Vinegar is a gentle, natural cleaning product that can be used for many different purposes. Using vinegar on a carpet spot usually is effective at removing the stain, but it also can leave a lingering, acidic odour. If you want to keep your carpet clean and smelling fresh, you can eliminate odours from vinegar by using another gentle household product--baking soda. Baking soda is inexpensive, and the odour removal process is quick and simple.
Blot the area affected by the vinegar if it is still damp. Use a clean, white cloth.
Sprinkle baking soda over the affected area of carpet and let it sit for about an hour.
Vacuum the carpet thoroughly.
Reapply more baking soda and vacuum again if necessary.
The passing of time also will help to eliminate vinegar odours. As the vinegar evaporates from the carpet, the smell will eventually fade as well.
