What is used to clean the surface of the material you are sealing?

Using solvent and clean wipes to clean the surface of the material you are sealing is essential for ensuring that the surface is free of contaminants that could affect the sealing process. Solvents are specifically designed to dissolve oils, grease, and other residues, creating a clean surface that enhances the adhesion of the sealant.

Clean wipes complement the use of solvents by providing a lint-free and controlled way to apply the solvent without leaving behind fibers or debris that could interfere with the seal. This method is widely recognized in aerospace assembly because it effectively prepares surfaces for sealing, ensuring that the joint integrity and the performance of the seal are not compromised.

Other methods, such as using water and soap or alcohol with paper towels, can introduce residues or may not adequately remove more stubborn contaminants. Oil and a cloth are not appropriate for cleaning surfaces in this context, as oil can create a barrier that prevents proper adhesion of the sealant. Hence, solvent and clean wipes are the optimal choice for preparing surfaces before sealing in aerospace applications.
