My favorite teak oil is Amazons amazing gold. Just refinished mine with the Maquires kit, and I don't like the color as well as the Amazons.
Good cleaning and brightening helps. The Maquires kit did do a good job and I had their oil so that's what I used.
If you can find Amazons Amazing any cleaning/brightening products will work with it fine.
