Most people ruin clothes not because of bad detergents — but because they ignore the laundry bleach symbol.
That small triangle on your clothing label literally decides whether your fabric will stay intact… or get permanently damaged.
Understanding the bleach symbol on clothes is essential if you want to:
- Keep whites bright
- Avoid discoloration
- Prevent fabric weakening
- Use bleach safely
