When it comes to fixing a squeaky door or a stuck nut, penetrating oil is your best friend. But what exactly is this oil, and does penetrating oil work?
In most cases, penetrating oil can effectively loosen a stuck part in just a few minutes. It’s also relatively inexpensive and easy to find at your local hardware store.
Read on to learn more about how penetrating oil works and how to use it effectively.
Does Penetrating Oil Work?
The short answer is: yes, penetrating oil does work. But it’s not a miracle solution and won’t work in every situation. Mainly, it helps to loosen the linkages when they are stuck. So you won’t have to apply extreme forces. The low viscosity of the oil helps to untangle the seized areas.
What Is It All About?
If you don’t already know, penetrating oil is a lubricant designed to penetrate tight spaces. It helps loosen stuck nuts, bolts, and other metal parts. It’s also effective at lubricating door hinges and other moving parts.
How Does Penetrating Oil Work?
Penetrating oil is most effective on small parts exposed to the air, like door hinges or nuts and bolts. The longer the oil penetrates, the better chance it has of working. The oil ensures the motion between the stuck parts. As it dissolves the rust and debris in the area, the lubrication makes it easier to remove the stuck parts.
Even for the deep-seated areas, the included solvent makes the oil thinner to be more penetrable. As the oil becomes thinner, it becomes more penetrable. Another thing is that the lubrication oil not only dissolved the debris, it also cleaned the rust to make the job easier.
The Function Of Penetrating Oils
Although we all know that the main work that the oil does is to loosen the stuck areas and fasteners, there is more to this. So if you want to make the most out of it, let’s look out for the functions!
- Lubricates The Best
Penetrating oils never fail to lubricate the surface, regardless of where you use them. It takes little time to soften the stuck region and make everything smoother. The nature of the oil is to reduce friction, providing you with the best lubrication.
- Prevents Corrosion
When you are worried about the corrosion inside the components, lubricating oil can save you from that. They can disperse water, which prevents corrosion build-up. When you need a strong corrosion barrier, nothing can beat the oil.
- Noise Reduction
In industrial environments, penetrating oil can work like magic to reduce the noise from the tools. The magic is in your hands whenever you are irritated by the deafening sound!
- Cleaning Control
Some penetrating oils work for cleaning the areas; those are very effective in removing grease, adhesive, tar, and rust. As the oil contains solvent, it softens the areas and removes the grease and dirt.
Does Penetrating Oil Work Everywhere?
Penetrating oil is most effective on small parts exposed to the air, like door hinges or nuts and bolts. The longer the oil penetrates, the better chance it has of working.
That’s why you might need to apply penetrating oil to a frozen door hinge and wait a few minutes (or even hours) before the door will open. But if you’re trying to loosen a stuck nut, let the oil sit overnight before it does its job.
Penetrating oil is also effective on non-mechanical objects. For example, you can use it to remove gum from your hair or carpet. You can even use it to remove a stuck ring from your finger.
Regarding mechanical parts, penetrating oil can loosen rusted or frozen nuts, bolts, and screws. It can also help dissolve rust that’s built up on metal surfaces.
Where To Use Penetrating Oil?
Penetrating oil penetrates metal surfaces and loosens rusted or frozen parts. The oil works by seeping into the small cracks and crevices on the metal surface, lubricating the metal, and helping to loosen the rust or frozen part.
Penetrating oil is often used on tools, machines, and other equipment exposed to moisture or humidity, which can cause rusting. The oil can also help loosen frozen parts, such as door hinges or nuts and bolts.
Usage To Loosen Metal Parts
Penetrating oil is typically applied to the surface with a brush or cloth and then left to sit for a few minutes before being wiped off. The oil will need to be reapplied periodically to maintain its effectiveness.
Remove the parts when you have a frozen or stuck part that requires lubrication to work again. Then pour or use a brush to apply the oil to the areas. Leave the oil for a while to unstick the parts. It can work for hinges, bearings, gate valves, slides, and other metal parts.
