Degreasers are special chemical formulas designed to break down and clean oil, grease, and thick, sticky fats that ordinary shampoos or dish soaps cannot remove. These types of substances are extremely important in industrial, automotive, and household cleaning applications.
This article will delve into the mechanism of action, types of degreasers, and safe usage precautions.

Mechanism of Action of Degreasers
Generally, grease or lubricating oil stains are insoluble in water and adhere tightly to surfaces. Therefore, degreasers use two main chemical mechanisms to work:
1. Surface tension reduction (Surfactants): Surfactants reduce the adhesion between the oil stain and the surface, allowing water to penetrate and break down the grease into smaller particles for easier removal.
2. Solvent action (Solvents): Chemical solvents react to directly dissolve the dense molecular structure of the lubricating oil, transforming the sticky, ingrained stain into a liquid that can be wiped or washed away with water immediately.

Types of Degreasers
Currently, cleaning agents are categorized according to their primary chemical base to suit different applications, as follows:
• Solvent-Based Formulas: Typically contain hydrocarbon compounds. They are most effective at removing heavy grease, soot, and deeply embedded engine oil stains. Commonly used for cleaning engine parts, auto repair shops, and heavy machinery.
• Water-Based Formulas: Primarily use surfactants and alkaline substances. They are highly safe, non-flammable, and more environmentally friendly. Suitable for cleaning factory floors, oil stains in kitchens, or parts that need protection from harsh chemicals.
• Bio-Based / Green Degreaser Formulas: Made from natural raw materials such as microorganisms, plant extracts, or biodegradable surfactants. They are very safe for users, biodegradable, and are becoming increasingly popular in modern industries.

How to Choose the Right Degreaser for the Job and Surface
When selecting a cleaning agent, it is necessary to consider the type of material to prevent damage:
• Metals and Iron: High-concentration solvent-based formulas work well for quickly removing stubborn stains.
• Plastics and Rubber: Avoid harsh oil-based formulas as they may cause plastics to become brittle or rubbers to swell and deteriorate. • For painted surfaces: Concentrated chemical solutions may strip the paint or coating. Always dilute with water according to the ratio indicated on the label before use.

Precautions and Safety Instructions
Because many cleaning agents are corrosive or volatile chemicals, operators should follow these instructions:
• Wear protective equipment: Always wear nitrile gloves, safety glasses, and a chemical mask to prevent skin and eye irritation.
• Work in a well-ventilated area: Oil-based cleaning agents often accumulate vapors. Working in an open area will help reduce inhalation of toxic substances.
• Store away from heat: Some solvents have a low flash point and are flammable. They must be stored in a cool, dry place away from sparks.
