Penetrants are chemical solutions specifically designed to infiltrate the microscopic gaps and crevices between two mating metal surfaces that have seized or are difficult to disassemble.

How do penetrants work?

Penetrants work primarily through capillary action by being drawn into the smallest spaces and gaps. Once inside, they break down corrosion and other contaminants that may be causing the parts to stick together.

What types of penetrants are available?

There are many different types of penetrants available, but the two most common are oil-based penetrants and water-based penetrants. Oil-based penetrants create a barrier between the two surfaces, preventing further corrosion, while water-based penetrants are more effective at displacing moisture.

How do I use penetrating oil?

Apply the penetrant directly to the area you are trying to loosen and let it sit for a period of time (usually 10-20 minutes). Then use a wrench or other tool to try to loosen the part.
