FAQ

Is WD-40 a long-term lubricant? No, it's best for penetrating and freeing stuck parts short-term; follow with a dedicated grease for heavy-duty lubrication.

Can it harm paint or rubber? Safe on most surfaces with light use; test first and wipe excess to avoid buildup.

How do I store it safely? Keep upright in a ventilated area away from heat; shake well before each use for best results.
