Forklift lost his grip since it got sprayed with WD-40

Hello my father and I repair forklift and work on hydraulic work while we work we keep the WD-40 on us at all time when working with hydraulic cylinder , you must remove pings to access them since they keep them secure and tight . WD-40 gets sprayed on these rusted beat, old equipment and penetrates through the debris and makes it loose and and be free . Wd-40 is a must while working in anything it’s such an essential thing to require which is we we always recommend the best which is WD-40
