Bison 300
Bison 300 is, to say the least, industrial strength - it's like a volcano in a drum. Containing more than 50% active ingredients, Bison 300 breaks down the most extreme grease, tar, asphalt residue, etc. Usually used in highly diluted form. Bison 300 is green - biodegradable, with bio-based and nature-sourced active ingredients - but too concentrated to receive Green Seal certification.
