I read a post that sounded very positive using boiled linseed oil to clean copper coins (unfortunately I've been unable to locate the original post again :icon_scratch: ).

The poster stated that he would use a paper towel soaked with boiled linseed oil, fold it in half, place the copper coins to be cleaned inside, place a weight on top to compress the paper towel onto the coins and let it sit for a week. After a week the paper towel would be stuck to the coin crud and when pulled apart the crud would stick to the paper towel and the coin would be clean. Sounded like a great idea, so I decided to try it, but I couldn't find linseed oil and instead tried WD40.

Today was the unveiling day, unfortunately it didn't appear to have the same results as using boiled linseed oil :tongue3:

If anyone uses the boiled linseed oil method, whats specifically about it makes it better then other types of cleaning oils?

I did use WD40 to clean a pair of copper flying wings I found over the summer that were encrusted in tar (looks like they were stuck in asphalt at one point) and the WD40 did a great job of breaking down the tar.

Thanks,
Brian

Never tried either, but I know WD40 is basically a fish oil derivative with some thinners and a propellant, shouldn't be harmful on most things you can use other oils on. i think the problem with WD40 is that people think it is a lubricant, and it is not. The propellant an dthinner was probably what removed the tar.

Linseed oil can be found by the paints and paint thinners in most stores.

I also know the method described with the paper towel works very well with olive oil as well.
You are most educated . WD40 is not a lubricant.

There is NO water in WD 40, it is a water displacer.
That's what WD stands for.

"Water Displacement - 40th Attempt".

50%: Stoddard solvent (i.e., mineral spirits -- primarily hexane, somewhat similar to kerosene)
25%: Liquefied petroleum gas (presumably as a propellant; carbon dioxide is now used instead to reduce WD-40's considerable flammability)
15+%: Mineral oil (light lubricating oil)
10-%: Inert ingredients

I didn't really learn anything about cleaning coins from my post, but I learned a LOT about WD40 :thumbsup:

I watched a guy use WD-40 in his car detailing business. It worked very well without having to use
so much elbow grease. He used it to remove stains from upholstery and carpet and also to clean
the road grime off the wheels.

I even tried it on my own vehicles whenever I wanted to do an extra good job of cleaning them.
