Petroleum jelly plastics and minimize ventilation issues, isopropyl (rubbing) alcohol can be used to remove petroleum jelly from most surfaces. Isopropyl alcohol is inert to most household surfaces, including almost every plastic, and removes petroleum jelly efficiently. While alcohol causes fewer ventilation problems than petroleum solvents, ventilation is still recommended, especially if large surface areas are involved. Petroleum jelly is also soluble in lower-molecular-weight oils. Using an oil to dissolve the petroleum jelly first can render it more soluble to solvents and soaps that would not dissolve pure petroleum jelly. Vegetable oils such as canola and olive oil are commonly used to
