WD-40 for Arthritis Pain

Tabloid headlines and Internet rumors claim WD-40, the popular spray lubricant and metal cleaner, can be used to treat arthritis. Unfortunately, those claims are not only false, but the use of WD-40 for arthritis can prove dangerous.

  1. Fact

    • WD-40 contains petroleum distillates, the same harmful chemicals found in gasoline and oil.

    Myth

    • The myth claims spraying WD-40 on aching joints will ease arthritis pain the same way it fixes a squeaky hinge.

    Warning

    • The petroleum distillates in WD-40 can cause skin rash and allergic reactions. Prolonged exposure can lead to increased cancer risk and other serious illnesses. Breathing the vapor may damage the delicate linings of the mouth, nose, throat and lungs.

    Considerations

    • People finding relief from arthritis after using WD-40 are likely experiencing a placebo effect. Massaging the WD-40 into the aching joint may also increase blood flow to the area, tricking the user into believing the arthritis pain is lessening.

    Expert Insight

    • According to its official website, the company that makes WD-40 does not recommend the product's use for medical purposes and has no knowledge of it being effective in treating arthritis pain.
