Originally bought this to descale Breville Expresso machine, but machine not yet due for descaling so use it on Breville kettle. Just use a small quantity of fluid and see the brownish deposite at bottom of kettle disappear magically in 10 to 20 seconds... very clean without manual intervention. As we cannot see inside (steel boilers) of the expresso machine, cannot comment on that but based on its working on steel kettle it surely is a good and effective product for its purpose.

Great descaler. Bought for our coffee machine but works brilliantly in the electric kettle using just a small amount with water.
