Scale from Kitchen faucet

[77Overlander]

My 77 Overlander is spitting large amounts of green metalic scale from the kitchen faucet. I know this stuff is metalic because it will sit in the bottom of a dish or the sink will barely rinse off the surfaces. Don't have this problem in the bathroom. This stuff will plug up the aireator in a heart beat.

The single handle faucet doesn't supply any hot water and I'm wondering if it's just the cartridge? I have a replacement but haven't installed as I'd like to not have a rats nest project on my hands w/o feed back from this forum.

TIA

I think the water heater needs to be flushed, then the lines , then the faucet may need to be disassembled. this is classic heated water scale build-up. I get a little each season, and I flush out each season. it is standard hard water + dissimalar metal oxidation.
