In-Depth Review
Powerful Cleaning Without the Chemical Hangover
Grease Monkey’s Bison line is a favorite on YouTube detailing channels for its ability to cut through stubborn grease while remaining safe for the user and the environment. This bio-based formula is derived from soy and corn esters, providing a non-toxic alternative to the petroleum-based degreasers typically found in auto shops. For the thru-hiker who maintains their own vehicle or mountain bike at trailheads, this ensures no harmful chemicals leach into the forest floor.
Safe for Sensitive Components
Unlike harsh caustic cleaners, the Bison degreaser is safe on rubber hoses, plastic trim, and carbon fiber bike frames. It is a 'concentrated' formula, meaning a single bottle can be diluted for various tasks—from cleaning a muddy engine bay to degreasing a mountain bike chain after a dusty ride. This versatility is highly valued by athletes who need to maintain multiple pieces of equipment with minimal supplies.
| Application | Dilution Ratio |
|---|---|
| Engine Bay | Full Strength |
| Bike Chain | 1:1 Water |
| Wheels/Tires | 1:4 Water |
As an Indigenous-owned brand, Grease Monkey prioritizes the protection of water sources. Their manufacturing facility uses a closed-loop water system, and they source their bio-feedstock from fair-trade agricultural cooperatives that practice regenerative farming. This ensures that every bottle contributes to a healthier ecosystem.
Pros
- ✓No toxic fumes
- ✓Safe for bike frames and car paint
