Wait a minute – turns out this cheap household ingredient might just be the easiest way to clean outdoor furniture

Summer's well and truly upon us, and if you haven't cleaned your outdoor furniture yet, it's probably overdue a refresh. Unlike our indoor dining table or chairs, patio sets need a little extra care and attention. Not only are they exposed to the elements, becoming more dirty more quickly, but they're made of different materials, so knowing what to clean them with can be a challenge. Fortunately though, you probably already have something stocked in your kitchen that's perfect for the job: salt. 

Whether you've only just hauled your patio chairs out of the shed for the summer or you're yet to clean up properly after your 4th July barbecue, it's a good idea to give your modern outdoor furniture the refresh it deserves, and this household ingredient is all you need for the job. 

We asked a cleaning expert how to use salt as a cleaning formula and which materials it's safe to use it on (including those that aren't). Here's what she had to say.

When it comes to cleaning your outdoor furniture with salt, it's not quite as easy as waving your salt shaker over your table and chairs as you would your plate of fries. That said, it's still pretty simple, and just as quick (almost). 

'The easiest way to clean furniture with salt is to mix it with water or lemon juice to create a paste,' says Prerna Jain, a professional cleaner and founder of Ministry Of Cleaning. 'Apply the paste to a sponge or cloth and gently scrub the furniture surface. The salt acts as a natural abrasive, helping to remove stubborn stains and dirt.'

According to Prerna, salt can also be used to help remove rust from metal furniture in your backyard. For this, she suggests a mixture of salt and lemon juice or vinegar to form a paste. 'Apply the paste to the rusted areas and let it sit for a few hours, then scrub the rusted areas with a brush or sponge,' she says. 'The salt's abrasive nature, combined with the acidic properties of lemon juice or vinegar, helps dissolve and remove the rust.'

For an extra cleaning boost, you can also leave salt-coated furniture in direct sunlight for a few hours. 'The combination of salt and sunlight can help break down stains and enhance the cleaning process,' adds Prerna.

If you've been keeping up with outdoor furniture trends, it's likely you've incorporated some plush cushioning into your backyard seating. If your patio furniture is upholstered with outdoor cushions, these can usually be removed and washed as normal in your washing machine. If you're looking for a quicker fix, however, salt has you covered. 

'You can sprinkle salt on upholstery or cushions, leave it for a few hours, and then vacuum it off,' suggests Prerna. Besides being quicker and saving money on the cost of running your washing machine, another advantage of this is that the salt has natural deodorizing properties. As Prerna explains, 'the salt will absorb odors, leaving your outdoor furniture smelling fresh'. It will also prevent the growth of mold and mildew on your outdoor furniture cushions, too.

What materials should you avoid cleaning with salt?

As a natural ingredient, salt is generally safe to use as a cleaning agent on most outdoor furniture, but when used as a liquid solution there are a few materials it's worth steering clear of. 

'It's best to avoid using salt on aluminum furniture, as it can cause pitting or corrosion,' explains Prerna. 'Similarly, be cautious when using salt on delicate materials like natural wicker or rattan as excessive scrubbing or salt residue can cause damage.' Wooden furniture could also become discolored if you use a salt solution on it regularly, so stick to a damp cloth and a mild soapy solution instead.
