This article does not give blanket approval for baking soda in every washing machine. The appliance manual, intended purpose and products used are what matter. Bosch advises against household remedies for machine cleaning and points to recommended cleaners.
Distinguish laundry, cleaning and descaling
A laundry additive, machine cleaner and descaler serve different purposes. Check what is intended for your model and its dispensing system. Without appropriate manufacturer guidance, do not use baking soda as a routine additive or replacement for a specified care product.
Check care first if there is an odour
- Dose detergent according to load, soiling and water hardness.
- Remove wet laundry promptly after the programme ends.
- Care for the drawer and seal, and use any cleaning programme, according to the appliance instructions.
- Do not make your own mixtures with other cleaners. Ask the appliance service team if odours or faults persist.
Common questions
Does food grade mean approval for a machine?
No. Suitability for food does not answer questions about material compatibility or the dispensing system.
Are more powder and a hotter programme always better?
No. Quantity and programme must suit the specific product and appliance. No universal baking-soda dose or temperature is therefore recommended.
