Well, Dawn will definitely clean them up. That's some strong stuff. Years ago I was an automotive painter. I did all the high dollar stuff. Rolls Royce, Jags, Porsche etc. We told all the customers never to use Dawn to wash their car with if the were in to waxing them because it takes the wax right off. Nowadays there are all the specialty car washes designed not to take the wax/polish off.
