Neither is universally "better"; it depends entirely on your project. Mineral spirits is better for gentle cleaning and working with oil-based paints, while acetone is better for aggressive stripping, removing glue, and fast-drying surface prep.
Neither is strictly "better" than the other; they are fundamentally different solvents designed for different tasks. Acetone is aggressive, fast-evaporating, and ideal for heavy-duty stripping, while mineral spirits (paint thinner) is milder, oil-based, and safer for wood and plastics.
Methyl acetate is a widely used acetone alternative due to its strong solvency, lower toxicity, and reduced flammability.
Yes, but you must never throw them away wet or crumpled. Mineral spirits evaporate quickly and release fumes that can build up heat and spontaneously combust in a confined space like a trash bin.
Mineral spirits will not effectively remove nail polish. Designed to thin oil-based paints and clean surfaces, it lacks the chemical strength to break down nail lacquers. Using it can leave an oily residue and expose your skin to unnecessary toxicity.
The healthiest way to remove nail polish without stripping your nails is to use a nourishing acetone-free remover and the press-and-slide method. Acetone-free removers use gentler solvents and moisturizing ingredients to protect your nail beds, while the press-and-slide technique prevents you from scrubbing away your natural nail layers.
The best substitutes for mineral spirits depend on your task. For thinning oil-based paints, use standard paint thinner or Crown Mineral Spirits Substitute. For cleaning brushes and degreasing, use Klean Strip Green Odorless Mineral Spirits Substitute or food-grade citrus solvents.
You generally do not need to wash off mineral spirits with soap and water, but you must allow them to evaporate completely—usually 1–2 hours—before painting, staining, or sealing. Mineral spirits are volatile and typically leave no residue, making them excellent for cleaning surfaces or thinning oil-based paints.
Rags with only mineral spirits will not spontaneously combust. Read the second paragraph of this linkJust let them dry and reuse them. I've never used Odies oil but I would not take chances. I just hang oily rags until they are dry and then throw them in the trash.
No, mineral spirits do not go bad. If stored in an airtight container, they have an indefinite shelf life and will maintain their effectiveness for thinning paint and cleaning. However, the liquid can become contaminated or lose volume if exposed to air.
A solvent very similar to acetone is methyl acetate. Both behave similarly, are flammable, and may cause irritation. However, comparing against acetone, methyl acetate is overall: Less irritating to the human body.
Acetone Soaking
This is the most common method used in salons. Nail technicians buff the top coat of the gel polish to break the seal, then soak your nails in pure acetone for 10-15 minutes. The acetone dissolves the gel, allowing for easy removal.
Acetone should not be used on 1-part paints or varnish coatings, and it is very important to test or know compatibility on plastics or any other materials (beyond wood, metal, epoxy, and polyester resin). Acetone should never be used on clear windows, lenses, or clear plastics.
Use mineral spirits as a solvent to thin oil-based paints, varnishes, and stains, clean up brushes and rollers, degrease metal tools, and remove sticky residues or sap. It is also widely used by woodworkers to wipe away sanding dust and preview the final wood grain.
Mineral spirits are a petroleum-derived solvent. Depending on your region and the specific formulation, the most common alternate names include:
Mineral spirits act as a potent solvent that thins oil-based paints, varnishes, and stains, and dissolves wet or uncured paint. It is a highly refined petroleum derivative often used to alter paint consistency, clean brushes, or strip away fresh paint splatters.
ArroChem's Mineral Spirits Rule 66 – Solvent 140, also known as White Spirits, is a hydrocarbon-based solvent derived from petroleum distillation that is hydrotreated to reduce aromatics and olefins. It is a widely used industrial solvent with excellent dissolving capabilities and a relatively high flash point.
Mineral spirits are hydrocarbons commonly found in wood stains, paints and paint thinners. Direct contact with mineral spirits causes skin burns, irritation and even necrosis. Nitrile gloves offer protection for safe handling of mineral spirit concentrations of up to 100 percent.
Yes, rags soaked with mineral spirits are highly combustible. While mineral spirits evaporate rather than chemically generating heat to self-ignite like boiled linseed oil, bunched-up rags act as a trap for trapped fumes and vapor. If exposed to a heat source, spark, or static, they can catch fire.
You generally do not need to wash off mineral spirits with soap and water, but you must allow them to evaporate completely—usually 1–2 hours—before painting, staining, or sealing. Mineral spirits are volatile and typically leave no residue, making them excellent for cleaning surfaces or thinning oil-based paints.
While acetone will aggressively strip paint from a wide variety of surfaces, though, mineral spirits is really only effective at cleaning up fresh paint. It can clean brushes and other tools after you finish a project, but once the paint dries, mineral spirits is mostly ineffective.
Let your surface dry for 30 to 60 minutes before painting. The mineral spirits must be completely evaporated. Wait times vary based on ventilation, room temperature, and the amount applied. Wait at least 24 hours if you are applying a water-based paint, as any lingering solvent can ruin the finish.
After vacuuming the surface with and against the grain, we recommend tacking it. This can be accomplished by using a mop or lint-free rag or micro-fiber mop dampened with mineral spirits (paint thinner)1 which will attract any remaining dust and dirt.
Yes, but only if you use a solvent-resistant spray bottle (such as one made of HDPE plastic with Viton or PTFE seals) and never a standard household plastic bottle, which the mineral spirits will quickly degrade.
