Madison Cars 1947 - 1950

It will take a while, but the safest way is spray some 409 or Fansastik on a Q-tip and work little sections at a time. This will protect the paint and lettering. DON'T run under water, that will fade the paint.

Thank you, Chuck, for the recommendation.  I believe neither 409 nor Fantastik contain bleach.  Was trying to avoid using anything with a bleaching agent.  Also wanted to avoid any product that might damage the 75 year old plastic window strips.  Regards.  Walt
