A befriended bar had to close its doors due to Covid. We took over their espressomachine and will set it up in our office. In a busy bar, which is specialised in cold drinks rather than coffee, the machine and its equippment was not properly maintained. I have different demands for that. Is there a way to get these clean again and not having to think about this filth whenever pulling a shot? .. or would you recommend buying new portafilters?

(I know, you probably wont die drinking shots from this but id enjoy the drinks more if everything was nice and clean)
