How baking soda cleaning works

Baking soda is a super-effective but gentle abrasive cleaner and natural deodoriser. Although tons of us keep it in our cupboard to use as a leavening agent in cooking, it’s a form of salt that causes dirt and grease to dissolve in water, as well as being brilliant at absorbing odours. 

Bicarbonate of soda vs baking soda

Are baking soda and bicarbonate of soda the same thing? Yes, baking soda and bicarbonate of soda are the same thing. Baking soda is the American name for what in the UK and Australia is bicarbonate of soda. 

Can you mix baking soda with vinegar to clean?

In addition to tackling so many cleaning and freshening tasks both inside and outside your home, when it’s combined with white wine vinegar, the dynamic duo produce a fizzy chemical reaction that works wonders in the kitchen and bathroom.  (use our guide to cleaning your home with vinegar to find out more about that wonder product).   

How much baking soda do you need for cleaning?

That tiny tub of baking soda that you have on your kitchen shelf won’t last you very long once you start to reach for it everyday, so look online for a larger, money-saving quantity, such as Hexeal's 5kg bucket of bicarbonate of soda or Dri-Pak's 1kg bags of soda crystals specifically for cleaning purposes.

What can't you clean with baking soda?

Aluminium cookware will discolour if bicarbonate of soda is allowed to sit on its surface for too long, so if you do use it, rinse it off quickly.

Antique silver: despite the fact that baking soda is good for removing tarnish from silverware, some jewellers advise against using it on antique silver because it can be too abrasive on items that aren’t made from sterling silver. 

Jewellery: don’t use it on any jewellery decorated with inset jewels such as turquoise or pearls.

Gold-plated items: if you have any dinner services with a gold rim or gold accents, bear in mind that gold is a soft metal and is easily scratched – even with a light abrasive like bicarbonate of soda.

Marble surfaces: stone manufacturers don’t recommend using baking soda as a marble cleaner because repeated applications can cause the sealant to wear away.
