Whether you're cleaning up an engine block, a grill, or the floor of your garage, degreasers are one of the most essential cleaning tools in a DIYer's kit. But choosing the right degreaser can be confusing—especially with so many options on the shelf labeled industrial, heavy-duty, or eco-friendly.
This guide breaks down the major types of degreasers, what they’re made of, and where each one works best, so you can clean smarter and protect your surfaces.
1. What Is a Degreaser?
Degreasers are cleaning agents designed to remove built-up grease, oil, fuel residue, and grime from surfaces. They work by breaking down oily substances so they can be wiped or rinsed away.
2. Solvent-Based Degreasers
These are powerful cleaners that dissolve grease on contact. They’re typically petroleum-based and ideal for heavy-duty jobs like cleaning engine components, chains, or machinery.
Note: These often contain volatile organic compounds (VOCs) and may require ventilation and gloves during use.
3. Water-Based Degreasers
These degreasers use surfactants and water to break up grease and grime. They’re generally safer to use indoors and are less likely to damage paint, plastic, or sensitive surfaces.
4. Bio-Based or Eco-Friendly Degreasers
Bio-based degreasers are derived from natural sources like citrus, soy, or plant oils. While they may not be as fast-acting as solvents, they’re non-toxic, biodegradable, and safe for regular home use.

5. How to Apply Degreasers Safely
- Always test on a small, hidden area first
- Wear gloves and eye protection, especially with solvent types
- Apply to a cool surface (never hot or running engines)
- Allow time to soak before scrubbing or rinsing
- Dispose of runoff properly—especially for petroleum-based products
6. Choosing the Right One
Match the degreaser to the mess. For baked-on grease under your car, go solvent. For cleaning hand tools or surfaces in your kitchen or garage, water-based or bio-degreasers are often enough.
If you only keep one in the shop, opt for a concentrated water-based degreaser that can be diluted for light jobs or used full-strength when needed.
Conclusion
Degreasers make tough cleaning jobs easier—but only if you choose the right type. By understanding the strengths and limitations of solvent, water-based, and bio-based options, you can tackle greasy messes more effectively without damaging your workspace or tools.
Look for degreasers that suit your project needs and safety preferences—and don’t forget to follow usage guidelines for best results.
7. Bonus Tip: Store Degreasers Correctly
Keep degreasers in a cool, dry place away from direct sunlight or heat sources. Make sure lids are tightly closed to prevent spills or evaporation. Label each container clearly, especially if you’re working with multiple types or refilling smaller bottles.
