Lime scale build-up is a common occurrence in kitchen appliances such as coffee pots, kettles and dishwashers. It occurs when hard water – which contains deposits of minerals such as calcium and magnesium – is dried or heated on the surface of the appliance. Vinegar is a popular kitchen-cleaning ingredient that can be used Melt the grease from the cabinet And descale the coffeepots. However, as good as vinegar is as a cleaner, citric acid is a better, more effective solution for removing limescale from your kitchen appliances.
Citric acid is a natural weak acid present in all forms of citrus fruits and is what gives them their characteristic sour taste. In powdered form, it is used in cheesemaking and preserved foods. For cleaning purposes, a simple solution of 2 teaspoons of citric acid in 500 milliliters of warm water in a spray bottle can be used to clean appliances with limescale buildup.
For descaling, you can use citric acid directly inside coffee pots or tea kettles, and also Clean your dishwasher. To do this, fill the detergent cup with a few ounces of citric acid and run the washer through a full cycle. The citric acid will stick to the limescale, removing it from the surface and dissolving it, leaving you with a sparkling clean dishwasher interior without the harsh acetic smell associated with vinegar.
How Citric Acid Chemically Descales Your Kitchen Equipment
But how exactly does citric acid work? Homemade Coffee Pot Descaling Cleaner? To check that, we have to get down to the molecular level and look at the chemical reaction that occurs when citric acid meets lime scale. There are two processes at work here: acidification and chelation. Acidification will dissolve accumulated minerals, while chelation will bind any remaining ions together so that they are washed away when the cleaning solution is drained.
This is the main difference between using vinegar and citric acid to descale kitchen appliances. Vinegar does not have the chemical structure to create chelation, and therefore only uses acidification to dissolve built up lime scale. The main point is that the acidity of vinegar decreases the moment it comes into contact with the more alkaline minerals in the lime scale. As such, you will need to use the vinegar several times before you remove all the limescale.
Citric acid, by contrast, should only take half an hour to clean a coffee pot and a single cycle to make the dishwasher sparkly. Outside of the kitchen, citric acid can also be used as a water softener for showers and tubs, bathroom sinks, and laundry, though only for white items because it can have a bleaching effect.
