Here's a long-winded account of various testing methods. I've not heard of your product, but here in the U.S., Simichrome and 409 are frequently used products.

Thanks for the link. Autosol is the UK equivalent of Simichrome and works out a lot cheaper to buy locally. Similarly, it is used to polish metalwork on cars. We dont have an equivalent to 409 here as far as I'm aware.
Some of the testing results are positive such as smell and sound, just the colour is puzzling!
