A landscaping expert has warned several popular patio cleaning hacks may cause more harm than good. With autumn just around the corner, many Brits are giving their green spaces a final clean and tidy up - bracing themselves for an onslaught of rain and freezing temperatures that will inevitably wreck havoc on our gardens. Giving your patios a good scrub is a great way to get rid of stubborn dirt, mildew, and moss that somehow flourishes in every nook and cranny - even during the summer months.

Searches for the term 'how to clean paving' skyrocketed a whopping 455 per cent earlier this year, while a slew of households experimented with different ways to keep their patio sparkling. But, there are certain products and chemicals that should be 'avoided completely' when it comes to paving stones. Andy McLaughlin at RF Paving has advised against using industrial substances in the hope that more potent products will yield better results.

"The pH of the cleaning substance may not be conducive to the type of paving being cleaned and may cause a chemical reaction and could leave marks on the surface of the paving, which can be irreversible, such as if brick acid was used on limestones," he added. The gardening ace also cautioned social media users raving about using cleaning products normally used inside the house. Holy grails like the Pink Stuff Cream Cleaner have been featured in a plethora of TikTok videos, with gardening enthusiasts sharing their 'incredible' transformations.
