How to remove stubborn stains on ceramic badges?

To remove stubborn stains from ceramic badges, try the following:

Toothpaste wipe
Materials: plain white toothpaste, soft damp cloth or towel.
Operation method: Apply proper amount of toothpaste to the stain and wipe gently with a damp cloth or towel. The tiny particles in the toothpaste can act as an abrasive and help remove stains without causing too much damage to the ceramic surface. After wiping, rinse with water and dry with a clean soft cloth.
White vinegar soaking method
Ingredients: White vinegar, small bowl or basin (according to the size of the badge), soft brush.
How to operate: Pour the white vinegar into a bowl or basin, and put the badge into it to soak for a period of time, generally soaking for about 15-30 minutes. For particularly stubborn stains, the soaking time can be extended appropriately. After soaking, gently scrub the stain with a soft brush and rinse with clean water. The acidic component in white vinegar can break down some stains, making them easier to remove.

Baking soda paste
Ingredients: Baking soda, water, soft cloth.
Instructions: Mix baking soda with water to make a paste. Apply the paste to the stain on the ceramic badge and wipe gently with a soft cloth. Baking soda has a cleaning and decontamination effect and can effectively remove stains. After wiping, rinse with water and dry.
Professional ceramic cleaner
Material preparation: Purchase special cleaning agent for ceramic cleaning, clean soft cloth.
Operation method: According to the detergent instructions, spray or apply the appropriate amount of detergent on the stain, and then gently wipe with a soft cloth. This type of cleaning agent is usually targeted, can effectively remove a variety of stubborn stains, and is relatively mild on ceramic materials. After wiping clean, rinse with water to remove the residue of detergent and wipe the badge dry.
