You can't clean it. It's being eroded away on purpose, to prevent
damage somewhere else.

buying new parts or heaters.
Replace it.

so the OP got a used tank hopefully for free...........
by the time he replaces the anode, replaces the elements and cleans
the sludge out of the tank.....
Has he wondered where that sludge came from? Almost certinally from
the inside of the tank which is nearly rotted out

I thought the sludge was mostly dissolved minerals in the water, and
that the tank is glass-lined and didn't rot? No?


Now he has a old tank, thats less efficent than a new tank with high
efficency foam.

So his tank has cost probably cost nearly as much as a brand new cheap
short warranty tank



is the anode aluminum or ZINC?
