根据 WiKi, WD40 的配方如下:
50% Stoddard solvent (i.e., mineral spirits: primarily hexane, somewhat similar to kerosene)
25% Liquefied petroleum gas (presumably as a propellant; carbon dioxide is now used instead to reduce WD-40's considerable flammability)
15+% Mineral oil (light lubricating oil)
10-% Inert ingredients
係有一般潤滑作用, 但喷後表面比較 "濕", 会吸著灰塵, 用矽油比較好奌。 這個矽油也是 WD40 產品。
