This oil is highly refined and has a very high flash point, well above 100 degrees Fahrenheit, which classifies it as combustible rather than flammable in its pure, stable state. Its low viscosity and quick-evaporating nature mean it leaves minimal residue, but this does not equate to being a fire hazard under normal use conditions.

Lubrication Myths Another reason the flammability question persists is a common misunderstanding about what WD-40 is designed to do. Historically, many aerosol products used highly flammable hydrocarbons like butane or propane as propellants.
Understanding the Core Question: Is WD-40 Flammable? To determine if WD-40 is flammable, one must first define what flammability means. Use WD-40 only in well-ventilated areas to avoid the buildup of fumes.
