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 minutes or less 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.

bygger just nu en egen Braumeister och undrar lite om kopplingar. Har svetsat på rostfria muffar men undrar om man kan använda lite mässingsbussningar också. kan ju inte vara farligt då man använder mässing i installationer med färskvatten. tacksam för era tips.
