Ave!
Kevin.... do you wax sand patina coins ?
Good question.
Excellent question, indeed!
But first, let's address the question on cleaning 'sandies', shall we?
When cleaning 'desert patina' issues, your best bet to address them wet as possible.
Often times, these super-dry
type issues, even after a 7-day soak in DW, fail to 'get wet'...or that is, muddy. Not to worry, though, just continue to keep the coin wet with water, or spit (better) as you address it with a common DP or a DDDP (better). In most cases, a toothbrush is a waste of time, IMO. No Gringgotts mixes!
Concerning
patina below the sand, again, in most cases, it should be near jet black. But, unfortunately, we sometimes come across a coin as seen below.
A lovely
Constantius II Ae 2

Antioch.
In cleaning this issue I screwed up by over-cleaning the obv, despite all of the advice that I mentioned above.
Well, no one's perfect....
In this case, the coin DID NOT have the smooth black
patina as normally found in these 'DP' issues, but instead a 'green', water-based
patina under the sand. I then halted any further cleaning.
As for
Ren Waxing DP issues; no problem. The RW will bring out all the colors of your coins with no harm.
DO NOT, UNDER ANY CIRCUMSTANCES, APPLY DELLERS TO DP COINS! Trust me....!
All for now,
Kevin
