BENEFITS: Zep Concentrated Tuff Green is a concentrated environmentally-friendly all-purpose cleaner containing a blend of biodegradable surfactants, emulsifiers, and builders. This product is not only versatile, but it provides effective cleaning power. Its detergent system quickly cuts through grease and heavy soil to allow them to be wiped away easily. Since it is a concentrated product, it may be diluted to suit the difficulty of the cleaning job at hand. A dilution of 1:9 will still produce effective cleaning. Zep Concentrated Tuff Green is environmentally-friendly in that all of its ingredients are biodegradable - they will be broken down into minerals, water, and carbon dioxide. The surfactants used in this product are also environmentally-friendly (no APEs). No rinsing is required - just spray and wipe off the surface (except for food contact surfaces).
