Natural Oxidation
Yellow stains from oxidation don't have a smell and persist despite regular cleaning. Oxidation is natural and will eventually happen to any mattress, especially memory foam ones. However, you can slow oxidation down by keeping your mattress away from moisture and out of direct sunlight.

Why does foam turn yellow when it ages? All foam oxidizes and will turn yellow when it ages. Just like when a penny becomes darker over time. This is a completely natural process that the foam goes through and in no way impairs the effectiveness of the foam.

Polyurethane foam will yellow if exposed to UV light. The yellowing is caused by an oxidation reaction in the backbone of the polymer. Since it is the polymer itself which is being oxidized, the yellow color cannot be extracted and the foam will ultimately degrade over time.
Since oxidation occurs from the foam reacting with oxygen for a long period of time, the foam changes color due to age, and in some cases, the material the toppers are made with.

Mist the stain with some cold water to dampen it. Mix 1 tablespoon 3% hydrogen peroxide with 3 tablespoons of baking soda in a spray bottle. Spray your DIY solution over the entire stain, and scrub it lightly with a soft bristle scrub brush until the stain fades away. Repeat as necessary.
