Story summary

Japanese researchers discovered that high-intensity blue LED light removes yellow stains from fabrics more effectively than bleach and UV light.
The study, published in ACS Sustainable Chemistry & Engineering, tested stains from sweat, orange juice, and tomato juice.
Blue light oxidizes stains using ambient oxygen, offering a sustainable alternative to bleach.
The method is safe for delicate fabrics, such as silk and polyester, with no damage observed.
Researchers aim to commercialize this technology after conducting further safety tests.
