Degreasing techniques are methods used to remove grease, oil, and other contaminants from surfaces. Common techniques include using solvents, detergents, and mechanical methods like scrubbing or blasting. Solvent degreasing involves applying chemical agents that dissolve grease, while detergents help emulsify oils, making them easier to wash away. Another effective method is ultrasonic cleaning, which uses high-frequency sound waves in a liquid solution to dislodge contaminants. This technique is often employed in industries like automotive and manufacturing, where clean parts are essential for optimal performance. Proper degreasing ensures better adhesion for coatings and improves overall equipment efficiency.
