Using washing soda in a dishwasher is generally not recommended. Washing soda, also known as sodium carbonate, is a highly alkaline substance, and it can be too harsh for dishwasher use. Here's why:
Risk of Damage: Dishwashers are designed to work with specific types of dishwasher detergents, which are formulated to be effective in removing food residues and stains while being gentle on the dishwasher's internal components, such as rubber seals and metal parts. Washing soda's high alkalinity can potentially damage these sensitive parts over time.
Foaming: Washing soda can produce excessive foam when used in a dishwasher, leading to possible overflow and mess inside the dishwasher or even leaks.
Streaks and Spots: Washing soda may not be as effective as specialized dishwasher detergents in preventing streaks and spots on dishes, glasses, and utensils. Modern dishwasher detergents often contain surfactants and other ingredients tailored to leave dishes spotless.
If you're looking for an alternative to commercial dishwasher detergents, you can use a combination of baking soda and citric acid. This mixture can help in cleaning dishes effectively without causing damage or excessive foaming. However, it's essential to consult your dishwasher's user manual to check if using alternative detergents is allowed without voiding the warranty.
For optimal results and to ensure the longevity of your dishwasher, it's best to use detergent specifically designed for dishwasher use. These detergents are formulated to work with the dishwasher's wash cycles and are generally safer for the appliance and your dishes.
