This classic cleaning method relies on the mild abrasiveness of the powder and its natural ability to lift stubborn tannins without scratching standard ceramic, glass, or porcelain surfaces.

Coffee is notorious for leaving behind dark, unsightly rings and overall discoloration inside favorite mugs. Over time, the natural oils and dark pigments in roasted coffee beans bond to microscopic imperfections in the glaze of a cup. While standard dish soap and a sponge are usually sufficient for daily washing, they often fail to touch old, set-in coffee rings. Baking soda offers a safe, chemical-free alternative to harsh commercial cleaners, breaking down the residue mechanically and chemically without leaving behind toxic fumes or artificial scents.

Before beginning the cleaning process, collect a few simple household items. You will need a standard box of baking soda, a small container or bowl to mix a paste, a few drops of water, and a brush suitable for scrubbing dishes.

Avoid wire brushes or extremely abrasive scouring pads, as these will permanently ruin the smooth finish of your drinkware, making them even more susceptible to future staining.
