Buy this product if your car’s A/C smells raunchy! Ever notice an odd smell of socks, urine, booty, or mold when you first turn on your A/C? The odor lasts no more than 30 seconds but it greets you each and every time you turn on your A/C. Not only that, it’s awfully embarrasing when you get into the car with a passenger. The odor is caused by mold and bacteria growing on and around your evaporator. Changing your car’s filter will NOT make the smell go away. You must kill whatever is growing and that is what this product does. It works well and you only need to use it once or twice a year. The can comes with a two-foot long plastic tube (I don’t know why they don’t show it in the photo) that’s used to apply the anti-bacterial foam directly to the stuff growing in your evap. Don’t let the car dealer rip you off. This spray will help you solve the problem yourself, for cheap.
