I've seen suggestions for lacquer thinner, Oven cleaner, acetone, MEK, Oxiclean, carb cleaner, denatured alcohol, gasoline, Toluene, Xylene, Naptha, turpentine and diesel fuel.
For every post where someone claims it's worked like a miracle I see where someone says it was ineffective.
I need to be cautious so as not to remove the paint or fade it.
There has to be a way that the professionals use that does not involve hours of tedious labor and yet preserves the paint. Any suggestion?
