Rancilio Silvia Boiler
Hoping for some help with rebuilding the Rancilio Silvia that I picked up off a generous fellow CS.
Picture below shows the inside of the boiler and hoping some can help with what this is (corrosion?) and if / how it can be fixed or simply nothing to worry about.
General question, anything else I should be checking or be cautious of during the rebuild?
Extra photo of inside boiler.
The fine black stuff of the floor is what came out of inside boiler, any idea of what that is?
Looks to be just a light covering of scale Martin with maybe some additional mineral deposition...
Just descale via the instructions of a decent descaling product, such as the one from Cafetto, for example.
