How to Remove Coffee Stains From Cups Using Baking Soda and Vinegar
What You'll Need Before You Start:
- White Vinegar
- Baking Soda
- Clean Cloth
- Nylon Scrubber Sponge
If white vinegar alone is not enough to remove coffee stains from cups – and smells – from your coffee cup, then you need to add a little baking soda to the mix.
When baking soda and vinegar are combined, the result is a bubbling action that can literally foam away many stains, including tough coffee stains. What's more, this often means that stains will disappear without any help from you – you just stand back and watch the action!
For plastic or acrylic cups that simply won't let go of a strong coffee stain or odor, there's nothing more effective than a baking soda and vinegar combination. Vinegar and baking soda are both natural deodorizers, and when combined, work even harder against tough odors, and coffee is well-known for it's aroma.
However, if you've neglected your cup so long that coffee has formed a thick crust inside (and if you have, shame on you!), then the foaming action may be enough to loosen the crust so that scrubbing and regular washing, either by hand or in a dishwasher, will remove the rest.
To use baking soda and vinegar together to remove coffee stains from your cup:
- Sit the cup in a sink, or, if you have a marble sink, in a dishpan.
- Add one teaspoon of baking soda to the cup.
- Pour a quarter cup of vinegar over the baking soda; for larger cups, use more.
- Allow the baking soda/vinegar mixture to bubble and foam, and let the foam set in the cup for several minutes.
- Pour the baking soda/vinegar mixture out of the cup.
- Wipe the cup out using a clean cloth.
- If any stain remains, use a nylon scrubber sponge to dislodge the remaining coffee stain.
- Rinse well.
- If any discoloration or coffee odor remains, repeat steps 2-8 until the discoloration and/or odor is removed.
