Tip 1: use a brand-specific descaler The manufacturer of your coffee machine strongly discourages you to use a descaler other than the own brand. Sometimes, they'll even say that the warranty on your machine is no longer valid if you use a different descaler.
Always use the same brand descaler as the machine or use the Eccellente descalers. Descalers come in many forms (liquid, powder, tablets) but they all have to be dissolved in water to be used. Therefore the easiest is a descaler which is liquid but in the end it does not really matter in which form they come.
However, not all chemical descalers are created equal. Why? Simply put, two significant factors come into play. The various compositions of the deposits built up generally differ due to the water source and therefore need different acidic formulas for the best results.
There are number of Descale Powders / liquid available in the market and you can use any of those for any of the washing machine.
Nearly any coffee descaler will work. It's not unique to capsule machines. Just check your local stores for lactic acid or citric acid coffee descaler. You'll follow the directions that came with the Nespresso machine (can find online if you don't have them) and use the generic descaler.
Vinegar is a very effective in removing lime scale HOWEVER there are a lot of problems which comes with descaling with vinegar: Vinegar (acetic acid) attacts rubber seals and some metals. Boilers will absorp the odor / taste of vinegar. No surfactants to release coffee residues.
Once the descaling solution has gone through the machine, discard it, rinse your carafe with clean water, fill the reservoir, and run two more cycles like this.
Conclusion. Descaling is an essential maintenance task to keep your coffee machine running efficiently and to extend its lifespan. Whether you choose descaling liquid or descaling tablets, both options are effective at removing mineral deposits and limescale.
Baking soda is another very popular home remedy used for descaling coffee machines. Just like vinegar, it is widely used throughout the home. To clean your coffee machine using baking soda, dissolve 1/4 of a cup in 1 litre of water, pour it into the tank, and then follow the same steps as in the previous methods.
To ensure the longevity of your washing machine, it's recommended to descale it at least three times a year. If you know that water is hard in your region, it's best if you do it a bit more often.
As we mentioned earlier, vinegar is one of the best natural descalers in your kitchen. Vinegar is very acidic that combats the limescale of your coffee appliance after regular brewing. Mix vinegar with warm water in a 1:1 ratio and run the brew cycle several times for cleaning.
So, do electronic descalers work? They may, but you will probably find more consistent soft water results with a traditional water softener or water conditioner.
Baking soda is also a highly effective household product for fighting limescale. It neutralizes acids, deep cleans, and releases a pleasant scent. To use it, simply sprinkle baking soda on the bottom of the bowl, let it sit for about 20 minutes, then scrub with a brush.
If the water can't reach its optimal brewing temperature, it is impossible to extract the full flavor from your coffee beans. Mineral scale buildup can clog water flow, and if not removed, can cause a machine to stop working. Your coffee won't be hot enough to enjoy.
Acids used
Notable descaling agents include acetic acid, citric acid, glycolic acid, formic acid, lactic acid, phosphoric acid, sulfamic acid and hydrochloric acid. The calcium salts are soluble and thus washed away during dissolution or solvation.
The water conditioner will slowly eliminate existing limescale as descaled water passes through the system. Still, this process can take months, especially if water consumption is low (it may have taken years for the scale deposits to build up).
Some articles likely mention using common household vinegar to descale, which unfortunately does not turn out to be very effective. Vinegar is very weak and mild acid which is not effective to remove limescale or rust. Plus, you run the risk of leaving a vinegar taste in your machine.
TM 11 is one of the strongest Acid Descalers available and although safe to use, as with most strong chemicals TM 11 requires caution when using, handling and storing.
Citric acid is a naturally occurring acid found in citrus fruits. It effectively loosens and lifts limescale, allowing you to easily rinse away. Compared to harsher descaling agents, citric acid offers several advantages.
Inhalation: Material may be an irritant to mucous membranes and respiratory tract. Skin contact: Contact with skin will result in severe irritation. Corrosive to skin - may cause skin burns. Ingestion: Swallowing can result in nausea, vomiting, diarrhoea, abdominal pain and chemical burns to the gastrointestinal tract.
This Descaler fights to eliminate the lime scale deposited on the drum and other parts of the appliance, thus retaining the condition of the appliance. This descaler enhances the washing quality and increases the lifespan of your appliance. Removes Limescale Deposits. Forestalls Calcium Build Up.
If your coffee machine was not properly rinsed after descaling, coffee might taste acid. To rinse the machine, allow 2 full tanks to percolate through the hot water spout and the boiler outlet.
Failing to descale your coffee machine regularly can lead to several problems. The most immediate is a noticeable decline in the temperature and quality of your coffee, as scale buildup can insulate the heating element, causing it to underperform.
Step 3: Fresh Water Rinse
Empty and rinse the water reservoir and refill to the max fill line with fresh water. When flashing, press the BREW button to start the rinsing process. Once the brew is complete, pour the hot liquid into the sink. Repeat this step two times until the Descale notification shuts off.
