A fibrillated fibre or microfibre cloth, lightly moistened with water, available from Volvo dealers, is recommended for cleaning interior parts and surfaces.
Do not scrape or rub stains. Never use strong stain removers, either.
Do not use solvent that contains alcohol when cleaning the glass for the driver display.
Keep in mind that high gloss surfaces are easily scratched. Clean these surfaces with a clean, dry microfibre cloth using small, circular motions. If needed, dampen the microfibre cloth with a little clean water.
