Mix a degreaser concentrate with water at the label’s stated ratio, apply, scrub, then rinse clean.
Making a degreaser cleaner isn’t about inventing a formula from scratch — it’s about diluting a commercial concentrate correctly and applying it the right way for the job. Most degreasers arrive as concentrated liquids that need water added before use, and the ratio you choose determines whether you’re doing light maintenance or heavy grease removal. The single most important step happens before you open the bottle: reading the product label or Safety Data Sheet (SDS) for that specific product’s dilution ratio, surface compatibility, and personal protection requirements. Formulas vary widely between brands, so the label isn’t a suggestion — it’s the instruction manual.
Selecting the Right Dilution Ratio
Commercial degreaser concentrates typically specify a range of mixing ratios depending on how heavy the soil load is. The right ratio for your job depends on the product and the surface. As a general pattern, lighter cleaning jobs like wiping down counters or mopping floors call for more water (often 1 part cleaner to 40 parts water), while heavy-duty power washing jobs call for a stronger mix (1 part cleaner to 5–10 parts water).
Product labels give the exact numbers for their own formulas. These numbers are product-specific, but they show the range you’ll typically encounter.
How to Apply a Degreaser Cleaner
Apply the mixed degreaser to the greasy surface, let it work briefly, then scrub or agitate before rinsing or wiping clean. For light grease, a simple spray-and-wipe approach works. For heavy contamination, soak or immerse the part, brush it to break up the grease, then rinse thoroughly — with a pressure washer if needed.
One effective approach for tough jobs is to scrape or wipe away loose grime first, then apply the diluted degreaser, scrub, and wipe clean with a fresh cloth. Reusing a contaminated cloth just spreads the grease back onto the surface.

Safety and Surface Compatibility
Heavy-duty degreasers are often non-flammable and VOC-free, but that doesn’t make them harmless to every surface. EPA-related material regarding these products warns to use caution on plastics and paints, which can be damaged by aggressive formulas. Nuvera’s plant-based degreaser explicitly states it’s not recommended for wood or varnished surfaces and should be spot-tested on painted surfaces before full application.
The SDS for your specific product is the authoritative source for three things: the correct dilution ratio, the required personal protective equipment (gloves, eye protection), and first aid and disposal instructions. Checking it before mixing takes two minutes and prevents both damaged surfaces and personal injury.
| Degreaser Product | Light Cleaning | Heavy Cleaning |
|---|---|---|
| Heiser Cleaner Degreaser | 1:40+ (brushing/mopping) | 1:5–10 (power washing) |
| ShareCorp Formula 10 | 1:15 | 1:7 |
| Safety-Kleen Heavy Duty | 1:50 | 1:15 (heavy, CA); 1:4 (non-CA) |
Common Mistakes to Avoid
The most frequent errors when using a degreaser are using the wrong dilution for the soil level, letting the product dry on the surface, skipping agitation on stubborn grease, and not removing loose grime beforehand. Using too weak a mix on heavy grease means multiple passes and wasted time; using too strong a mix on a light job risks surface damage. Letting the product dry can leave residue behind, and agitation — whether brushing or scrubbing — is what physically breaks the grease bond that chemistry alone can’t always beat.
Simple Green’s Industrial Cleaner & Degreaser illustrates another common issue: many formulas contain a blend of surfactants and solvents that are effective but require proper rinsing to avoid leaving a film, especially on food-contact surfaces.

FAQs
Can I use household dish soap instead of a degreaser?
Dish soap works on light grease but is generally too mild for heavy engine or machinery grime. Commercial degreasers contain solvents and surfactants formulated to cut through baked-on or industrial-strength grease. For everyday kitchen cleaning, dish soap is often sufficient; for garage or workshop jobs, a dedicated degreaser is worth the cost.
Is it safe to mix degreaser with bleach or other cleaners?
No. Mixing degreasers with bleach or acidic cleaners can release toxic or irritating fumes. Some degreasers contain alkaline ingredients that react dangerously with bleach. Use degreasers only as directed, and never combine them with other cleaning chemicals. If you need to switch products, rinse the surface thoroughly and allow it to dry first.
Do degreasers damage car paint or automotive finishes?
Yes, many heavy-duty degreasers can strip wax and damage automotive paint if left on too long or used at full strength. Aggressive solvents soften clear coats and can etch the surface. If you’re using a degreaser on a vehicle, dilute it per the label’s lightest recommended ratio, rinse promptly, and avoid letting it dry. Spot-testing an inconspicuous area first is always wise.
