How to clean black spots in ceramic cups?

March 19, 2023

Nowadays, many people in our lives drink water from ceramic cups. In fact, when we use ceramic cups, do we occasionally find some small black spots on them?. So, the question is, how do you clean up the black spots in the ceramic cup. Generally speaking, small black spots on ceramic cups are harmless. If you see them as small black spots on the green body itself, they are usually caused by the combustion of a small amount of iron impurities in the green body.. In addition, use ceramic cups to make tea, juice, coffee, etc.. After use, there is dirt on the glass and sometimes small black spots appear, which can affect our health. Therefore, it is important to clean the glass frequently.

1. Clean with fruit peel skillfully.

"These black spots can be easily removed with orange and lemon peel. We just need to boil the cup and lemon peel in water and take out the cup several times: like apples and other fruit peels, we cannot use the last method.". To clean, we only need to dip a little salt in the peel, then wipe the cup to remove the black spots..

2. Clean quickly with toothpaste.

First, we rinse the inside and outside of the cup with clean water, then apply a little toothpaste to the cup, then scrub it, and then rinse it with clean water.

3. Salt water.

In fact, we can also use salt to clean. We dip our fingers in a bit of salt and brush back on the black spots, quickly cleaning them.
