How can I effectively remove the white residue left by hard water?

To effectively remove white residue left by hard water, you can use a mixture of vinegar and water to clean the affected area. The acidic properties of vinegar help to dissolve and remove the mineral deposits that cause the white residue. Simply spray or apply the vinegar solution onto the surface, let it sit for a few minutes, and then scrub or wipe it away. Repeat the process as needed until the white residue is completely removed.
