The probability is very low for the virus to infect people through contaminated clothes. The general public does not need to disinfect clothes if they have not been to hospitals, visited patients or contacted people suspected to have symptoms. Although alcohol will not corrode clothing, it is highly combustible. If sprayed on clothes, it becomes easier for them to catch fire in case of high temperatures, open flames or static electricity. So it is not suggested to spray alcohol on clothes.
