Its always been expensive and time consuming to get small parts plated by local platers or by sending them to out of area platers. A lot of the plating firms only do large runs, and even small platers often charge outrageous prices for small items..sometimes $25-50 minimum charge. Gold plating has become outrageously pricey.

The plating process starts with a gold strike treatment to prevent the exchange reaction. The same strike bath can be used for the first rinse after the gold plating. The current density depends a lot on the processing method; that is, 0.2-0.4 Adm −2 is used for barrel plating and 0.5-1 Adm −2 for rack plating.

Yes, if the gold plating is thin, then the gold-plated layer can be removed using vinegar. Vinegar is an acidic solution, which means it will slowly dissolve the layer of plated gold. Ordinarily, Aqua Regia, a mix of hydrochloric and nitric acids, dissolve gold, but vinegar could also get the job done, as long as you are patient.
