UrnexDezcal Activated Scale Remover - 7 oz - For Use on Commercial Boilers and Heating Elements of Coffee and Espresso Equipment

Arrived fast and packed well. First time using Dezcal I've always used a weak vinegar and citric acid solution I made up. Thought I would try a commercial product this time. I mixed it at about 1.5 tablespoons per quart of water. Pack should be good for four cleanings or so.This seemed to work great following directions. Following directions, I cleaned and descaled two espresso machines. First I mixed the solution then pumped into the machine enough solution that I could tell it filled the boiler. Then I let it sit for half an hour. You could see the lime deposits flushed out as I pumped out the Dezcal after the half an hour. You must flush out the Dezcal several times with clear water because it tastes terrible.My machines are both over 8 years old but I do maintain them by using only filtered water and descaling every 6 months or so. This keeps them running fine and coffee tasting good.

I previously used vinegar to flush my tankless water heater. I will never use vinegar again after finding this descaler. I always thought vinegar did the trick. It was not till I used the Dezcal that I learned the vinegar did nothing in removing my limescale. I added 1 packet of Dezcal to each gallon of water used. FYI, this stuff is mostly Citric Acid, so you will find it to be safe and non-toxic

We used this to clean our tankless water heater. This product cleaned really well, as there was sediment residue after cleaning and the tankless heater is only one year old. I highly recommend this product.

Worked well, have clean clear pipes.

I used half the bag for one descale of a Keureg. Couldn't get the descale light to go off, just "brewing" with the solution in the tank. Then read the manual, and there is a model-specific button combination to get it into descale mode. Now, that works. A tank of this, then a tank of clear water, and all is well. Oh, watch the dust when you handle this stuff. It is irritating if you breathe it.

Works great but be careful to keep away from stainless steel, it's can make spot on your coffees machine steel.

Great product and cheaper than individual packages. Use 1/4 package for 1 quart of water (instructions say to use full package for 1 gallon).Beware the acid in the solution may permanently tarnish mirror polished stainless steel surfaces such as spoons or the outside of a milk frothing pitcher! I suggest mixing the powder into warm water by using a plastic spoon and avoid using a polished stainless steel frothing pitcher when purging the solution from the espresso machine.

Use this to descale my electric kettle. Getting several uses out of one bag
