Using vinegar and water as a homemade hardwood floor cleaning solution can have a negative effect on your hardwood floor. It’s important to remember that when you clean your hardwood floors, you aren’t actually cleaning the wood—you are cleaning the chemical finish on the wood. The finish is the protective layer of your hardwood floors.
Since vinegar is an acid, it will actually break down the finish on the surface of your floor, and over time it will reduce the shine and leave a dull appearance. Using vinegar and water to clean floors can also lead to an excessive amount of water on the floor, which can cause swelling and discoloration.
Always use a specially formulated hardwood floor care cleaner to maintain the beauty and look of your floors.
