Vinegar is a reliable cleaner that is widely used in kitchens and bathrooms. As it is gently acidic, it removes dirt effectively without risking damage to the finish of faucets and other delicate surfaces. With this in mind, it is logical to think that it should be suitable for use in dishwashers.
Many people have successfully used vinegar as an alternative to regular dishwasher detergent. Its acidity means it is ideal for removing hard water stains, which are alkaline.
However, some experts advise against using too much vinegar in a dishwasher. It could do unseen damage to the appliance or leave a strong vinegar smell coming from the unit or your dishes even after the cycle ends.
