Stilllearning Posted August 9, 2019 Report Share Posted August 9, 2019 In Eric Newby’s book The Last Grain Race, he mentions cleaning brasswork with caustic soda. Link to comment Share on other sites More sharing options...
Johny London Posted August 9, 2019 Report Share Posted August 9, 2019 Couldn't help noticing that some misguided Fertan did a sterling job of cleaning up some copper pipe the other week when I was de rusting in the engine bay - wonder if it has the same effect on brass?

Nightwatch Posted August 9, 2019 Report Share Posted August 9, 2019 (edited) Rust converters have phosphoric acid in them. Phosphoric Acid is an excellent descaler for loos and taps and cleaner for stainless steel, brass, copper and Crome. Without turning it black like hydrochloric acid does. Coca Cola also has Phosphoris Acic in. Drop a two pence piece in a small amount and leave it for an hour.

zenataomm Posted August 9, 2019 Report Share Posted August 9, 2019 When the value of scrap non ferrous rocketed 10 years or so back, the eyes of covetous scrotes alighted upon mushroom vents and tiller extension bars. That's when I resorted to painting them, they have remained so ever since and I regret not doing it 36 years ago. I could have got gotten a lot more boating in.

But coke cleans it very nicely. Not sure where the extrapolating comes into this. Link to comment Share on other sites More sharing options...
Neil TNC Posted August 9, 2019 Report Share Posted August 9, 2019 Back some 20 years ago, when our boat was new I always used T-Cut. It took no effort at all to get shiny brass. Link to comment Share on other sites More sharing options...
Johny London Posted August 9, 2019 Report Share Posted August 9, 2019 I think t cut and brasso are pretty much interchangeable! Link to comment Share on other sites More sharing options...

Tesco Value, or similar, at 17p (?) for 2 litres would work as well. Does it also work to get rid of limescale? Link to comment Share on other sites More sharing options...

I was taught by instructors that Phosphoric acid was the friendly acid with regards to tarnishing of Crome and stainless steel. Link to comment Share on other sites More sharing options...

I second this - My gran told me that if you want to "bring back" brass then the best thing is brown sauce. Slather it on and leave it for a bit then with a toothbrush or something similar nothing too scratchy give it a good scrub into all the nooks and then wipe it off with kitchen roll and clean with your regular metal cleaner. I hear people say tomato ketchup but I've tried it a couple of times and it's never as good as HP. Edited August 10, 2019 by Tumshie Link to comment Share on other sites More sharing options...
