Aliphatic naphtha is recommended for wipedown of cleaned surfaces just before painting because it effectively removes oils, greases, and residues that may interfere with paint adhesion. This solvent is less aggressive than stronger solvents like acetone and mineral spirits, making it suitable for preparing surfaces without causing damage to underlying materials or paint. Aliphatic naphtha has a slower evaporation rate compared to other solvents, allowing it to thoroughly clean the surface without evaporating too quickly, which ensures that the surface remains free of contaminants and ready for optimal paint adhesion.

While acetone is a strong solvent that can clean surfaces effectively, it may strip some finishes and is sometimes too harsh for delicate materials. Ethanol can work as a cleaning agent but is often less effective than aliphatic naphtha for this specific purpose because it may not dissolve all types of oils or contaminants effectively. Mineral spirits are useful for cleaning but can leave oily residues that may affect paint adhesion if not fully removed. Therefore, aliphatic naphtha provides a well-balanced option for achieving a clean surface ideal for painting.
