How to use baking soda to clean carpets and upholstery

Baking soda is a straightforward household helper for cleaning and deodorising items that collect odours, dust and light grease. On carpets, upholstery, mattresses and other household surfaces, it can absorb smells and loosen surface dirt, provided it is used correctly and fully removed after the recommended contact time.

Why does baking soda work on carpets and upholstery?

With its fine texture and deodorising properties, baking soda can help lessen odours caused by everyday use, slight dampness, perspiration, dust and residue built up in fabrics. It is not a replacement for deep cleaning, but it can make routine care between more thorough cleans far more effective.

In most situations, the key is to apply the product dry. Mixing it with too much water can create a paste that is difficult to remove, leave marks and even add unwanted moisture to thick fabrics.

Which 6 items can be cleaned with baking soda?

Baking soda is most effective on surfaces needing deodorising and light cleaning. Before using it, remove loose dust, crumbs and debris so that the product can work more efficiently.

• Carpets: sprinkle on a thin layer, leave it for 20 to 30 minutes, then vacuum thoroughly.
• Upholstery: use a small amount, distribute it with a soft brush and remove it using a vacuum cleaner.
• Mattresses: leave it in place for 30 minutes to 1 hour to reduce odours.
• Pet beds can be given a light application before washing or vacuuming.
• Dry trainers and shoes can be deodorised with a small amount placed inside.
• Thick curtains can be treated with baking soda on targeted areas before vacuuming.

How can you apply baking soda without damaging materials?

Every surface requires care. Delicate, coloured, velvet or specially treated fabrics should be tested on a concealed area before treating the entire item.

• Use a small amount: a light layer is enough.
• Avoid over-wetting: trapped moisture may lead to stains and unpleasant smells.
• Do not scrub fragile fabrics harshly.
• Remove every trace with a vacuum cleaner or clean brush.
• Never combine baking soda with bleach, chlorine, ammonia or unknown products.

What is the ideal contact time?

For carpets and upholstery, 20 to 30 minutes is generally enough for standard maintenance. For mattresses, pet beds and items with more persistent odours, the time can extend to 1 hour, as long as the room is dry and well ventilated.

Once this time has passed, it is important to remove it carefully. Baking soda residue left in fabric can create white powder, bother people with allergies and make the surface look poorly finished.

When is baking soda not enough on its own?

Baking soda can help with odours and light dirt, but it does not fully remove deep stains, mould within the material, ingrained urine, old grease or dust mites. In these circumstances, the fabric may need washing, a specialist product or professional cleaning.

To keep the results for longer, vacuum carpets and upholstery regularly, air out rooms and avoid leaving fabrics damp for many hours. This makes baking soda an inexpensive, practical addition to the routine, without the risk of damaging materials through excessive use.
