Mrs Martin’s DESCALE Citric Acid 500g


Citric acid is a natural and effective descaler that can be used to remove mineral buildup from various appliances, including coffee machines. South Africa generally has hard water, and descaling is an essential maintenance step, that helps to prolong the life of your appliance and improve its performance.
To use citric acid as a descaler, you will need to dissolve the powder into hot water in the correct ratio. The recommended ratio is two tablespoons of citric acid to one liter of hot water. Once the powder is dissolved, you can pour the solution into your appliance and let it sit for a while before rinsing it out.
Citric acid is an excellent alternative to harsher chemicals that can damage your appliance or leave behind harmful residues. It is also biodegradable and safe for the environment.
