Double Duty is an aggressive, synthetic degreasing detergent without odor or toxicity, the company says. When diluted 1:5, the detergent can remove more grease and oil than most other detergents, the company says. The product is biodegradable; has a neutral pH; does not contain phosphates, silicates, or solvent; and can be used in low- or high-pressure equipment, or as a spray and wipe, according to the manufacturer.
