Common Characteristics
Elma Ultra Clean cleaning concentrate is cyanide-free and mildly alkaline. It gently cleans gold, platinum or iridium jewellery (also with precious stones) in immersion baths with or without ultrasound.
Elma Ultra Clean reliably removes wax, resin, grease, polishing agents, machining emulsions, sweat and dust, and gives an ultra - bright shine to gold jewellery.
