There are a few things you can do to remove yellow stains from white car paint. The first is to use a bucket and pour a small amount of water onto the stain. Then use a cloth or a vacuum cleaner to suck up the water and place it over the stain. Let the vacuum cleaner work for about 10 minutes, then take the cloth and rub it around the stain. Finally, use a hairdryer to dry the area.
