Teeters,
When I mentioned Brazzo, I should have clarified that I had only heard from my man about the cost of the stuff increasing. I was issued with a tin of the stuff on enlistment as Aircraftman 2nd Class in 1963. Within days, bag of anodised buttons appeared (subsequently replaced at private expense by the high domed version) and, thereafter, I found little use for my button stick or the brazzo.
One now uses a cloth impregnated (in the nicest possible way) with some harmless stuff to clean the bling.
O-D
