Zinc, aluminum, and light‑metal alloys may be attacked — caution is advised. ETC A2 is not suitable for delicate gemstones such as pearls, coral, lapis lazuli, amber, or opals.
Whether in industry, laboratories, workshops, or jewelry care, ETC A2 is the cleaning concentrate for those who pay attention to detail. The ammoniacal liquid formula ensures thorough cleaning and rapid brightening without compromise. Its strength becomes particularly evident on precious and non‑ferrous metal parts: they are visibly brightened and freed from residues.
