Why is it important to use two separate dry wipes when cleaning a surface?

Using two separate dry wipes when cleaning a surface is crucial to prevent contamination from being moved around. The primary goal of the cleaning process in painting and refinishing is to create a clean, contaminant-free surface to ensure proper adhesion of paints and coatings. When a single wipe is used repeatedly, it can spread dirt, grease, and other contaminants from one area of the surface to another, potentially compromising the quality of the finish.

By utilizing two separate dry wipes—one for initial cleaning to pick up dirt and contaminants and the second for a final pass to pick up any residues—you maintain a cleaner surface. This practice enhances the overall quality and durability of the finish applied afterward, minimizing the risk of defects such as fisheyes, peeling, or lack of adhesion.

The other options, while they may seem relevant, do not directly address the primary purpose of using two wipes in this context. The emphasis is on effective contamination control to ensure an optimal surface for painting, which is paramount for achieving professional results in the refinishing process.
