Breville the Descaler 4 pk

Took about 15 minutes for the powder to fully dissolve and clear the limescale from my kettle, and the water flows perfectly again. No harsh smells during use, which I appreciated.

My espresso machine was pulling weak shots and making a weird noise, so I finally ran this powder through a couple of cycles. The difference is night and day, the limescale is completely gone and the steam wand is back to full pressure. Four packets is plenty for regular upkeep, and the acid formula

Used this to descale my espresso machine and it worked well, though I had to use two packets for a thorough clean. The powder dissolved fine but left a faint smell for a bit. Solid value for the pack of four.
