My bathtub faucet plunger that diverts water to the shower head wasn’t working anymore so I couldn’t shower. I bought a new one with chrome finish to match the existing hardware in the bathroom. Installed it

Then I decided to CLR douse the water valve and decorative plate and get rid of some hard water staining. It dripped onto the new faucet which clearly wasn’t made of the same material because it instantly oxidized.

So that was infuriating.
