IMPRESA[20 Pack] Espresso Machine Descaler Tablets - Large 4 gram Descaling & Cleaning Tablets for Breville, Jura, Miele & Other Espresso Makers – Remove Mineral Build-Up - Coffee Machine Descaler

I bought this and cleaner tablets and now use both with great results. My only complaint is how long it takes to dissolve the tablets in hot water prior to using it. I admit I am guessing this is necessary as I can't imagine it dissolving in the units I have during a cleaning or descaling cycle. But the gunk comes out, the units work great (I have 3 and have used them on all), and because the cost is now reasonable I am keeping up with the maintenance.

Works well - my only observation is that the tablets are very hard and take a ling time to dissolve. My machine requires you to dissolve the tablets before putting in the machine and these tablets take a long time - particularly in cold water. I break up the tablets and place in hot water, reheating in the microwave as necessary.

Never fully dissolve. Not sure if they even work. Even tried dissolving in boiling water and no help. Ended up throwing away and buying liquid descaler.

Fast delivery

This is a good value but the tablets take hours to dissolve. Descaling your coffee maker shouldn’t be an hour long process. Switched to liquid descaler.

Good

Annoyingly does not dissolve - no matter how hot or how much water you use soooo I figured out a trick: use a wooden mallet to smash and crush it before adding to a little boiling water then once dissolved, add rest of water amount needed. I won’t buy again bc annoying extra step but this is the best way to use if you’ve already purchased.

good price....Does the job
