Cleaning advice please

Post by Ashmeadskernel » Fri Jan 04, 2019 3:39 pm

I am reading David Villanueva’s book “Cleaning coins and artefacts”. He says he uses a Dremmel oscillating engraving tool to clean deposits on coins. I already have a Dremmel type tool with variable speed 10,000 to 30,000 rpm. What does oscillating mean in this context? The term isn’t mentioned in the instructions and of tools offered online, some say oscillating and some don’t. Is this something that I should use?

It just means moving the tool back and forth in a regular rhythm as you work.

There are Dremel Oscillating tools that move in a forward backward motion or side to side rather than a turning motion i think thats what it means.

Go so very carefully.

I have seen many an item lose most of its value both historically and money wise.

I once found a mid 17th century copper penny that looked like a token and was in fact worth 5 figures.

Happy Hunting,

Removing deposits from coins - I can see that some degree of power tool use may be acceptable in some instances of improving an encrusted artifact, I would suggest that use of any powered abrasive tools for the removal of unwanted deposits on coins, has to carry with it a high probability of risking damage to the coin (or self) :-O Personally, I would recommend only using those tools and methods used by conservationists as it's so easy to over-clean (damage) an item by using powered implements. Just my view on the subject.

What SS47 says u;@ , in my opinion (and it is only that - an opinion).

A bit of care, time, patience and elbow grease mitigates the risk brought by such mechanical methods as a Dremmel *shudders*. Mind you, this is from someone who has been known to use eloctrolysis on a silver denarius :)

It's your coin and you proceed as you wish, but personally... I wouldn't use that thing.

I know nothing about cleaning coin's (yet) but after many year's of fossil preparation, conservation and consolidation I'm certain the same advice holds true. If in doubt leave it alone, some things deserve the attention of an expert, practice on low value/broken items and then practice some more! I have seen some very rare (and valuable) fossils destroyed by a combination of good intentions and lack of expertise.
