Marble worktops in a kitchen is highly desired by most homeowners, but it also demands good amount of maintenance. Marble is porous and can be easily damaged if any acidic substance falls over it. This includes usage of vinegar, bleach or other such acidic cleaners. Mild soap mixed with water can easily clean a marble worktop. Vinegar on marble countertops can leave a dull finish to the stone and hence it can deplete faster.
