Hi Guys,
First time poster and very new to woodworking. I've been making a stool in black walnut and read that for a good finish, I should pre-raise the grain by wetting with water and then sanding before any finish. I did that, and though the result is incredibly smooth, it turned the walnut a chalky white. I initially believed it to be water staining, but it appears to be sanding dust lodged in the pores of the walnut.

The leg on the left has been wet-sanded as described above, but the one on the right is still unsanded.
In order to remove the dust, I've dried Denatured Alcohol, a stiff brush, and an air-compressor, but nothing seems to touch it. I plan on finishing with Polyurethane thinned with Mineral Spirits. Will the finish restore the color of the walnut? Should I try a stain? Should I try a tack cloth. Any advice would be greatly appreciated.
Thank you,
Scott Sonnenberg
