Dry ice low-temperature blasting car washing method

The invention discloses a dry ice low-temperature blasting car washing method. According to the method, the discharge amount of VOCS gas in the traditional car washing process is effectively reduced through dry ice washing, a traditional chemical washing mode can be completely or mostly replaced to a certain extent, corrosion and damage to the washed car and pollution to the environment caused by chemical washing are avoided, mechanical damage and scratch to the washed car caused by mechanical washing are avoided, and the service life of the car washing machine is prolonged. And the equipment precision is reduced due to repeated loading and unloading. The cleaning efficiency can be improved through dry ice cleaning; the equipment damage is reduced; high-temperature equipment can be effectively cleaned; reducing or reducing the use of solvent; the safety of workers is improved; the maintenance efficiency is improved; meanwhile, an organic solvent is not used, and dry ice is adopted to replace the organic solve
