Cleaning technique

[del]

this is a repost of an older thread as it may have been lost during the software transfer.


here is a Civil war era button i recently found , its a officer's Connecticut state seal coat button ( rare to find them not dented or pushed in )

just freshly dug with lots of dirt and grime

and heres after a warm soapy water and toothbrush scrubbing , while it is better it could be so much more appealing.

now this is more like it , this is after some water diluted in some CLR (calcium lime rust) remover and a toothbrush . it took only a few moments to get the dirt and grime stains off to reveal the eye popping gilt .

the clr can be harmful to items like copper if it is not diluted right and left too long on an item , be careful with it and practice using it on less valuable items first to understand its properties . you could damage a nice relic or item.

for example i will usually start with a 1/4 clr to 3/4 water mixture ratio dip the toothbrush into the solution and brush it vigorously for a few seconds or until i see the the foam discolor from the dirt. then rinse the item under the water and repeat until i'm happy with the results. then rinse item well pat dry and add a coating or light oil , vaseline or other to preserve the look and keep it from oxidizing and discoloring.

Thanks for the info Dan. I only have one really nice pre-CW button that looks to have some gilt left on it. It has the same appearance as your middle picture. I'm going to see if I can clean it up a bit more with your method. I'll post pics. HH, Dave.

Dave just remember to work with it diluted and in little windows of time at a time , brass buttons can take the clr on them a bit longer but the thin copper two piece ones like civil war era type can get damaged if left on there too long.

I remember seeing this post, thanks for reposting! Where does one obtain CLR? I have a few items that might be candidates for some experimenting. Fantastic results with this item!

Nice tip Dan!! That CLR stuff works! I figured I would try it on a lincoln penny just to see how it works. I'm impressed! Here are the before and after pics. :)

I use a chemical called Awesome they sell it at the Dollar store it the only thing I feel comfortable going in there for lol. It has ethanol in it so it tends to work very well.

Lemon juice also works pretty good too.

Each cleaning techniques have there pluses, The CLR seems to make the gold brighter than the lemon juice, but the lemon juice seems to be gentler on the un-plated areas. The CLR can turn the exposed areas a rough reddish color.
