Cleaning glass and mirrors can be a tricky job, especially when you care about what you see in that mirror.
When cleaning glass and mirrors, never use a swirl motion. This can cause steaks to show up in the glass or mirror when light hits it. This can cause awkward conversations during a dinner party.
To get a perfectly cleaned glass surface or mirror that will leave everyone in awe, make sure to swipe the surface vertically (top to bottom) first. Then swipe the surface horizontally (left to right). This will leave the glass or mirror perfectly clean with no embarrassing streaks.
