There are a few things to consider when selecting oil for teak indoor furniture. The first is the type of finish that you desire. If you want a natural look, then an oil with no added color is best. If you prefer a richer, more golden hue, then an oil with added pigment is a good choice. The second thing to consider is the level of protection that you need. If your furniture will be in a high traffic area, or if it is particularly susceptible to scratches and wear, then a hardwearing oil like tung oil is a good option. For less wear and tear, something like Danish oil will suffice. Thirdly, think about how often you want to re-apply the oil. Some oils need to be reapplied regularly (every few months), while others only need to be done once or twice a year. With all these factors in mind, here are some specific recommendations for teak indoor furniture:
For a natural look: Teak Oil
For added protection: Tung Oil
For less frequent maintenance: Danish Oil
