Tea tree oil
Teak oil is commonly used on hardwoods, such as mahogany or teak, and is preferred for forests that are regularly exposed to moisture, as in many marine crafts or hardwood floors. Like any oil resistance, some oil products give a deep hue to the natural color of the wood.
Tungolja
Heavy oil is similar to teak oil in application. Many people use the heavy oil for its ‘wet’ appearance when it is dry. Stone masons often apply light oil boats to masonry for kitchens or bathrooms, as the oil is very moisture resistant. Heavy oil dries in a lighter shade than teak oil, which gives the wood a slightly golden hue.
Oil for bass
Base bodies are usually made of ash, age or maple. The body forest is finished with garments of polyurethane or satin that protect the body and preserve the wood. Basses made with exotic wooden bodies (bubinga, wenge, zebrawood, purpleheart and korina) are porous, and the hardwood absorbs moisture. For bass guitars, moisture can damage internal electronic components as well as the hot neck.
Tung vs Teak
Heavy oil is preferred by those players who like to see the natural grains of the wood shine through. Heavy oil bases are called ‘blonde’ or ‘honey blonde’ and are known to be a little more water resistant than teak.
Warning
Most commercially available oils contain other substances besides the oil to keep costs down, as 100 percent teak or heavy oil is quite expensive to obtain. These oils are said to contain paints and minerals that can dilute the oil’s effects or water resistant properties. Like other musicians, bass players are a demanding group and require most of their instruments. Therefore, there is no shortage of TLC to maintain its base in top games, from settings to regular string changes. For some players, especially those whose bases are made of untreated (usually exotic) woods, oil or wax is used to seal the pores of the wood from external moisture that can cause twisting. Two common choices are teak oil and heavy oil.
