Excellent product from carpro. However, children need to be careful. It is very powerful. It removes salt from windows and bodywork but leaves a white residue. Then it needs to be treated with something else to remove it. I use Ajax for windows and the result is perfect, even on the bodywork. I use different cloths or wash the same one to alternate between them. I don't know if you have years of salt, but it does a great job on a weekly basis. A relaxed pass on the entire car with spotless and then with Ajax.
