Brasso

Reckitt & Sons' senior traveller, W. H. Slack, visited the company's Australian branch, where he discovered such a product in use.

Samples from Australian and US producers were then analysed by Reckitt's chemists, and by 1920 liquid polish under the trademark "Brasso" was being sold, initially to railways, hospitals, hotels, and large shops.

[1] Because of the hydrocarbon components in the mixture it had a flash point of 72 °F (22 °C) (Abel Close test) and so was classed by railway companies as dangerous goods.

The formula changed in 2008 to comply with US volatile organic compounds law, and the metal bottle was replaced by a plastic one.

Brasso liquid lists a slightly different mix; C8–10 Alkane/Cycloalkane/Aromatic Hydrocarbons, Quartz, Kaolin, C12–20 Saturated and Unsaturated Monobasic Fatty Acids, Aqua and Ammonium Hydroxide.

Brasso, on account of its ammonia content, has been used as a de-coppering agent in rifle barrels to remove copper fouling.
