Mugs have a stubborn brown stain after a few months of daily coffee drinking. Luckily, there is a very cheap, quick way to clean away old coffee stains without any harsh chemicals or special cleaners.
All it takes is some baking soda. Sprinkle a little baking soda onto the bottom of your stained cup, add just enough water to form a paste, and scrub. The gentle abrasion of the baking soda will get rid of stains in a matter of minutes.
If you’ve started to notice a brown residue on your coffee mugs, try adding an occasional baking soda scrub to your cleaning rotation. It’s easy and it works… We guarantee it!
