But don't get baking soda on carpet or upholstery.
It bleaches the fabric/carpet. Found this out the hard way after a backed up storm sewer flooded my street and filled my old Daysun 210 up to the bottom of the windshield with yucky water. The Baking Soda helped the smell but I had put it directly on the carpet hoping the carpet would smell better. It did, but when I vacuumed it up, the carpet was white under the powder.
