Pay extra attention to the corners and edges where streaks tend to hide. If necessary, use a second filter to polish the mirror to a perfect finish.
For stubborn spots, you can slightly dampen a corner of the coffee filter with water and rub the area gently before drying it with the rest of the filter.
When This Helps Most
This trick is particularly useful when you need the bathroom to look its best, such as before having guests over or when you want to enjoy a pristine space. It’s also a great quick fix for those rushed mornings when you need your mirror to be clear for last-minute touch-ups.
