Product Description


Bottle of 500ml Delonghi EcoDecalk descaler
Gives you 5 descaling doses.

Limescale accumulation in your coffee machine will adversely affect both the quality of the coffee and the durability of the machine. Why is this? It is because of limescale. Limescale build-up means that the coffee takes longer to produce, as the heat transfer to the water is affected. This reduces the quality of your espresso. The limescale will continue to build-up and thickening before eventually becoming a blockage that can damage your machine.

De'Longhi advises you to use De'Longhi EcoDecalk descaler for the De'Longhi espresso and coffee machines.

De'Longhi Ecodecalk descaler:
• Is highly effective at removing limescale and will not damage your machine.
• Will ensure the ideal flavour of your coffee whilst increasing the durability of your machine.
• Is cleansing and anti-bacterial.
• Is completely biodegradable.
• Is not corrosive or abrasive.
• Is simple and easy to use.

Step 1. Pour 1 dose (100 ml) of De'Longhi EcoDecalk descaler into the water reservoir.
Step 2. Add one litre of water to the reservoir and stir the De'Longhi descaler / water solution.
Step 3. Follow the directions in the manual of your De'Longhi coffee machine.
Step 4. After descaling, wash the water reservoir with clean tap water and rinse your machine.

Using this product significantly reduces the likelihood of premature breakdown from scale build-up.

Excellent Product and ServiceReview by Dean
I've bought from a few times now and they are a top company. I recently bought some descaler for my DeLonghi coffee machine. It was reasonably priced, the product was exactly as described AND it was delivered in less than 24 hours after placing my order. Excellent all round company selling quality products.

Good ProductReview by Gigi
Arrived promptly, and as stated, my Delongi won't work when the descale light is on, so I was very pleased. Gave it 4 stars as no instructions on how to use it, so looked on the web. Found the price was misleading as a surcharge was imposed for a small order, plus of course the postage. (Posted on 06/04/2019)

It worksReview by Mully
It works but I feel the instructions were poor, it was a guess about how much water to product to use and the instructions were written really small, not good for old eyes, but the product works thankyou (Posted on 26/01/2019)

How much water do I put per 100ml of descaler thanks Lindsay
Please could you advise me if the Delonghi EcoDecalk has a date after which it is not effective. My current bottle has a 2015 date on it but has not worked to descale my coffee machine. Do I have to purchase another bottle? Thanks for your attention.
