Real-World Performance Testing
During hands-on garage testing, engine degreaser easily removed stubborn buildup on an oily engine in under 10 minutes. It handled oil grime removal on the engine, suspension, and undercarriage components with just two passes and minimal manual scrubbing.
This tool also excelled as a grease remover for tire cleaning and garage floors. When diluted 10:1, it worked for basic dirt; undiluted, it erased months of caked-on sludge during heavy-duty cleaning.
However, it’s important to note the highly concentrated formula may require gloves and surface pre-testing, especially with painted parts. Despite that, auto detailing jobs were completed faster and with less effort using this device. For more detailed cleaning advice, check our hard water shower filter guide.

This professional strength solution is also highly rated by customers on AutoZone and has positive reviews on Amazon for its versatility and performance.
How It Compares to Alternatives
Compared to other grease remover sprays like Purple Power or GUNK Foamy, this product offers more natural citrus content with a less harsh odor.
While competitors often require a follow-up rinse to remove chemical residue, Chemical Guys’ formula leaves surfaces cleaner with a fresh scent. It’s more versatile than single-purpose products such as engine-only sprays, since it tackles tire cleaning, tools, and undercarriages with one bottle. Price-wise, it competes well for a professional-grade undercarriage cleaner, though budget shoppers may find larger gallons of all purpose degreaser a bit more economical in bulk.
The warranty and customer support from Chemical Guys is generally rated above average in this segment.
Who Should Buy This Product?
This tool is ideal for auto detailing enthusiasts, DIYers, and mechanics looking for professional results at home. Shop owners who frequently need an engine cleaner spray will appreciate the concentrated, heavy duty cleaner in this bottle.
If you restore classic cars, regularly clean multiple vehicles, or deal with stubborn oil grime removal, this device offers both efficiency and convenience. Those sensitive to citrus scents or seeking ultra-budget solutions may prefer a generic all purpose degreaser instead.
