I recently bought a Philco Predicta that of course doesn't work.  The plastic picture tube cover was badly covered with a mold or something on the front and back.  I cleaned it off (it took kerosene to get it off) but the plastic is badly yellowed.  So if I ever get it working the black and white picture will be black and yellow.  I've tried bleach, white vinegar, hydrogen peroxide, baking soda, even fine sanding.  Nothing is working.  Does anyone know a way to get rid of the yellow?
