KRUPS F054 Descaling Powder for Kettles Coffee and Espresso Makers Fully Auto Machines EA8442 And EA8250

I was skeptical about this product given how poorly my coffee maker has been performing of late. Mind you, I have a Krups IL Caffé Bistro Model 867, which is at least 14 years old, old enough that I forget exactly which year I got it as a gift for Christmas. In any case, It has been a trusty coffee maker for all of that time up until the last month when it started to do a lot of gurgling/percolating and overproduction of steam. It was also taking at least 45 minutes to an hour to make a pot and I would lose about two cups of water in that time due to the steam. I was worried I would have to purchase a new coffee maker until I saw the decalcifier as an option. The instructions that are in my manual indicate 4 cups (32 oz.) of water (comes up to the "7" marker on the side of the pot) to dissolve the product into, though the instructions were geared for the espresso maker on the unit (rarely used on my part). I did what others have done in their reviews, which is to run about half of the solution through the system, switch the system off for at least 10 minutes, and then switch it back on to run the rest through. I immediately started to see little white pieces of crust show up in the pot, which I assume were the calcium/mineral deposits. I flushed the system twice with water and decided to use the second pack of decalcifier given the age of the machine and the fact that I'd never cleaned it in this way before. I'm going on my 4th pot of water to flush out the second cycle and I'm still seeing the mineral deposits showing up in the pot after the water passes through. I'll probably keep flushing the system until I stop seeing the calcium chunks, though thankfully with a filter in the mix they won't make it into the brew anyway. The best part is that the brew time is much improved, down to about 15 minutes for 12 cups (I overfill the 10-cup pot), AND, the perpetual gurgling an sputtering has gone away!

Bought this to clean a Krups FL700D Electric Tea Kettle, hoping it would be the right one to clean it. Luckily I kept my instruction manual for the tea kettle, but I was nervous to use this, as it said not to use citric acid, and this product appears to have some type of acid. The instructions were also vague because it did not specify the amount. So I crossed my fingers hoping it would work. I love my tea kettle but the hard water scaling was getting worst every day and I was concerned the kettle would stop working, and life without tea is just not an option. I used the hard water test strip and it showed 2 red blocks so I figured I should use half the amount. I filled the kettle up to the max fill line with cold water and added 1/2 a packet. I dissolved it for about 30-45 seconds until the stains disappeared and that's it! It looks brand new. I should mention the kettle was cold and I did not turn it on at all, it was done with cold water only and the appliance was off.

This is a must have I you have a Krupa Super automatic machine. You won’t use it frequently but gent the time comes you’ll need it ASAP. Pros: Odorless Easy to use Keeps your machine as new Cons: Kind of expensive

This is a great product. I just wish there were instructions. The box says to follow the instructions in the manual that came with your Krups coffee maker. The manual that came with my Krups coffee makers says to follow the instructions that come in the descaller kit box . . .

I had been getting the clean alert for months and using vinegar but it wasn't working. I used the descaler and the alert went away.

I have a Krup Bistro combination coffee maker and espresso machine, and the coffee was starting to take over an hour to brew 10 cups. I tried vinegar and other coffee maker cleaners sold in stores. The machine is over 12 years old and no longer being made, but we love it so much that I went online and researched products to clean it and found this item. It came to me in three days, tried it following the instructions given by another poster, to dilute it in water; I used half a pot with one packet, started the brew cycle, stopped it mid-stream, let it sit for 15 minutes, then finished the cycle. After that I ran two pots of plain water through to clean it out. Ten cups of water came through in less than 10 minutes, just like when the machine was brand new. This is the best product ever!

The product is fine, but the provider sent an open box that was damaged

My neighbor was giving her Krups cappuccino maker to charity and I asked if I could have it. She said that it didn't work because the water no longer came out, and she had tried to clean it and nothing worked. She gave it to me and I ordered this product. I followed the directions for the coffee maker I found online and ran the cycle once with the descaller and three times after with just water. Now it works great. I haven't decided if I should tell my neighbor or not!
