Sahara dust discolours the sky
Garden experts are urging people to think about their outdoor furniture this weekend, as ‘blood rain’ is forecast across the UK.
According to reports, we can expect to see remnants of Saharan dust in our rain over the weekend, which can leave rust-like, reddish marks on outdoor furniture. Magdalena Gierasinska, Head of Product and Displays at Barker and Stonehouse, warned garden furniture could be ruined beyond repair.
According to experts, the coarse dust in the rain, if left on furniture, can lead to scratches and surface damage, while the brown or red sand can lead to staining. It has also been linked to mould, mildew and damage to fabrics.
Saharan dust lands on surfaces and can be damaging
Dr Claire Ryder, Associate Professor in Mineral Dust Processes at the University of Reading, told MailOnline: “As rain falls through air thick with Saharan dust, it picks up tiny particles of reddish–brown sand, leaving rusty orange smears on cars, windows and garden furniture. If your car looks like it’s been lightly coated in mud after a shower this week, this is why.”
The Met Office said: “There is no need for concern from a health perspective for the levels currently expected over the UK. Those with respiratory sensitivities may notice a slight increase in airborne particulates before rainfall clears the atmosphere, but concentrations should remain well below levels associated with air‑quality alerts.”
But Lena warned while there is little risk to health – there is risk to your garden furniture, adding: “The most common mistake I see people doing is leaving garden furniture exposed to the elements for long periods without any protection. Even the most weather-resistant pieces benefit from a good quality cover.
“Wooden and metal furniture are particularly vulnerable during wet and windy conditions. Corrosion-resistant paints may offer extra protection against salt exposure, but not against rust. As with all outdoor pieces, we recommend covering or storing aluminium furniture during harsh weather, and always removing the cushions first before you do.
You need to clean in a specific way
“If you have a garage, shed, or covered area, move your furniture indoors in advance of the storm. This is the most effective way to prevent water damage, rust, and wind-related stress on joints and frames.”
If storage space is limited, Lena says to invest in high-quality outdoor furniture covers that are both waterproof and wind-resistant to use during extreme weather conditions. “Ensure they fit snugly and are securely fastened to prevent them from lifting or tearing in gusty conditions.”, she warns.
Even with the best care, garden furniture will eventually reach the end of its life.
Lena said: “If you notice soft or spongy spots in wood, flaking rust on metal, or instability when using the furniture, it may be time to upgrade. Replacing compromised pieces ensures your outdoor space remains both stylish and safe for use.”
How to Protect and Clean Furniture:
Rinse, Don’t Rub: Use a garden hose or a pressure washer to rinse off the dust. Direct the spray in a downward motion to wash away the mud, rather than rubbing it.Use Soap and Water: For stubborn stains on fabrics or plastic, use a soft brush with warm water and mild soap.Cover Furniture: Use breathable, waterproof covers to protect your furniture when a Saharan dust event is forecast.Avoid Dry Cleaning: Never attempt to wipe the dry dust off with your hand or a dry cloth, as this will cause scratches.
