Prevent blisters

When you’re breaking in a new pair of shoes, stick a cotton ball inside wherever it’s rubbing against your skin to add some cushioning and keep your feet pain-free. If a blister has already cropped up, just use a cotton ball as a barrier between the wound and your footwear.
Remove water spots

Over time, taps can get caked with mineral deposits from the unfiltered tap water. To dissolve those white marks, soak a few cotton balls in a solution of equal parts white vinegar and water, and place them on the area for several minutes. Rinse the tap and dry with a soft cloth.
Deodorise your fridge

If your refrigerator has lingering odours from rotting food, dampen a cotton ball with vanilla extract and place it in the back of your fridge. It will act as a natural deodoriser leaving your fridge smelling fresh.
