“A cut lemon was left on my granite countertop and it created a big, white blotch.”

The fix: First, an explanation. The acid in lemon can corrode stone, leaving behind a white residue that’s similar to rust on metal. The bad news is that this is a tough stain. The good news? It is removable. Linda Cobb, the author of the Queen of Clean book series ($11,, offers the following four-step plan. (1) Make a paste of 2 tablespoons baking soda and 1 teaspoon hydrogen peroxide (add more peroxide as needed until the paste becomes spreadable). (2) Using a washcloth, scrub the stain with the paste for 5 minutes. (3) Coat the stain with a thin layer of the paste and cover with plastic wrap; let sit overnight. (4) In the morning, when the paste has dried, remoisten the area with hydrogen peroxide, then wipe with a paper towel. Rinse with water and pat dry. Repeat if necessary.
