Owing to the properties of denatured alcohol, one of its most popular applications is solvent for wood. To facilitate identification, the color of denatured alcohol differs from that of pure alcohol.
  • Mineral spirits: Being a by-product of petroleum, mineral spirits possess powerful cleansing effects which is why they are great solvent by all accounts. Depending on the situation, people could use mineral spirits to clean wood, tiles, auto components, paint brushes and so on. Though experts often classify them as irritants, mineral spirits pose less of a threat to the health of people than similar types of solvents. In addition to that, mineral spirits are not as flammable as other petroleum-derived products.

Within moments, the shine should dissolve but if it gets cloudy, mix your denatured alcohol with lacquer thinner. To remove things like paints, fingernail polish, …, you just have to give the surface of the wood a gentle rub.
  • Mineral spirits: Take the same precaution as with denatured alcohol. You could use a paint brush to apply mineral spirits but it’s best to use a piece of lint-free rag. Clean the surface of your project and change to a new rag from time to time. It’s worth pointing out that you should avoid scrubbing with mineral spirits. On average, mineral spirits would dry after fifteen minutes.
