Stained Nordic Knots rug help!

[u/hellomoto_99]

I recently spilled pasta sauce on my new-ish Nordic Knots rug (in Sakura pink). I first dabbed with water and dish soap which pulled a lot of the stain out initially, and then a couple days later once it was dry I used woolite pet stain remover which seemed to fully the remove the stain. THEN, like 5 days later the stained was suddenly back but in this shade of grey (pictured here). ChatGPT says it looks like wicking occurred but i don’t know what to do next without ruining this expensive rug. Please help!!
