Bright dip is a mixed-acid immersion process for copper and brass. It is not a coating — nothing is deposited on the part. The acid removes oxide and surface haze and levels the metal itself, leaving a smooth, bright, reflective surface. Gleco runs bright dip at our AS9100D and ISO 9001:2015 certified Texas plants, alongside plating, so a brighten-then-plate sequence stays under one PO.
Bright dip is a mixed acid immersion — hydrochloric, sulfuric and nitric — that strips oxide and surface haze from copper and brass and levels the metal underneath. Nothing is deposited on the part. It is a chemical brightening process, not a coating.
Copper and brass. We do not bright dip aluminum. If you need a bright appearance on aluminum, talk to us about mechanical polishing ahead of Type II anodizing instead.
Yes. A bright dip leaves copper and brass oxide-free, which makes it a common prep step ahead of tin, nickel or silver plating. We run both in-house so the sequence stays under one PO.
