Mineral spirits are a petroleum-based solvent commonly used as a paint thinner and cleaner. They dissolve oil-based paints, stains, varnish residue, tar, and greasy buildup, making them handy for prepping surfaces and cleaning tools.

• Typical uses: Thinning oil-based paint, cleaning paint brushes and rollers, degreasing metal parts, removing sticky residue.
• Options you’ll see: Odorless or low-odor mineral spirits, low-VOC formulas, and artist-friendly sizes for studio work.
• Safety basics: Work in a well-ventilated area, keep away from heat/flames, and follow the product label.

Walmart carries quarts, gallons, and smaller artist sizes, so you can choose what fits the job. Many items are available for pickup or delivery for added convenience.

They’re different solvents with different strengths. Understanding those differences helps you pick the right cleaner for the task.

• Mineral spirits: A petroleum-derived, non-polar solvent that loosens oil-based paint, varnish residue, grease, and tar. It’s commonly used as a paint thinner for oil-based coatings and for cleaning brushes and tools.
• Rubbing alcohol (isopropyl alcohol): A polar solvent that evaporates quickly and is suited to light cleaning tasks like removing fingerprints, some inks, and residues on hard, non-porous surfaces. It’s not typically used to thin oil-based paint.

Whichever you choose, ventilate the area, keep away from open flames, and follow the product label. Avoid mixing solvents and always spot-test on a small, hidden area first.

Used rags and paper towels with mineral spirits can pose a fire risk if handled improperly. Consider these steps to reduce risk and follow local rules.

1. Don’t toss while wet: Avoid putting solvent-wet rags straight into the trash.
2. Dry safely: Lay rags flat to dry outdoors on a nonflammable surface, away from heat, flames, and direct sun, until fully dry.
3. Contain if needed: Alternatively, place used rags in a metal container filled with water and a bit of detergent, then seal until you can dispose of them properly.
4. Follow local guidance: Liquids and heavily saturated items may need to go to a household hazardous waste facility. Never pour solvents down drains or into the ground.

Always check your municipality’s disposal guidelines and follow the product label.

Mineral spirits can be too harsh for some materials and finishes. When in doubt, spot-test first and follow label directions.

• Water-based finishes and latex paint: It can dull or damage these coatings.
• Some plastics and rubber: Certain plastics (like acrylic or polycarbonate) and natural rubber can haze, soften, or swell.
• Delicate furniture finishes: Shellac, lacquer, and certain clear coats may be affected.
• Fabrics, leather, and skin: Not intended for porous materials or personal use.

For sensitive surfaces, consider a milder cleaner designed for that material. If you choose to proceed, use a small hidden test area first, wipe residue with a clean cloth, and ventilate the space.

Match the solvent to your task and workspace so you get effective results with fewer hassles.

• Job type: For thinning oil-based paint or cleaning brushes, standard mineral spirits work well. For art studios and indoor cleanup, odorless or low-odor options may be more comfortable.
• Ventilation and sensitivity: If you’re working indoors or are odor-sensitive, consider low-odor or low-VOC formulas and ensure good airflow.
• Size: Small bottles suit art projects and touch-ups; quarts and gallons fit larger painting or degreasing jobs.
• Compatibility: Always check the coating or manufacturer guidelines to confirm the solvent is appropriate.

Walmart offers multiple sizes and formulas, with many items available for store pickup or delivery.
