Mineral Spirits
Mineral spirits, also known as Stoddard solvent, petroleum spirit, or white spirit, are a petroleum-based single solvent that are sometimes used as a substitute for turpentine in thinning paint and cleaning surfaces and paintbrushes. It is also used for thinning both interior and exterior oil-based varnishes, oil-based paint and can be used in wiping wood stains.
There are many different kinds of mineral spirits so they are divided into types and classes. One type, called Type II, is odorless and fairly common as paint thinner. Various chemicals are used in its production so it is not entirely safe. However, although it is still hazardous, mineral spirits are considered one of the safer solvents for finishing and refinishing furniture.
