Laundry pods offer a convenient, mess-free laundry solution but can leave residue if not used properly. Residue results from pods not dissolving fully due to factors like improper placement, overloaded machines, or cold water. While pods are safe for machines when used correctly, the plastic film they contain raises environmental concerns due to microplastic pollution. Proper usage and awareness of environmental impact are key to benefiting from laundry pods while minimizing drawbacks.
