What is Penetrating Oil?
It is a form of low density or viscosity fluid which has the properties to attack the rust that corrodes and eats away most of our tools, equipment and other mechanical parts. Rusting can often affect the functionality of the machine and eventually rendering it useless.
However, that problem can be solved with the use of the right type of penetrating oil that is suitable for the situation and the type environment that mechanical parts are. Which is why it is important to know the properties and complete information of any penetrating lubricant before you buy it.
A few thing to keep in mind when buying penetrating oils:
- The Main Purpose: It is always helpful to know exactly the type of machinery and the sort of bolt, screws and metals that you deal with on a daily basis.
- The Properties: Always read up on the properties when you buy; You should know how it reacts with rubber or plastics or if it can withstand high temperatures. It is important to have all information so you can buy the penetrating lubricant that is suitable to the criteria that you work in.
- Convenience: The type of the container the lubricant comes in is vital. If you have never used a penetrating oil spray before, you need one that is easy to use and handle, preferably a lubricant with a straw so you don’t encounter any accidents.
- Fluidity: The fluidity, or the viscosity matters because different circumstances call for different types of penetrating oils. The viscosity needed depends a lot on the the purpose of your need ie. if you need to lubricate hinges or bolts in tight spaces or just clean up your tools. For Example Kano Aerokroil Penetrating Oil is the best oil for seized bolts because of the fluidity.
- Price: Although mentioning the price seems futile but you have to know the average price of the such in the market so you don’t go overboard with it. Remember, expensive doesn’t always mean that it is the best penetrating oil or if it is even worth it.
