Zep Heavy-Duty Floor Stripper Ammonia Free Concentrate - Deep Cleaning

In this review of the Zep Heavy-Duty Floor Stripper Ammonia Free Concentrate the bottom line is clear: this is a practical choice for facilities and homeowners who need to remove old polish and heavy buildup from hard floors quickly and without ammonia fumes. The reviewer found the concentrated formula effective at dissolving multiple layers of finish, and appreciated that one gallon makes nine gallons of working solution, which stretches supply for larger areas. For anyone preparing floors for a fresh finish, this product delivers powerful, low-foam stripping action that works well with a scrubbing machine or a mop and wringer.

Key Features

• Heavy-duty stripping: Removes stubborn finishes and heavy buildup so floors are ready for recoating or refinishing.
• Ammonia-free formula: Reduces strong ammonia odor while still offering strong alkaline performance for effective stripping.
• Concentrated mix: One gallon of concentrate yields nine gallons of solution, lowering storage and dilution frequency for large jobs.
• Low-foam application: Works well with a scrubbing machine or a cotton mop and wringer, minimizing rinsing and machine clogging.
• Versatile floor use: Suitable for vinyl composition tile, rubber, terrazzo, and concrete, making it useful across commercial and residential settings.

Who It's For

The Zep Heavy-Duty Floor Stripper is aimed at janitorial teams, facility maintenance crews, and homeowners tackling large areas that have accumulated multiple polish layers or heavy buildup. Its concentrated, high-alkaline action is particularly useful where mechanical scrubbing is available, because it speeds up removal and reduces labor time.

Those who should look elsewhere include people working with marble, natural stone, or wood floors, since the product is not recommended for those surfaces. If a neutral-pH daily cleaner or a nonstripping maintenance product is needed, choose a specialty cleaner designed for delicate or finished floors.
