The invention belongs to the field of cleaning agent preparation methods. The solution comprises a solute and solvent. The solute and the solvent are fully stirred into the solution. The solute is prepared though steps of: (1) material selecting, wherein the material is porous silicate ore; (2) crushing; (3) sieving, wherein particles with sizes of 16 to 20 meshes are selected; (4) modifying, wherein the material is immersed in a modifying agent for 10 to 20 hours; (5) activating, wherein the material is added into special equipment, and a separated-stage heating and heat maintaining process is carried out like that: the material is heated from room temperature to 100 DEG C, and the temperature is maintained for 2 hours; then the material is gradually heated to 420 DEG C, and the temperature is maintained for 4 to 6 hours; and (6) fine grinding, wherein the material is grinded to a size equal to or above 450 meshes. The solvent is prepared through steps of: (1) RO reverse osmosis water treatment; (2) EDI water treatment; (3) frequency conversion activating water treatment; and (4) far infrared activating filter water treatment. According to the invention, pure natural ores and natural plants are adopted, and a German nanometer activated molecular sieve technology is adopted. With an oxide catalyst, harmful gases such as formaldehyde, toluene, xylene, sulfur dioxide, benzene, ammonia and TVOC can be removed with high efficiency. The solution brings no toxicity to human and animal, no pollution to the environment, and no damage to vehicles, furniture, leathers and plastics. The solution can be widely applied in industries such as vehicle, vehicle decoration, indoor, home decoration, and furnishing for removing odors such as toxic odors, livestock and poultry cultivation odors, animal and pet cultivation odors, and footwear odors. An odor removing rate of the solution reaches 99.9% or higher. A suitable temperature of the solution is 5 to 60 DEG C.
