Solvent damaged finish on stock - ideas to fix it?

I was cleaning the barrel of by 1949's Lee Enfield with [this product](https://www.boretech.com/products/eliminator-bore-cleaner) and some dripped on the wood stock. There's a streak and i'm not exactly sure if it stripped the finish or stained the wood.

I tried cleaning with a rag and water and then soapy water with no improvement. I also tried rubbing some tung oil since I thought that might've just been removed by the solvent, also with no improvement.

Here is a pic of the streak: https://imgur.io/a/hgyxT0Q

I know it's not crazy but I'd like to preserve the rifle as much as possible. Obviously will be more careful cleaning next time. Never had this happen before. Does anyone have any ideas or tips on how to fix this?
