rancillio boiler material?
Im looking to de scale my boiler on a rancillio classe 8, however this is the first non copper boiler ive done and i cant figure out what the boiler is made of. I know citric acid will ruin the finish on a plated boiler. Im not sure if this is plated or stainless, is there another procedure i should be following to preserve the finish. Since the boiler came non attached filling it was not really an option, the only thing i can thing of at this point if i cant submerge it is to buy plugs for every hole and fill it from the top.
Looks like nickel plate to me, try to get some light into the boiler and look in through one of the other holes to see if you can get a look at the internal walls, generally only the exterior of the boiler will be plated (as far as I know at least)
It's copper, and ".....generally only the exterior of the boiler will be plated....."
