Putting baking soda in the washing machine: what Maytag and Whirlpool advise

Putting baking soda in the washing machine can be useful mainly for managing smells and as a support product when washing certain items. Manufacturers such as Maytag and Whirlpool generally consider it safe for most machines, but they advise checking your model’s manual and note that it should be added straight into the drum, not necessarily into the detergent drawer.

Why can baking soda help during washing?

Baking soda is a mildly alkaline compound that can help neutralise odours and support the overall wash process. Maytag mentions it as an option to help tackle the smell of sweat, smoke, and other lingering odours in clothing.

It may also help balance the water’s pH and, in some situations, lessen the impact of hard water on fabrics. That said, it does not replace detergent; instead, it can act as a laundry booster.

Where should you put baking soda in the washing machine?

This point matters. Guidance from Maytag and Whirlpool recommends adding baking soda directly into the drum with the laundry, rather than tipping it into the detergent dispenser. The reason given is practical: the powder can build up and may contribute to blocking the compartment.

The amount should not be treated as one fixed rule for every appliance. Maytag references using up to around half a cup for a load, but still recommends consulting the manual for your specific model before adding it. You should also check garment care labels, particularly for delicate fabrics.

Can baking soda be used to remove smells from clothes?

Yes. This is one of the clearest uses mentioned in the manufacturer guidance referenced. Baking soda can help neutralise odours from sweat, smoke, and other persistent smells.

For items that still smell after washing, Whirlpool also describes making a paste from baking soda and water as a targeted pre-treatment. The garment should then be washed afterwards according to the instructions on its care label.

Does it really clean the machine and extend its lifespan?

Care is needed with that claim. Baking soda may be used to help control odours in the machine itself, and manufacturers acknowledge that this can be helpful. However, that does not mean occasional use will fully clean every internal part or guarantee a longer lifespan for the appliance.

Washer maintenance involves other steps, such as cleaning the dispenser, looking after the door seal, and running the cleaning cycle recommended for your model. For that reason, baking soda can be a helper for odours and washing, but it should not replace the cleaning programme or any products recommended by the manufacturer. It is also worth avoiding mixing it with vinegar inside the machine, because the combination reduces the chemical effect of both, and vinegar may be unsuitable for certain washer components.
