5. Can work as a lubricant for machinery
At first, we mentioned that Vaseline is an excellent skin moisturizer, but did you know that it can unfold its magic in fine machinery? Petroleum jelly can be used in a solid-state and as an oil to make certain mechanisms work better. It is great for watches, but also the machinery of some toys and even some appliances. Have you ever thought about fixing your dishwasher with Vaseline? Well, now you should consider it!
What is really surprising about using petroleum jelly in fine machinery is that it is stable and very resistant over time. While the general recommendation is to inspect watches oiled with petroleum jelly periodically, there are known cases of pendulum clocks that operated for decades without the need for additional petroleum jelly.
However, it should be noted that petroleum jelly tends to accumulate dust and other air impurities.
