<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:black">That’s great advice Nikki. I’d just add that polishing is always a destructive process, removing metal along with the corrosion. Even for solid copper, brass
and silver, you will lose surface decoration and introduce small scratches that can be disfiguring and can actually increase the likelihood and extent of further corrosion. Best to leave it unpolished. If polishing is absolutely necessary, then store/exhibit
with scavengers such as Pacific Silver Cloth afterward, to inhibit further corrosion. Otherwise, once you polish, you’ll probably have to keep polishing.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">This is something that is often debated between conservators and curators. At some point they should not get any darker. Once an even tarnish layer
or patina forms on the surface they should remain the same colour as long as they are handled with gloves and not exposed to other contaminants. Metals are very sensitive to oils from our hands and as they will etch into surface and cause localized tarnishing.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I would not polish them because I like the tarnished aged look. Every time you polish something you are stripping a thin layer of the metal off.
This is not a problem if it is solid copper, brass or silver. If it is only plated then at some point you will strip away all the copper/silver leaving the base metal to show through. Polishing can be very time consuming and will increase the chances of damage
due to increased handling. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Saying that, if you have something that you know never would have been allowed to tarnish in its working life then you might wasn’t to keep it
polished. <o:p></o:p></span></p>

about whether to clean and polish them or to allow their age to show.<o:p></o:p></span></p>
