    I learned about Water Displacement test # 40 a while ago. I then started using it for it’s purpose: water displacement. If I clean a part, even with alcohol ( grocery store bought is 9% water), I’ll dry and then spray with wd-40 to ensure the surface is completely moisture free. Then I’ll add the actual lubricant.
