It’s happened to all of us. You’re reaching for your coffee mug, taking a sip, and then you notice it – a long scratch running the length of the cup. You try to remember how it got there, but you can’t. It’s just always been there. But is a scratched coffee mug safe to drink from?

If your coffee mug has only superficial scratches, don’t worry; those are harmless. However, if the scratches are deep or if they run into the mug’s material (creating a network of tiny cracks), they could leach harmful elements into your coffee. The severity of the leaching will depend on the material of the mug.

For example, if you have a glass mug with deep scratches, it’s more likely that harmful elements will leach into your coffee than if you have a ceramic mug with shallow scratches. In general, though, scratched coffee mugs are safe to use as long as the scratches are superficial.

How to inspect the scratches in our coffee mug

If you can’t seem to get the scratches out of your coffee mug, there’s an easy test you can do at home to see if they’re superficial or if they run all the way through the glaze. All you need is some baking soda and water.

Mix 2-3 tablespoons of baking soda with 1-2 tablespoons of water to make a soft paste. Use a microfiber cloth to scoop some of the paste and gently rub it on the scratches. You may need to add a few drops of dishwashing soap to get the paste to stick. Rinse the mug in fresh water. If the scratches are superficial, they should be gone. If they’re deeper, they’ll still be visible. This test is especially useful if you’re not sure whether you should continue using the mug or not.

What are the dangers of scratched coffee mugs?

Scratched coffee mugs can pose a serious health hazard. The scratches provide a perfect breeding ground for bacteria, which can then be transferred to your mouth and cause infections.

In addition, the scratches can also trap coffee grounds, which can make your coffee taste bitter and can also cause tooth decay. If you regularly drink coffee from scratched mugs, it’s important to take steps to protect your health.

First, make sure to wash your mug with hot water and soap before each use. You should also avoid using abrasive cleaners on your mug, as they can exacerbate the problem. Finally, replace your mug if the scratches become too deep or numerous. By taking these simple precautions, you can enjoy your coffee without putting your health at risk.
