'''Brasso''' is a [[metal polish]] designed to remove [[tarnish]] from [[brass]], copper, [[chrome plating|chrome]] and [[stainless steel]]. It is available either directly as a liquid or as an impregnated wadding pad also known as '''Duraglit'''.

==History==
{{Tone|section|date=September 2025}}
Brasso originated in Britain in about 1905. [[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.<ref>{{cite book | last = Church| first = Roy A. |author2=[[Andrew Godley]]| title = The Emergence of Modern Marketing| publisher = Routledge| year = 2003 | page = 30 | isbn = 0-7146-5390-X}}</ref>

Because of the hydrocarbon components in the mixture it had a [[flash point]] of {{cvt|72|F|C}} ([[Abel Close test]]) and so was classed by [[List of railway companies involved in the 1923 grouping|railway companies]] as [[dangerous goods]]. This classification allowed them to charge more for distributing Brasso around the country. Reckitt's appealed to the companies asking for the polish to be recategorised in the hope of reducing costs, but the railways disagreed. As a result of this in 1913 the case was taken to the [[Railway and Canal Commission|Railway and Canal Commissioners]] for a decision. After a hearing lasting two days the commissioners decided in favour of the railways, and Brasso remained classed as a dangerous substance for the purposes of railway transport.<ref>{{cite journal |last1=Taylor |first1=Bill |title=Surprisingly Dangerous Goods |journal=Backtrack |date=July 2018 |volume=32 |issue=7 |page=405}}</ref><ref>Railway And Canal Commission."

The polish grew in popularity in Britain, becoming widely available, eventually replacing the previous paste-style polishes. It has undergone very few changes in either composition or package design over the past century. Cans are often collected as a typical example of classic British advertising design.

In the US, the current Brasso product is not the same as the legacy product. The manufacturer, Reckitt Benckiser, has not produced the impregnated wadding version of the product for many years. The formula changed in 2008 to comply with US [[volatile organic compound]]s law, and the metal bottle was replaced by a plastic one.

In 2010, Brasso brought out a new product, Brasso Gadgetcare. Gadgetcare is a versatile, non-abrasive gel that can be used on everything from LCD TV screens, laptop screens, computers, smart phones, and PDAs. The [[plastic bottle]] is {{cvt|50|ml|usoz}} and is sold with a microfibre cloth.

Brasso is abrasive and will wear metal over time. The [[National Trust]] recommend alternative cleaners.<ref>{{Cite web |url-status=dead |archive-url=https://web.archive.org/web/20210620125238/https://www.nationaltrust.org.uk/stoneywell/features/homemade-delights- |url=https://www.nationaltrust.org.uk/stoneywell/features/homemade-delights- |title = Metal care at Stoneywell |archive-date=20 June 2021}}</ref>

Brasso has also been used to polish out scratches in plastics:
*It has been used to polish CDs, DVDs, screens, and pools to repair scratches. It is a mild solvent and an extremely fine abrasive, so when applied to the reflective surface of the disc and rubbed radially (in straight lines between the edge and centre), it can smooth scratches and reduce their effect.<ref>''Understanding and Servicing CD Players'', Ken Clements, [https://books.google.com/books?id=QHKIiNYlwSoC&dq=brasso+cd+repair&pg=PA177 p 177]</ref><ref>''Big Book of Apple Hacks'', Chris Seibold, [https://books.google.com/books?id=jKY-rDoJx3wC&dq=brasso+cd+repair&pg=RA1-PA585 p 584 – 585]</ref><ref>[http://users.fulladsl.be/spb2267/restorecd/restorecd.htm Restoring a Damaged CD<!-- Bot generated title -->] {{webarchive |url=https://web.archive.org/web/20081224024912/http://users.fulladsl.be/spb2267/restorecd/restorecd.htm |date=24 December 2008 }}</ref>

Brasso has been successfully used to take minor (white) heat marks out of [[French polish]]ed wooden surfaces. The fine abrasive cuts through the surface and allows the solvent into the wax and lacquer layer. The surface should be properly cleaned and waxed after this treatment.

Brasso has been successfully used to restore [[Bakelite]] (telephones, appliances, etc.).

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