I use Dawn to wash my truck before applying the zaino polish (they recommend it), because all the old wax and contaminents must be stripped from the paint in order to properly apply the polish. Dawn works awesome here. The activator will not bond properly to the paint if there is old wax on there.DaddyG said:Best way I have found to quickly remove the wax off the black plastic: Take a damp rag, put a small dab of Dawn Dishwashing detergent on it, wipe off the plastic. With a small bit of effort it will take it right off. Just be careful and not get the Dawn on the fresh wax, because it will remove it. Use a good protectant on the plastic when your done, and it will look as good as new. Dawn will remove wax but not hurt the paint.
If I'm applying Carnuba wax, I just use Mcguiar's soft gel wash.
