What Does Ammonia Smell Like?

Ammonia has a very strong, pungent odor that is easily recognizable. It is often described as smelling like a strong household cleaner or bleach. Ammonia can be found in many different types of products including cleaning solutions, fertilizers, and even some automotive fluids. In most cases, it is the result of a chemical reaction between certain compounds present in the car’s engine.

Sources of Ammonia in a Car

The most common sources of ammonia in a car are coolant leaks, exhaust fumes, and oil buildup. Coolant leaks can cause an ammonia smell due to the chemical reaction between the liquid and air when it escapes from the cooling system. Similarly, exhaust fumes contain ammonia which can enter the car’s cabin through vents or other openings. Finally, oil buildup can also cause an ammonia smell as it breaks down into smaller particles and combines with air.

Reasons Why It May Smell Bad

In some cases, an ammonia smell coming from a car may be caused by something other than a chemical reaction. For example, if the cabin air filter is not changed regularly then dust and other contaminants can build up and cause an unpleasant smell similar to that of ammonia. Additionally, mold or mildew growth can also produce an odor similar to that of ammonia.

How to Clean Up a Car That Has an Ammonia Smell?
