ive thought about this too...however most of the time the chrome plated brass fittings/valves are used for cold water only. aka ice makers, toilet supplies, ect. my thoughts were similar to above and the heat would cause the chrome to crack and flake. i sau follow the below instructions, and use regular brass if you dont want to go stainless
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.
