Mineral spirits, also known as white spirits or mineral turpentine, are petroleum-derived clear liquids used in various household tasks, including cleaning. These organic solvents are insoluble in water and are used for extraction, cleaning, degreasing, and various applications. In Western Europe, 60% of white spirit consumption is used in paints, lacquers, and varnishes. Mineral spirits also clean paint brushes, auto parts, and tools and remove adhesive residue from non-porous surfaces. They are popular in the industry for cleaning and degreasing machine tools and parts and are commonly used in households to clean paint brushes and other tools.
Are Mineral Spirits for Cleaning Toxic?
Mineral spirits are mainly classed as an irritant. They have fairly low acute toxicity but can lead to central nervous system depression, resulting in decreased coordination and slowed reactions. Exposure to very high concentrations can lead to general narcotic effects like drowsiness, dizziness, nausea, and even unconsciousness.
Chemical Composition: Mineral spirits are a mixture of hydrocarbons, and their toxicity depends on the type and grade. Odorless mineral spirits (OMS) have been refined to remove the more toxic aromatic compounds and are recommended for applications like oil painting.
Potential Health Risks: Prolonged or repeated skin exposure can result in severe irritant dermatitis. Continuous exposure to an average concentration of 240 mg/m3 for more than 13 years can lead to chronic central nervous system effects, including memory impairment, poor concentration, increased irritability, and even chronic toxic encephalopathy (CTE) among house painters.
Safety Measures: Handling mineral spirits carefully, following safety guidelines and using proper protective equipment. The Occupational Safety and Health Administration (OSHA) has set legal limits for exposure in the workplace, and it is crucial to adhere to these regulations to minimize risks.
Environmental Considerations: Although moderately toxic to aquatic organisms, mineral spirits are unlikely to present significant environmental hazards. However, they should not be purposely poured down the sink or freshwater drain.
How to Utilize Mineral Spirits for Cleaning Various Surfaces?
Mineral spirits are not just for thinning paint; they’re versatile cleaners that can make short work of some of the toughest home, yard, and garage messes.
1. Clean Paintbrushes and Other Painting Tools: After painting, dip the brush or roller in mineral spirits to remove oil-based paint. If the paint has dried, use a paintbrush comb to loosen it up. Continue dipping until the paint is gone, blot away excess solvent, and let it air dry.
2. Degrease Automotive Parts: Auto enthusiasts can use mineral spirits to clean dirt-and-oil buildup on car engines and bicycle chains. Submerge small parts in a container of mineral spirits or wipe larger parts with a mineral-spirits-soaked rag. Wipe away excess solvent and relubricate with fresh oil as necessary.
3. Remove Paint Spills: If you spill oil-based paint on a hard floor surface, dampen a clean rag with mineral spirits and wipe away the paint before it dries. Please test a small spot first to ensure it doesn’t damage the floor’s finish.
4. Wipe Away Sticky Price Tags Residue: Pour mineral spirits onto a rag or paper towel and wipe the glue residue off the glass, porcelain, or glazed clay surfaces. Wash the dish in warm, soapy water afterward.
5. Clean Scuff Marks off Your Floors: Dab at black scuff marks on linoleum, wood, laminate, tile, and vinyl floors with a mineral-spirits dampened paper towel or rag. Wipe away the solvent residue with a damp rag and a few drops of dish soap.
6. Clean and Restore Wood Furniture: If unpainted wooden furniture looks dull, use mineral spirits to restore its shine. Dampen a clean rag with the solvent and buff away the grime in circular motions. Buff the wood until the shine is restored, followed by a protective wax coating if desired.
7. Get Garden Tools Shiny: Remove sap from garden tools by submerging them in mineral spirits or wiping them with a mineral spirits-soaked cloth. Once the sap is gone, use a dry cloth to remove solvent residue.
Safety Considerations: Mineral spirits are flammable and toxic to some degree, so they should always be used with excellent ventilation, kept away from skin and eyes, and disposed of properly at a hazardous waste recycling center.
Is It Safe to Use Mineral Spirits for Cleaning Indoors?
Mineral spirits are highly effective but must be used cautiously, especially indoors. Here’s what you need to know about indoor safety:
1. Ventilation: Always use mineral spirits in a well-ventilated area. The fumes can cause eye and throat burning, coughing, headache, dizziness, and confusion with prolonged exposure.
2. Protective Measures: Wear goggles and chemical-resistant gloves when handling mineral spirits. Keep them away from any source of sparks or open flames.
3. Guidelines for Indoor Use: Mineral spirits are more refined than paint thinner, reducing odor and toxicity. You can find odor-free mineral spirits, which are less toxic and have a slight smell. These are the formula of choice for most indoor applications.
4. Disposal: Dispose of mineral spirits properly at a hazardous waste recycling center. Improper disposal can lead to environmental harm.
5. Cost Considerations: Mineral spirits typically cost around $12 per quart, while odor-free mineral spirits are about $15 per quart. Though pricier, further refinement makes them less toxic and more suitable for indoor use.
Using Mineral Spirits for Cleaning Before Painting
Preparing surfaces for painting is a critical step in achieving a flawless finish. Mineral spirits can be a valuable ally in this process, especially when dealing with surfaces previously painted or contaminated with grease or dirt.
