CARPRO IronX Limescale is an acid-based cleaner for removing iron particles and hard-water mineral deposits from suitable exterior surfaces. Combines two decontamination tasks, but may damage ceramic coatings.

Wash the surface, shake the bottle and test a small area first. The supplier specifies 3–5 minutes of contact time; do not allow drying, especially in sunlight. Gently agitate with a damp, soft tool if needed and rinse thoroughly.
