Since I have never found this information: If untreated, polished teak tables (for the interior) the color is about the same, if you fill the table wet wipes such. The oil penetrates so deep enough to cheer the teak. Who does not like should possibly take the color "natural" (with white pigments). The smell when applying what has mixed of fresh leather jacket with solvents. Definitely not for sensitive people who want to do it in winter in the living room and then have to live with it for a few days. In the summer of continuous airing it will certainly go. Odorless colors have not been invented yet, react to organic solvents such as orange oil, some people sensitive.
