As warmer weather sets in earlier than expected across the UK, many are beginning to prepare their gardens for spring and summer. But after months of damp, dark storage, garden furniture is emerging covered in grime, mildew and unsightly marks that can make even the cosiest patio set look tired and neglected.

But, an expert has revealed a simple, low-cost trick that could breathe new life into your outdoor setup in minutes, and it involves a common household cleaner found in many kitchen cupboards. According to interior designer Chris Catarino from WoodburyFurniture.com.au, sugar soap, which is typically used to prep walls for painting, is a surprisingly effective solution for tackling mould and dirt on wooden, plastic and even metal furniture. 

“You really don’t need to overthink it,” Catarino explained. “When it comes to surface grime or even mould buildup, sugar soap and a basic kitchen sponge are more than enough to get the job done.”

Costing between £3 and £5 a bottle, sugar soap can be used to break down layers of stubborn grime without damaging painted or sealed surfaces. 

Catarino recommends diluting the solution according to label instructions and wiping it over furniture using a soft, non-abrasive sponge or cloth.

For areas with stubborn mould or heavy buildup, allowing the cleaner to sit for a couple of minutes before gently scrubbing can significantly boost results. 

Once cleaned, the furniture should be rinsed thoroughly with water and dried completely before use.

While sugar soap is safe for most garden furniture types, including painted timber, plastic, and powder-coated metals, there are some materials it should be avoided on.

Catarino advised against using it on oiled or untreated teak, as the cleaner can strip the wood’s natural oils.

It’s also unsuitable for natural wicker or cane, which may weaken when exposed to moisture. Outdoor fabrics and cushions should also be cleaned with gentler detergents, as sugar soap can stain or affect water-repellent coatings.

Finally, furniture made from rust-prone metals with chipped or worn paint may be at risk of further damage if the cleaning exposes bare metal.
