Start with the least aggressive route
Use a soft damp cloth with mild detergent for stubborn grease, then wipe away residue and dry. Do not spray into the cavity, flood openings or use harsh cleaner, abrasive pad or metal tool.
Judge only when dry
A remaining patch may be residue, pigment, dye loss, finish change or material damage. Stop if a hidden test changes colour, gloss, texture, shape or adhesion.