Again, if the issue is a stuck screw when you haven’t removed the screws for a while, you can also deal with that using the oil. Even if the screw has rust due to being stuck for a long time, the oil will get through it. In such cases, you can spray the oil in the areas to soak it; after 15 to 30 minutes, you can remove the screw without any damage.
Usage For Rubber Or Plastic Components
Like metal components, any issues with plastic or rubber components can also be dealt with using penetrating oil. PTFE or silicone containing penetrating oils makes the surface slippery while repelling water. Applying those in the areas can create good lubrication to remove the components swiftly.
Usage For Grinding And Coolant Intents
In this case, you need to be selective about choosing the oil. There are foaming or non-foaming formulations that you will get to choose from. Non-foaming oils work best when you want to use the oil for grinding or coolant needs.
For your convenience, here’s a short tip on when and when not to use the oil:
When to use penetrating oil:
- To loosen a frozen door hinge
- To remove a stuck ring
- To loosen a corroded battery terminal
- To loosen a seized nut or bolt
- To lubricate a door lock
When not to use penetrating oil:
- On an electrical connection
- On a moving joint
- On anything that will be exposed to high temperatures
How To Get The Most Out Of Penetrating Oil?
You must use it correctly to get the best results from penetrating oil. Here are a few tips:
- Choose the right oil: Not all penetrating oils are created equal. Some are more effective than others. Do your research and choose an oil known for penetrating and loosening rust.
- Give it time: Penetrating oil needs time to work. Don’t expect instant results. Let the oil soak into the parts for at least a few minutes (or hours, if necessary) before trying to loosen or remove them.
- Be patient: Penetrating oil won’t work miracles. It can’t magically fix everything. If something is severely rusted or frozen, penetrating oil might not be able to help.
- Use other tools: In some cases, you might need other tools, like a hammer or a chisel, to help loosen the parts. Penetrating oil can only do so much, which might not be enough to loosen a stuck part completely.
- Clean the parts: Once you’ve used penetrating oil to loosen them, clean them thoroughly. Otherwise, they might attract dirt and grime, which can cause them to become stuck again.
How Long Should You Leave Penetrating Oil?
The time you leave penetrating oil to work will depend on the severity of the corrosion or seizure. Sometimes, you may only need to wait a few minutes before attempting to remove the part. In other cases, you may need to let the oil penetrate overnight.
Letting the penetrating oil sit for one to two minutes for mechanical parts should be sufficient. If the part is still stuck after this time, you may need to increase the time you let the oil penetrate.
For severely corroded parts, you may need to let the oil penetrate for several hours before removing the part.
Can Penetrating Oils Be Used As Lubricants?
No, you cannot use penetrating oil solely as a lubricant. They may sometimes work, but you cannot rely on the oil for your permanent solution. Penetrants leave a thin layer of lubrication in the area.
As a result, it wears out quicker than a dedicated lubricant. Thus, for lubrication or corrosion resistance, you should choose something which contains special additives for dealing with that.
What Can I Use Instead of Penetrating Oil?
If you don’t have any penetrating oil, here are a few other products that can be used as substitutes:
While WD-40 isn’t technically a penetrating oil, it can be used to loosen stuck parts. Just spray WD-40 onto the stuck part and let it sit for a few minutes before attempting to remove it.
2. Soap and Water
If you have a stuck part made of metal, you can try using soap and water to loosen it. Just apply a generous amount of soap to the area and let it sit for a few minutes before attempting to remove the part.
Vinegar is another household item that can be used to loosen stuck parts. Just apply vinegar to the area and let it sit for a few minutes before attempting to remove the part.
4. Vegetable Oil With 5% Acetone
If you have a plastic stuck part, use vegetable oil with 5% acetone to loosen it. Just apply a generous amount of the mixture to the area and let it sit for a few minutes before attempting to remove the part.
As you can see, a few household items can be used as substitutes for penetrating oil. So, if you ever need to loosen a stuck part but don’t have any penetrating oil on hand, give one of these substitutes a try.
Ultimately, Is It Worth The Time?
Yes, we have loved how the penetrating oil has been serving us so far. It takes very little time to dissolve the rust. Also, lubrication helps whenever we need something to come out of place. So, as you know, it works well to get you out of trouble.
