What does vinegar do to remove gunpowder residue from skin?

Vinegar acts as a mild acid that can help break down the components of gunpowder residue, which often includes heavy metals and other chemicals. When applied to the skin, vinegar can help dissolve these residues, making them easier to wash away with soap and water. Additionally, its antibacterial properties can assist in cleaning the skin effectively. However, it's essential to follow up with proper washing to ensure all residues are removed.
