Patios can deteriorate rapidly during summer and are particularly susceptible to moss and algae, which can be stubborn to remove. While these organisms thrive in colder months, Britain's humid summers cause them to cling tenaciously to outdoor surfaces.
Why Baking Soda Works
Experts at Infinite Paving have revealed a straightforward method to eliminate both moss and algae and prevent their return using baking soda. They said: "One very unconventional yet very effective way of getting rid of unwanted paving weeds is by using bicarbonate of soda."
Baking soda is an alkaline product that raises the pH level of a surface, making it inhospitable for moss and algae, which only survive in acidic conditions. It is also naturally absorbent, drawing moisture away from the patio and drying out the organisms.
Step-by-Step Method
Wait for a dry, sunny day and thoroughly sweep the patio to loosen any staining. Then, scatter a generous quantity of dry baking soda over areas affected by moss or algae. Leave it undisturbed for 24 to 48 hours to dry out the growth and raise the pH. Further applications can be made if desired.
You will know it has worked when the moss or algae turns brown, a clear sign it is dying. Once completely dried out, sweep the debris away with a broom and rinse with hot water. This leaves the patio looking clean and free from staining for a considerably longer period.
