Broke a quart jar in backseat floor and have vinegar in carpet. How best to neutralize it. Should I just flush and shampoo maybe. It is under the front seat mostly where it ran off the floor mat. Product was like Penrose sausages but venison and sliced hot pepper.

Baking soda will neutralize the acidity of vinegar.

Use warm water to disolve baking soda first...

Dissolved lime or wood ash will also work on a weak acid like vinegar.
