Tea is a hot beverage that over time can leave unsightly brown stains on your favorite plastic cups. Usual methods of cleaning, such as warm water and dish soap, are not enough to remove this tough stain, and scrubbing with steel wool may leave deep scratch marks. Chlorine bleach is effective, but will fade colors and degrade plastic over time. Baking soda is a safer, more environmental friendly substance that effectively removes most tea stains from plastic cups without any risk of damage.
