Worth it for contractors doing sensitive indoor work. The 120°F flash point versus 105°F for standard mineral spirits gives you a real safety margin when working in occupied buildings. 100% odorless formulation (highly refined) means you can paint a hospital room without clearing the floor.
Skip it if you’re just cleaning brushes in a ventilated shop. Regular mineral spirits cost less and work fine when odor doesn’t matter.
Technical Performance That Matters
This isn’t “low odor” marketing nonsense — it’s actually odorless. The refinement process strips out the aromatic solvents that make standard thinners stink. Free of objectionable aromatic solvents and low toxicity, making it suitable for sensitive environments such as hospitals and nursing homes.
The slow evaporation rate changes how you work. Slow evaporation rate to reduce overspray and fumes means less waste when spraying and more open time for blending. You’re not racing the clock like with fast-evaporating thinners.

It evaporates cleanly without residual odor or residue, which beats regular thinners that leave that petroleum smell for days.
Why Montana Contractors Need This
Montana winters force painting indoors for six months. Buildings are buttoned up tight for energy efficiency — no open windows, minimal air exchange. Standard thinners turn that sealed space into a chemical chamber.
The higher flash point (120°F) matters when you’re working in shops where propane heaters run constantly. That 15-degree safety margin between this and regular mineral spirits isn’t just numbers — it’s the difference between safe storage and a fire code violation.
School districts from Billings to Missoula have gotten strict about VOCs and odors. This thinner lets you bid those jobs without special ventilation equipment. Common use cases include thinning oil-based paints, primers, stains, varnishes, and general-purpose degreasing, especially in environments where low odor and safety are priorities.
Compatible Materials
Works with oil-based paints, enamels, stains, varnishes, clear coats, metal, wood, masonry, concrete, brick. Don’t use it with latex or water-based coatings — wrong chemistry entirely.
Not intended as a paint remover for cured coatings. This is for thinning and cleanup, not stripping.
Real-World Performance
Dick Blick customers rate it 4.8/5 across 3,181 reviews, with Walmart customers also giving it 4.8/5. Those aren’t hobbyist numbers — that’s contractors using it daily.
100% mineral spirits composition means consistent performance batch to batch. No mystery blends that vary by production run.
The slow evaporation isn’t just about reducing fumes. It gives you working time to maintain a wet edge on large surfaces. Try that with acetone or lacquer thinner and you’ll be chasing lap marks all day.
Regional Restrictions and Returns
Not for sale in California due to VOC content exceeding CARB/SCAQMD limits. Montana doesn’t have those restrictions yet, but it’s worth knowing if you’re working across state lines.
Dick Blick offers 365-day returns, Walmart and Menards give you 90 days, while Amazon and DK Hardware limit returns to 30 days. Manufacturer liability is typically limited to product replacement or refund of the purchase price for defective product.
Frequently Asked Questions
Q: Is this really odorless or just “low odor” like other brands claim?
A: It’s 100% odorless from highly refined solvents. Completely odorless and free of aromatic solvents — not marketing speak. You can use this in a closed room without anyone knowing you’re working with solvents.
Q: How does the slow evaporation rate affect spray painting?
A: The slow evaporation rate reduces overspray. You get better transfer efficiency and less material floating around as mist. It also means you need to allow more flash time between coats compared to fast-evaporating thinners.
Q: Can this replace turpentine for all applications?
A: For thinning and cleanup, yes. It’s effective at dissolving grease, grime, and oil from various surfaces. But turpentine has specific uses in fine art and some specialty finishes where the resin content matters. This is pure mineral spirits — no pine resin properties.
Q: What’s the actual weight difference I’m dealing with?
A: Each gallon weighs 7.17-7.25 lbs with a specific gravity of 0.762. That’s lighter than water (8.34 lbs/gal) but heavier than some fast-evaporating solvents. The density affects how it mixes — add it slowly while stirring.
Q: Does the higher flash point mean it’s safer to store?
A: At 120°F flash point with Class II Combustible rating, it’s safer than standard mineral spirits but still requires proper storage. Keep it away from heat sources, store in original containers, and follow fire code requirements for flammable liquid storage.
