Rinsing is one of the most important operations in coin cleaning cycle, yet when I talk to people who do cleaning probably the most neglected... and will cause poor results... your rinse water must be kept clean!!
Im sorry to say that most coins have different types of gunk on them, and really need different types of chemicals to properly remove them....this is the true difference betweeen what I am reading here "a dip" verse true correctly done coin conservation... one day when I have more time, perhaps I can write out some suggestions but did you know that in many coin cleaning applications , a pre cleaning with hot water would have significant value as a pre cleaner to remove soils, salts, dust, fumes and some lubricants... let me say that I have over the years studied this area quite a bit, and I really dont recommend the average person doing it.... with that said each type coin based on its metals would have its own cleaning agents that I would recommend.... I am not sure what you wish to "dip" but if you post more info, I might be able to add some additional info...
