Social media post reveals meaning behind triangle symbol on clothing care labels

A recent social media post has sparked interest in clothing care labels, particularly a triangle symbol that many people misunderstood. The triangle indicates whether bleach can be used on the garment, with variations showing different bleach options. The post highlighted a care label from trousers bought in Japan, which included several symbols. Users learned that a triangle with two lines means no bleach is allowed, while an empty triangle indicates bleach is safe to use. This newfound understanding of laundry symbols has surprised many, with users sharing their past mistakes and expressing a desire for better education on the topic.
