The Many Benefits of Penetrating Spray & Aerosol

Are you working on heavy equipment, a vessel, truck or earth mover that has metal parts that have rusted or seized up? It can often be difficult to get those stuck parts to move at all. Sometimes, you find that a bolt, a screw, or another fastener has become so rusted that it has merged with the parts surrounding it. One of the best ways to make short work of those rusted or seized parts is by using an aerosol penetrating oil.

Trying to get some of those parts loosened can be difficult even when they aren’t rusted. Trying to drip penetrating oil onto those areas can sometimes be difficult, so opting for a spray rather than liquid could be a good choice. It can make it easier to reach difficult areas and to cover the entire surface.

The Benefits of Using an Aerosol Penetrating Oil

Naturally, the main benefit of using this type of spray is to loosen items that are seemingly frozen together. Dealing with rusted or seized parts can slow down your work, which is the last thing you need. The spray can work easily on all sorts of metal parts. Whether you are working on a vehicle, air conditioning unit, tractor or any other items that have become rusted or seized up, this spray could be the best solution.

It works quickly, and it is simple to apply. The aerosol spray can let you quickly and easily spray the rusted area. Once you let it seep into the threads, crevices, beneath washers, etc., it begins to lubricate and loosen the buildup of rust, allowing the pieces to be moved and taken apart. The spray cans are easy to store in your garage, tool cage or crib, for when you need them.

You will find that the aerosol penetrating oil can work just about everywhere. The aerosol tends to be easy to control, so it will spray where you need it. However, if you are working on tiny pieces, want to soak parts or you need to be accurate when applying the penetrant, you might want to choose to use liquid that lets you just drip it onto the area you need. You will find that Kroil offers several application options, not just a spray. Use the one that’s best for you.

Using the penetrating spray or liquid will also ensure that the rust is removed from the metal elements. It can loosen and remove rust from the pieces and because of the chemical makeup of the penetrating oil, it will help to prevent further corrosion by keeping moisture away. It may not take away all the rust from the pieces, of course, but it can help to remove some of it. Later in the article, we will talk about some of the other ways that rust can be removed from the metal.

Penetrating spray or liquid could also be used to help with cleaning more than just the rust from metal. It could also work well to remove gum and adhesive that are on the metal. They are a solvent that can break down these materials, including grease. Of course, you do need to be careful when using it, since there may be areas that require grease to function properly.

You will be happy to know that the penetrating oil can penetrate quickly, and it can reach deep. It will make its way into the threads, beneath washers, and into other areas that would be difficult to reach. Once it works its way into those areas, it can be worked and loosened. It will remove the carbon and rust deposits, but it won’t harm the metal beneath.

The penetrating oil also has a lubricating effect. If you need longer lubrication, you can opt for Kroil Penetrant with Silicone. This can provide long-lasting lubrication, which makes it a good option for the next benefit we have—noise reduction.

When you use the spray on rusted chains, pulleys, fans or track pins, it can reduce squeaks and other noise that you might hear otherwise. While this might seem like a small benefit, it is a nice quality of life improvement that you will notice and appreciate.

Types of Penetrating Spray

You can find several types of aerosol penetrating oils  in the market today. When you are making your choice, you will want to make sure that you understand what type you are choosing. With Kroil, you have two options. You can choose Kroil Original Penetrant, or you can choose Kroil Penetrant with Silicone.

Which one will be right for you? It will depend on how and where you are using it. Do you need to have the added lubricating benefits or not? If you only need the penetrating oil to help remove some stubborn bolts, then you probably don’t need the added silicone. However, if you are working on a part that would benefit from lubrication, it might be a good idea.

Many people will have multiple reasons to use penetrating spray and may find that having some of each type of spray could provide the biggest benefit. Just make sure that you keep them separate and are aware of which one you are using when you grab it off the shelf.

Best Penetrant

Naturally, you want to be sure that you have the best penetrant for your projects. Therefore, you want to choose items that have a good record in the field and that have been proven to be useful. Kroil has been in business for more than 80 years and has developed formulas that work extremely well.

You will find that there are multiple options available when it comes to the type of spray—original and with silicone—and there are multiple size options. For the Kroil Original Penetrant, you can opt for an 8oz or 1 gallon liquid or 10oz, 13oz and 16.5oz aerosol. For Kroil Penetrant with Silicone, there are 10oz and 16.5oz aerosols.

When you are buying, you should also think about how much of the product you will need. Is one can enough or do you use it daily? If you are running a manufacturing or an industrial facility, then you might find that you need to have quite a few more cans of the penetrant spray on hand, so you do not run out.

Always make sure you are using high-quality penetrating oil whether it’s a small, simple project that you only need to use once, or if you work with the penetrant daily. It will provide better results and will make your work much easier.

Using the Penetrating Spray

Before you start using the penetrating spray, it’s important that you know how to use it properly. You might want to test the spray in a safe location, so you can see how the aerosol comes out of the can. This will give you a better idea of how to use the spray when you are using it on the various metal surfaces that require it.

One of the main questions that people ask when they are using these types of sprays is how long they take to work when trying to loosen items. The answer is that it will vary. In many cases, particularly when the rust is not too bad, it can start working in about 15 minutes or so. This means you can get back to work relatively quickly after applying the spray. In other cases, it could take quite a bit longer. It might take several hours, or overnight and may need additional applications. It all depends on the state of the material on which you are using it and the quality of the penetrating oil.
