What solvent is recommended for wipedown of surfaces just before painting?

• A. Aliphatic Naptha
• B. Mineral spirits
• C. Xylene
• D. Acetone

Answer: (A)

When prepping a surface for paint, the goal of the wipe-down solvent is to remove oils, greases, and contaminants without leaving a film or reacting with the surface, and it should dry quickly so the primer can adhere properly. Aliphatic naptha is a light hydrocarbon solvent that effectively dissolves oils and greases and evaporates rapidly, leaving little to no residue. This makes it a good balance between cleaning power and surface compatibility, so the paint bonds well to the surface afterward. Mineral spirits clean similarly but evaporate more slowly and can leave a film if not wiped well. Xylene is stronger and can be harsher on certain plastics or coatings and may cause swelling. Acetone dries extremely fast and can be too harsh for some surfaces, potentially affecting plastics or adhesives and leaving less control over the wipe-down. So aliphatic naptha is the best choice for a wipe-down just before painting because it cleans effectively while drying cleanly and minimizing residue that could interfere with adhesion.
