Vintage Brown

How do I get rid of spots on a white chiffon dress vintage?
I found this great vintage white chiffon dress but the only problem is that it has two large spots on both sides of the dress. the spots are brown and very noticeable against the white cloth. How do I get rid of these spots?
NO BLEACH VINTAGE FABRIC !!!!!!!!! OM-freakin-G Bleach !!!!! eat the tissue of the vintage. Especially if it has not been careful and doesn't sound like it has. Want to try and enjoy OxyClean or a mixture of baking soda and white vinegar. If that fails, try to spot a wet paste Ajax or Comet and let it set then increase in cabbage, NEVER put cold water and clothing in a dryer. If all else fails, dye. It is better to have a robe dipped one is going to crumble apart.
