Starter spray, also known as starting fluid, is a flammable liquid used to help start internal combustion engines. It is typically used in cold weather or when an engine has been flooded with fuel.
Starter spray is typically made from a mixture of hydrocarbons, such as propane, butane, and pentane. It is also often mixed with a small amount of oil to help lubricate the engine. Starter spray is highly flammable, so it is important to use it with caution. The can should be held upright and away from the face, and the engine should be running before the spray is applied.
