Cabin stairs refinish

After looking at the stairs being always dirty with dust and sand everytime I had to go up and down.

I wanted to fill the grooves to make the stairs look nicer/cleaner.

As a great source of info, did a search here, and found what "Kindered Spirit" did. And was what I had envisioned.

So I took the stairs back home, and gave them a good sanding and cleaning.

Protected them with some Teak Oil.

Then, I covered the full step with painter's tape.
