What negative effects can moisture have on lubricants?

Moisture is detrimental to lubricants primarily because it can cause corrosion and promote the growth of microorganisms. When water is introduced into a lubricant, it can lead to the formation of rust and other forms of chemical degradation of metal components, which significantly affects the lifespan and effectiveness of machinery. Corrosive reactions can weaken the metal surfaces of machine parts, leading to increased wear and potential failure.

Additionally, moisture provides a suitable environment for microorganisms, such as bacteria and fungi, to thrive. These microorganisms can create sludge and other byproducts that disrupt lubrication properties, degrade the lubricant, and lead to blockages or other operational issues.

In contrast, moisture does not enhance the performance or characteristics of lubricants; instead of improving viscosity and flow, or lubricating film strength, it negatively influences their function, causing machinery to operate less efficiently. Moreover, the idea that moisture has no impact on lubricants is misleading, as its presence is directly linked to several adverse effects.
