Vinegar
Vinegar has become a popular cleaning solution because it’s both inexpensive and natural. But all-natural doesn’t mean problem-free. Because of its high acidity, vinegar can damage many surfaces in your home.
It will permanently dull the appearance of stone countertops like marble or limestone, and it will damage the finish on a hardwood floor. Before you use vinegar to clean your household surfaces, do your research to see if these areas of the house can stand up to the cleanser.
