Use the least aggressive method that solves the problem

Always begin with the simplest effective method: a clean dry cloth, or a lightly damp one where the material allows it.

Solvents, polishes, cleaners, oils and “universal” products can react with finishes, plastics, rubber, printed graphics, adhesives and treated surfaces. Before applying a product, confirm compatibility with the material and, where practical, test an inconspicuous area.

Shinier does not mean better preserved. The purpose of cleaning is to remove contamination without altering the original surface.
