First go to the Channels panel and select the Blue channel by holding Ctrl/Cmd while clicking on the thumbnail in the channel panel:



You should see a marquee appear on the image.

Now on the Layers Panel click the icon at the bottom that looks like a black and white cookie:



That's for Adjustment Layers. Either Curves or Levels will work. I prefer Curves, so hit Curves

On the left side hit the eye dropper with the white liquid in it that looks like an eye dropper with white liquid in it:



Then click on the yellow.

The reason for the mask is to preserve as much of the color in the rest of the image as possible. If you want to preserve even more you could've duplicated the blue channel and then used Levels on that channel to darken it a bit before doing the curves adjustment on the entire image:



Can then move the White Point in a little to get rid of the remaining texture.
