After ridge removal, what should be used to wipe the cylinder to prevent metal chips from spreading?

• A. Dry Cloth
• B. An oily rag
• C. Paper towel
• D. None Of These

Answer: (B)

After ridge removal, tiny metal chips can be scattered inside the cylinder and into nearby passages. The cleaning method should trap and hold those chips rather than dispersing them further. An oily rag is the best choice because the oil makes the chips adhere to the rag, keeping them from being pushed along the bore or into oil passages. A dry cloth or paper towels tend to push or shed particles and fibers, which can spread debris rather than remove it. Using an oily rag helps ensure the cylinder is left clean and minimizes the chance of chips causing damage later. Just remember to handle oily rags safely and dispose of them properly to reduce fire risk.
