Consumer Council Warns: Melamine Foam Sponges Release Carcinogens When Heated
HK01 · 1 SOURCESabout 2 hours ago7 MIN

Summary
Hong Kong's Consumer Council has issued a comprehensive safety warning about melamine foam sponges, commonly known as "magic erasers," in its latest CHOICE Magazine. The council cautions that these popular cleaning products pose significant risks to both health and household surfaces when misused. Research indicates that the sponges' hard honeycomb micro-structure can scratch delicate surfaces, while exposure to heat, acids, or oils triggers the release of cancer-causing chemicals. Experts are also raising alarms about microplastic pollution generated during normal use.
Key Points
- The Consumer Council published safety warnings about melamine foam sponges in the latest issue of CHOICE Magazine, citing expert analysis and research findings
- The honeycomb micro-structure removes stains purely through friction rather than chemical dissolution, making it extremely abrasive on delicate surfaces
- Temperatures exceeding 60 degrees Celsius, acidic substances like vinegar or lemon juice, and cooking oils can destroy the sponge's structure, releasing formaldehyde (a Group 1 carcinogen) and melamine (a Group 2B possible carcinogen)
- Professor Keung Yim-mei (姜艷媚), Head of the Department of Health and Life Sciences at the Hong Kong Institute of Vocational Education, strongly advises against using these sponges on food, fruits, pacifiers, or drinking straws
- Online beauty trends promoting the use of melamine foam for teeth whitening or facial cleansing are extremely dangerous, as the abrasive action can permanently damage tooth enamel and strip the skin's protective layer
- Research from 2024 shows that just one gram of worn melamine foam releases approximately 6.5 million microplastic fibers, with global online sales generating an estimated 49 trillion microplastic fibers annually
- The Environmental Protection Department confirms that Hong Kong's sewage treatment facilities achieve high microplastic removal rates, though source reduction remains the fundamental solution
- The Consumer Council recommends using conventional yellow-green sponges with cleaning agents as the primary choice, reserving melamine foam only as a last resort, and always using cold water with gentle motions
Why It Matters
With millions of melamine foam sponges sold in Hong Kong annually, the widespread misuse of these products poses both personal health risks and environmental concerns. The Consumer Council's warnings serve as a critical reminder that even everyday household items require careful handling, and the呼吁 for manufacturers to develop eco-friendly alternatives reflects growing public demand for safer, more sustainable cleaning solutions in the city .
