No, you are supposed to mix the baking soda and vinegar to make a paste, and wipe the inside of the oven with it. I assume you pour the ammonia down the drain. Or clean something else with it. You would be better off mixing the baking soda with water to make a paste, as water will not neutralize any of it, as the vinegar will. I believe some people also wipe the oven with a cloth or paper towel soaked in vinegar, to neutralize the ammonia &/or baking soda. I don't really think that would be necessary. Just wipe it out with damp paper towels.
