can you take aerosols in checked baggage

Yes, aerosols can be taken in checked baggage, but there are specific rules to follow. According to TSA and FAA regulations, aerosols must not exceed 18 ounces (500 milliliters) per container, and the total quantity for all aerosols in checked baggage must not exceed 2 kilograms (70 ounces) or 2 liters. Additionally, permitted aerosol containers must have their release valves protected to prevent accidental discharge. However, some aerosols are prohibited due to flammability, such as spray paint, cooking spray, WD-40, and aerosol laundry products. It is also advised to check with the airline for any additional restrictions before packing aerosols in checked luggage.
