I have a new customer that used another company's spot remover on a red wine stain. It is a white wool rug. As you can see the stain

turned yellow. It happened a couple months ago according to the customer.

Hoping to get some advice on what if anything can be done to lighten it up or remove the yellowing.

Try to find out about the stain remover that was used. If it was an oxidizer, you need to counteract it with a reducer. If it was a reducer, then you need to counteract with an oxidizer. If it was a strong alkaline, rinse with acid and then use an oxidizer.

Possible reducers - Bridgepoint Coffee Stain Remover about 1/2 normal strength; RedZone Ready diluted with equal amount of distilled water; Red Relief for Wool.

Possible Oxidizers - StainZone diluted with equal amount of distilled water; Stain Magic for Wool; Hydrogen peroxide very fresh 3%;
