A popular myth has grown around the use of WD-40 as a joint lubricant and pain reliever for arthritis. The liquid is sprayed on the painful joint much as one would fix a squeaky mechanical hinge.
Have you tried to use Wd40?Yes its an oil, but it gets a lot of things out. Alternatively try to mix baking soda and white vinegar. You can add lemon juice as well. Then use a â¦ light toothbrush or other method to apply the paste to the affected area.
