Most coffee machine brands sell their own brand-manufactured descaling solutions, which they recommend as the safest and most reliable for descaling their brewers. Delonghi, is no different!
Vinegar is a cheaper and more accessible alternative for descaling Delonghi. If used correctly, this natural cleaner will remove limescale deposits from the inner components of your Delonghi coffee machine, all while saving you a few bucks in the process.
Is vinegar good for descaling coffee machines?
Vinegar is good for removing limescale from coffee machines due to its high acetic acid content. The acetic acid breaks down the calcium deposits from the walls of the machine’s internal parts, resulting in better-tasting coffee while also solving a host of machine problems usually caused by limescale buildup.
Vinegar is an organic cleaning agent and is, therefore, more eco-friendly compared to commercial descaling products. What’s more, vinegar is cheap and readily available in most homes, thus you don’t have to spend on commercial descalers which are costlier.
On the downside, though, vinegar leaves a strong residual smell that can affect the smell and taste of your coffee. You, therefore, need to rinse off the residual vinegar more thoroughly than you would after descaling with a commercial descaler.
Note: You should run at least three rinsing cycles to wash off excess vinegar after descaling using it to decalcify your coffee maker.
Failure to thoroughly rinse off residual vinegar not only affects the taste of your coffee but can also cause the degradation of the brewer’s internal aluminium components. However, if the coffee machine doesn’t have aluminium parts, there should be no risk of deterioration of components.
Take note that while vinegar will effectively descale your coffee machine, the brand manufacturer may not honor warranty any warranty claims resulting from damage caused to the inner parts by residual vinegar. Most coffee maker brands actually advise buyers to avoid using vinegar if they don’t want to forfeit their warranty coverage.
