Use acetone when you need a fast-flashing, water-miscible solvent that strips resins, adhesives and uncured coatings and leaves no residue; use mineral spirits when you need a slow-evaporating, oil-loving hydrocarbon for degreasing, thinning oil-based paints and cleaning without attacking finishes. Acetone flashes at 0 °F and is EPA VOC-exempt; mineral spirits flash at 102–110 °F and count as a VOC.
The two are not interchangeable. Acetone (CAS 67-64-1) is a polar ketone. Mineral spirits (CAS 8052-41-3, also sold as Stoddard solvent) are a refined petroleum distillate of mostly C10-and-heavier hydrocarbons. That difference drives every other line in this comparison: solvency, evaporation, fire class, VOC status and shipping.

Which solvent cleans and dissolves better?
It depends on what you are removing. Acetone is polar, so it dissolves many resins, lacquers, adhesives, inks and uncured polyester and epoxy residues, and it mixes completely with water. Mineral spirits are non-polar, so they dissolve oils, greases, waxes and oil-based paints and leave most cured finishes alone.
- Grease and shop soil on metal parts: mineral spirits. Slow evaporation gives the solvent time to work on heavy soils.
- Adhesive, resin and uncured coating cleanup: acetone.
- Thinning oil-based paints, varnishes and stains: mineral spirits.
- Final wipe before bonding or painting: acetone, because it flashes off fast and leaves no oily film.
- Cleaning near plastics or painted surfaces: mineral spirits. Acetone softens or dissolves many plastics and finishes — test first.
Which evaporates faster?
Acetone, by a wide margin. Acetone boils at 133 °F; mineral spirits start boiling at 309 °F, roughly 175 °F higher. Acetone flashes off a wiped surface in seconds, which is why it suits final wipes and fast cleanup. Mineral spirits stay wet much longer, which suits soaking, brushing and parts-washer duty, and gives paints a longer working time.
Which is safer to store and handle?
Mineral spirits carry the lower fire hazard; acetone carries the lower exposure limit risk. Acetone’s 0 °F flash point makes it a Class IB flammable liquid: vapors can ignite at any normal room temperature. Mineral spirits, at 102–110 °F, are a Class II combustible liquid. On exposure, OSHA allows 1,000 ppm of acetone over an 8-hour shift against 500 ppm for Stoddard solvent. NIOSH lists aspiration chemical pneumonitis and kidney effects in animals for Stoddard solvent; for acetone it lists eye, nose and throat irritation, headache, dizziness and central nervous system depression. Both are incompatible with strong oxidizers.
Storage details for acetone are in how to store acetone safely.
Which one counts as a VOC?
Mineral spirits do; acetone does not. EPA lists acetone among the compounds with negligible photochemical reactivity excluded from the federal VOC definition in 40 CFR 51.100(s)(1). Mineral spirits are not on that list, so they count toward VOC limits in coatings and cleaning-solvent rules. Switching a cleaning step from mineral spirits to acetone can cut reported VOC, but it trades a combustible liquid for a Class IB flammable one. State and local air rules can be stricter than the federal definition. The full regulatory picture is in is acetone a VOC?
How do they ship?
Acetone ships as UN1090, a DOT Class 3 flammable liquid. Mineral spirits typically ship as UN1268, petroleum distillates n.o.s. Because their flash point is at or above 100 °F (38 °C), DOT allows a material like mineral spirits that meets no other hazard class to be reclassed as a combustible liquid for ground transport under 49 CFR 173.150(f), which removes most hazmat requirements for non-bulk packages. Confirm the classification on the SDS for your type. Background on classes and packing groups is in DOT hazmat classes for solvents.
Can you substitute or blend them?
Not as a drop-in. Acetone in place of mineral spirits evaporates before it can work on heavy grease and can damage finishes. Mineral spirits in place of acetone leave an oily film and will not remove most adhesives or resins. Adding acetone to mineral spirits pulls the blend’s flash point down toward acetone’s; treat any such blend as a flammable liquid unless a tested SDS says otherwise.

Frequently asked questions
Is acetone the same as mineral spirits?
No. Acetone is a single compound, a ketone with CAS 67-64-1. Mineral spirits are a blend of petroleum hydrocarbons, CAS 8052-41-3. Acetone mixes with water, evaporates in seconds and flashes at 0 °F. Mineral spirits do not mix with water, evaporate slowly and flash at 102–110 °F.
Can I use acetone instead of mineral spirits?
Only for some jobs. Acetone works for adhesive, resin and uncured coating cleanup and final wipes. It is a poor substitute for degreasing heavy soils or thinning oil-based paint, it evaporates too fast, and it can soften plastics and finishes. It also raises the fire hazard from a Class II combustible to a Class IB flammable liquid.
Is acetone stronger than mineral spirits?
Acetone is the more aggressive solvent on resins, adhesives, lacquers and many plastics. Mineral spirits are more effective on oils, greases and waxes. Neither is stronger across the board; match the solvent to the soil.
Which is better for low-VOC compliance?
Acetone. It is excluded from the federal VOC definition in 40 CFR 51.100(s)(1); mineral spirits are not. Check state and local air district rules, which can be stricter.
Where can I buy acetone and mineral spirits in bulk?
RightPath Industries supplies both acetone and mineral spirits in pails, drums and totes from three U.S. warehouses, with lot control and same-day quotes. Other options include Univar Solutions, Brenntag North America and, for consumer-size cans, paint and hardware distributors.
