There are two ways to clean white work clothes that have been dyed black, the most common of which is to use vinegar for cleaning. It is to drop vinegar on the blackened area, wait for 10 minutes, and then clean it with soap. The stains will not only be clean but also leave no traces. This method is suitable for newly stained work clothes, but it may not be as effective over time. It is recommended to clean white work clothes with white vinegar to avoid leaving vinegar marks.

The second cleaning method is to use a damp towel dipped in cigarette ash for cleaning. This method is also very simple. We use a damp towel dipped in cigarette ash to repeatedly wipe the stained area. Remember to move gently, otherwise it is easy to damage the work clothes. After wiping, rinse thoroughly with clean water. You can also wipe the stain with cigarette ash soaked with your fingers. When using this method, after wiping with cigarette ash, use a flexible cleaning agent for cleaning, and ensure that wet work clothes are not immediately ironed, as this will leave stains on the work clothes.
