Identify the stain and material
A food spill, dye, oil mark and finish change may need different treatment. Check the carpet, upholstery or surface care label first. Blot fresh liquid rather than rubbing and avoid applying powder before confirming it can be removed safely.
Understand baking soda's limits
An abrasive powder may scratch polished finishes, dull coatings or remain trapped in carpet and upholstery fibres. It does not disinfect and cannot reverse bleaching, dye transfer or permanent damage. Do not assume a paste is suitable for wood, stone, leather or delicate fabrics.
Use only a compatible, tested method
If the maker permits baking soda for that material, follow its instructions, test a hidden area as directed and remove residue completely. Do not mix it with vinegar, bleach, ammonia or a commercial stain product. Stop if colour or texture changes.
When to seek specialist help
Large spills, unknown substances, valuable fabrics or stains that persist after a permitted first response may need a carpet or upholstery specialist. Share the material, stain, age and prior treatment; no method can guarantee removal.
