It is important to adjust white balance to remove any unflattering "color casts" so that objects which appear white in person, will also appear white in your image. Color Casts can be caused by variant lighting environments and land you with an image that is too cool (more blue) or too warm (more yellow). Adjusting white balance is how you will best achieve those true whites that take toning so well!
While you can always just rely on the "Auto" option for White Balance in Lightroom for desktop or mobile, you can also take the time to manually adjust this, or you may decide that a preset setting like "Indoor General" is a better fit for your image and your desired edit than "Auto". For both desktop and mobile one of the best manual options for quick white balance selection is to use the eyedropper tool next to the White Balance mode selector. With the eyedropper, you simply select the place on the image with the most neutral toning available.

White Balance is found under the Basic panel in Lightroom Classic, and the Color menu in Lightroom CC/Mobile.
