  • Results not as consistent or controllable as commercial products

Overall, household substitutes should only be used sparingly and cautiously until a proper mineral spirit alternative can be obtained. The risks likely outweigh the small convenience benefit.

Specialized Products

Beyond household items, there are now specialty products designed as direct substitutes for mineral spirits:

The Real Milk Paint Company – Natural Citrus Solvent

The Real Milk Paint Company produces plant-based, eco-friendly finishes and strippers. Their Natural Citrus Solvent is made from USDA certified organic orange oil and designed to replace mineral spirits directly.


  • Bio-based formula from sustainable sources
  • Natural citrus scent
  • Low VOC/non-toxic
  • Effective cleaner and degreaser
  • Can be used for paint thinning and brush cleaning


  • More expensive than mineral spirits
  • May need multiple applications for some jobs
  • Not as effective on heavy grease or grime

Klean-Strip Green – Odorless Mineral Spirits

Klean-Strip Green is a mineral spirit substitute made from 65% more renewable resources. It has an odorless formula for improved air quality.


  • Low odor improves indoor air quality
  • High flash point for safer handling

How Do Murphy Oil Soap and Krud Kutter Perform In Comparison to Traditional Mineral Spirits?

Murphy Oil Soap and Krud Kutter are both effective cleaners, but fall short as full substitutes for the performance of mineral spirits:

  • Neither match the ability of mineral spirits to thin oil-based paints effectively. Paint thinning is one of the primary uses of mineral spirits.
  • They have limited power to remove heavy grease and grime. Mineral spirits are valued for strong degreasing abilities.
  • Krud Kutter requires heavy dilution to approach mineral spirits safety levels. Undiluted it is much harsher.
  • Murphy Oil Soap leaves more residue and is not designed as a multi-purpose solvent/cleaner like mineral spirits.
  • Soap and water can damage paint brushes over time while mineral spirits safely clean them.

While Murphy Oil Soap and Krud Kutter have benefits like plant-based ingredients, they cannot fully replace the versatility and performance of mineral spirits across multiple applications.


When considering alternatives to traditional mineral spirits, there are now many effective and eco-friendly options to explore.

Top commercial choices like AcraStrip and Polychem offer similar performance and better environmental profiles. For one-off uses, household products like denatured alcohol can work in a pinch but require caution. Specialty plant-based solvents like citrus thinners provide a direct mineral spirits substitute for paint thinning and brush cleaning with minimal indoor air impact.
