It’s all too easy for our car cup holders to get dirty. The hard part is cleaning it. This easy hack we found on cleverly.com is the easiest way to clean those far reaching parts of your cup holder.
Grab a cup (one that fits snugly in your cup holder) and put a sock around it. Spray the sock with disinfectant or your cleaner. Then, put the cup into the holder and twist around with light pressure to get the dirt. Remove the cup, and voila. Your sock has wiped up the dirt and grit!
