/ck/ - Food & Cooking

I think I fucked up. I had picrel for about a year now and recently went on vacation, when I came back I realized I had left some coffee grounds in the tray and they obviously were modly as fuck.
Problem is even the machine itself seems to be a bit moldy, at least the coffee tastes pretty off, probably doesn't help that I was neglecting maintenance even before, I tried using the flush program you usually use to descale a few times and cleaned every bit I could including the brewing unit and while it did help it's still noticeable.
Is there a way to save it or do I have to get rid of it?
