It absorbs oxygen from the air faster and more efficiently than linseed oil. In varnish it passes oxygen from the air to the oleo-resinous compound.
Lacquer finishes are very difficult to remove, but if you follow these steps, you can easily do it. You need to use a solvent, such as acetone or turpentine. First, clean your surface thoroughly by wiping it down with soap and water. Then, apply some thin layers of lacquer thinner over the entire surface.

Mineral spirits will soften a natural varnish finish so that surface material can be wiped off. A sanding sponge is a good rubbing tool to remove the softened varnish because it conforms to the contours of the wood and does not leave metal particles behind.
Mineral turpentine is considered to have more solvency than methylated spirits. This means that it has the greater ability to dissolve with other solvents. Turpentine is considered to be more dangerous than methylated spirits as it is highly flammable and can irritate the skin and eyes.

The liquid doesn't make the wood swell, thus damaging it or changing its size, but rather wipes off any stains, especially oil. It also dries quickly when rubbed over a wooden surface.
Mineral spirits, also called ''white spirits'' (trade names include Varnolene and Texaco spirits), is a petroleum distillate specifically manufactured as a substitute for turpentine.
