It is used to clean wood and remove old finishes, stains, and dust
Denatured alcohol is a versatile substance with a variety of applications. It is often used to clean wood and remove old finishes, stains, and dust. While it is not chemically distinct from drinking alcohol, it is intentionally laced with poisonous and nausea-inducing additives to make it unfit for consumption. This distinction allows it to be sold without alcohol tax and prevents people from drinking it.
When used for cleaning wood, denatured alcohol is applied undiluted with a lint-free cloth. It is particularly useful for removing the final sanding dust from wood before staining or painting. It dries quickly, allowing for the subsequent application of stain, paint, or other finishes. Denatured alcohol can also be used to check for any imperfections, such as sanding marks, glue spots, or scratches, that may have been missed during the sanding process.
In addition to its cleaning properties, denatured alcohol is an excellent solvent. It can be mixed with shellac, a resin used for finishing and protecting wood, to create a primer that helps the wood absorb the shellac more evenly. This mixture can also be used to clean and refinish porous wood surfaces.
It is important to note that denatured alcohol should be handled with caution. It is considered a hazardous material due to its toxicity, and users are advised to wear protective gloves and work in a dry, well-ventilated area when applying it to wood.
While denatured alcohol is a useful product for cleaning and refinishing wood, it may not be suitable for all situations. For example, if the existing finish on the wood is shellac, using alcohol for cleaning is not recommended as it can dissolve the shellac. In such cases, alternative products like mineral spirits may be more appropriate.
