OK! Og er det så eddikesyre (acetic acid, som jeg selv oversatte i en tidligere tråd), den gode Palmer skriver et andet sted på siden. Eller er det også "bare" eddike?

Hej allesammen. Jeg ved hvor jeg kan læse om det... Men jeg forstår det ikke?? http://www.howtobrew.com/appendices/appendixB.html Er der en ædel personage der vil hjælpe mig med at forstå hvordan jeg renser messing for tungmetaller? Det er nok mest oversættelsen af kemikaliernes navne jeg ikke fatter? <snip fra siden> Cleaning Brass Some brewers use brass fittings in conjunction with their wort chillers or other brewing equipment and are concerned about the lead that is present in brass alloys. A solution of two parts white vinegar to one part hydrogen peroxide (common 3% solution) will remove tarnish and surface lead from brass parts when they are soaked for 5-10 minutes at room temperature. The brass will turn a buttery yellow color as it is cleaned. If the solution starts to turn green and the brass darkens, then the parts have been soaking too long and the copper in the brass is beginning to dissolve, exposing more lead. The solution has become contaminated and the part should be re-cleaned in a fresh solution.</snip fra siden> Altså... To dele hvad? med en del hvad? som er 3% opløsning?
