Aqueous composition, the method for manufacturing this water-based composition, and removal stench are reduced and/or inhibit to be described using this Aquo-composition. These compositions are utilized in conjunction with hydrogen peroxide, copper source II, and nonionic surfactant and alcohol provide efficient and stable stench removing, reduction and/or composite inhibiting. The composition is particularly useful as aerosol combination for effectively removing stench, reducing stench and/or inhibiting especially from open position, such as landfill and closed domestic environment, such as at home. Stabilized hydrogen peroxide solution is also described, is a kind of stable addition copper (II) salt.
