Do not use fabric softener when washing. Wash with similar colours and keep away from high heat sources.
Use the cloth slightly damp with clear water or a suitable glass/interior cleaner for general cleaning, working in overlapping passes. For final polishing, use the cloth dry to remove any remaining streaks or haze. It can also be used dry for dusting sensitive displays and high-gloss trim. After use, machine-wash at up to 40°C and air dry.
