sweep away the dead moss from the patio.
Lastly, rinse the patio by hosing it down or pouring a bucket of soapy water over it to wash away any lingering baking soda and dead moss. Your patio will be left spotless and moss-free.
