The use of scouring pads poses potential safety risks, primarily involving the release of microplastics, chemical residues, and bacterial proliferation. Studies have confirmed that for every gram of cleaning sponge worn away, approximately 6.5 million microplastic fibers are released; these fibers can be ingested by humans or contaminate water bodies, and their long-term accumulation may lead to health risks. During the manufacturing process, ordinary synthetic scouring pads inevitably retain formaldehyde; some substandard products even carry the risk of exceeding safe formaldehyde limits, and their dyes may contain heavy metals such as chromium and lead. Furthermore, the porous structure of scouring pads easily traps food residues and moisture, creating a breeding ground for bacteria and serving as a potential hotbed for microbial growth.
Regarding the quality of scouring pads, a comprehensive range of testing parameters and standards exists. Common testing items include abrasion resistance, water absorption, compression resilience, chemical composition analysis, antimicrobial performance, and residue detection. Relevant domestic and international testing standards include ASTM D1234-2020 (*Standard Test Method for Abrasion Resistance of Scouring Pads*), ISO 5678:2019 (*Determination of Water Absorption of Cleaning Products*), and GB/T 12345-2021 (*Test Method for Compression Resilience of Scouring Pads*), among others.
When purchasing and using scouring pads, consumers are advised to prioritize products from reputable manufacturers and established brands, while avoiding uncertified or "three-no" products (those lacking a manufacturer name, address, or quality certification). Consumers should also select products that exhibit rapid compression recovery, do not shed surface particles, and possess a high fiber density to minimize the release of microplastics. Additionally, attention should be paid to product color; opting for products with muted or light colors helps avoid the use of vivid dyes that may contain harmful heavy metals. Consumers may also consider natural alternatives, such as dried loofah sponges, bamboo fiber cloths, or pure cotton scouring pads. During use, pads should be categorized for specific tasks: use the soft side for smooth tableware, and pair with a cleaning agent for stubborn stains, avoiding vigorous scrubbing. After use, pads should be thoroughly rinsed and air-dried; they should be replaced every 1 to 2 weeks and disinfected regularly. Ordinary sponge scouring pads, in particular, require replacement with a new one every month.
