Wright's copper cream

Post by Tallystick »

I've had great results using Wright's copper cream to restore corroded bronze hardware, so I wanted to suggest this product as it's inexpensive and effective. Soaking hardware with siezed mechanisms in a dilute solution of this stuff has worked well in freeing the moving parts. It's sold in my local grocery store for under 3 bucks.

Interesting.

As I'm sure everyone has noticed by now (probably to their annoyance ;), I tend to be curious about things. So I wondered what was in the Copper Cream (I remember polishing silver with Wright's Silver Cream as a kid).

Here is what the MSDS has to say:

Of course then I became curious how that compared to their silver cream...

Their brass polish:

And their metal polish:

I can see they are all different (because... don't you sometimes wonder if you are buying twenty specialty products that could boil down to maybe three that are really different and actually have to take up space?), but I don't know enough about chemistry to analyze the differences.

I think they choose an active ingredient that reacts with the corrosion products to produce a water soluble compound.

The silica is probably used as a mild abrasive.

Plain ol' baking soda works for silver polishing btw.

You could actually use the leftover copper polishing solution as an anti-fungal treatment, as the copper chloride hydrate is a potent anti-fungal hehe.
