Citric Acid

£2.50

Think of citric acid as a powder form of white vinegar… Its number one use is for descaling. Derived from the acids in citrus fruit (no surprise there, then) put a couple of spoons in your scaley kettle and fill with water just above the element and switch on. Enjoy the fizzing. Switch off before it boils and rinse the kettle out. Sparkle, sparkle.
