Nucleic acid cleaning agent and application thereof

The invention discloses a nucleic acid cleaning agent and application thereof, and belongs to the technical field of disinfection and cleaning. The solution A is a CuSO4 solution, and the concentration of the CuSO4 solution is 0.14 g/L to 16.43 g/L; the solution B is an H2O2 solution, and the mass fraction of the H2O2 solution is 0.03%-3%; the molar ratio of the CuSO4 to the H2O2 is 1: 1. The nucleic acid cleaning agent can be applied to nucleic acid removal, disinfection and sterilization of the surfaces of instruments and equipment made of carbon steel, copper, aluminum and stainless steel. The inactivation logarithm value of the nucleic acid cleaning agent to human coronavirus 229E is greater than 4.00; the killing logarithm values on staphylococcus aureus and escherichia coli are both greater than 5.00; the killing logarithm values of a sample infected with staphylococcus aureus and a sample infected with escherichia coli are both greater than 3.00; and basically no corrosion is caused to carbon steel she
