Looks like a gate valve with some calcium carbonate scale.
and what looks to be some sort of dried landlord repair fluid.
Not that the landlord needs to be really broken before you’re able to see the benefits of using the repair fluid.
For slightly broken landlords, don’t waste perfectly good repair fluid on them.
Ahh yes. Landlord fluid.
Copper carbonate -- it is greenish. The white stuff in the front is paint, I think.
It'll pick up some copper oxidation on brass fittings.
