Need to remove yellow stains from fabric? Try blue LED light

We all have that favorite piece of clothing, and we're all familiar with the sinking feeling when we spill something on it.

But now, new reports have revealed a simple way to remove pesky stains.

ACS Sustainable Chemistry & Engineering researchers found that high-intensity blue LED light can help remove yellow stains.

The method is said to be effective at removing stains from orange juice, tomato juice and sweat-like substances on multiple fabrics, including silk.

“Our method utilizes visible blue light in combination with ambient oxygen, which acts as the oxidizing agent to drive the photobleaching process,” said Tomohiro Sugahara, the study’s corresponding author. “This approach avoids the use of harsh chemical oxidants typically required in conventional bleaching methods, making it
