Lightly-colored marks, typically in the shape of rings, are caused by the bottoms of cold glasses or hot plates and mugs resting on a wood surface. In both cases water is the culprit, in the form of condensed moisture (cold) or steam (hot).
Mix a solution of one part white vinegar to ten parts water, then dampen a microfiber cloth or mop with the solution. Wipe the floor gently, avoiding excessive moisture. For stubborn haze, use a commercial hardwood floor cleaner specifically designed for engineered wood.

Vaseline can be a great quick fix if you are trying to remove a light water stain from wood. It's a good solution for wood table tops because they are a high touch surface!

Lightly sand the cloudy areas with fine-grit sandpaper. Reapply a thin coat of polyurethane, ensuring proper drying conditions. Using a dehumidifier in the work area helps reduce moisture and prevent cloudiness. Ensure each coat of polyurethane is fully cured before applying the next layer.
To remove a stain from wood without sanding, use a mixture of baking soda and water or a wood-specific cleaner. Apply gently with a soft cloth and rub in the direction of the grain. For tougher stains, a bit of white vinegar can help. Avoid abrasive methods to prevent damage.
Some DIYers recommend leaving the surface of the wood coated in mayo for several hours or even overnight to let the oils penetrate the material. But I was able to get the job done in just a few minutes.
“When water stains on the finish of wood furniture show up as those white cloudy rings or marks, this coloring is a sign that the moisture is in the finish and hasn't yet reached the wood,” DeWitt says. “If the stain looks dark, versus light and cloudy, this is an indication that the stain has reached the wood itself.
