What is the correct cleaning method for the polished chrome portion of the piston assembly?

The recommended cleaning method for the polished chrome portion of the piston assembly involves wiping from top to bottom with a lint-free cloth using hydraulic fluid. This method ensures that the delicate chrome surface is cleaned effectively without scratching or damaging it. Hydraulic fluid is beneficial because it not only helps in cleaning but also provides a light layer of protection, preventing corrosion and enhancing the performance of the piston assembly.

Using a lint-free cloth avoids introducing particles or fibers that could potentially scratch the polished chrome surface. The top-to-bottom wiping motion is important as it helps maintain a uniform clean and reduces the risk of dirt or debris being pushed into crevices or back onto the surface. This technique is essential in maintaining the operational integrity and longevity of the piston assembly in the aircraft.
