Zep Industrial Purple Cleaner and Degreaser Concentrate - Powerful

In this review the Zep Industrial Purple Cleaner and Degreaser Concentrate is presented as a heavy-duty cleaning option for shops, garages, and construction sites; the bottom line is that it is best for users who need a concentrated, economical degreaser capable of penetrating baked-on grease. The reviewer found the single biggest reason to buy is its concentrated formula that yields up to 25 gallons of ready-to-use solution from one gallon of concentrate, which delivers strong cleaning power across unfinished concrete, metal, and other tough surfaces without excessive foaming.

Key Features

• Powerful Formula: The concentrate penetrates and removes industrial grease and grime so heavy machinery and engine parts come clean with less scrubbing.
• Versatile Use: It works on a wide range of applications including shop floors, construction equipment, and engine bays for consolidated cleaning supplies.
• Surface Compatibility: The cleaner is effective on unfinished concrete, metal, fiberglass, masonry, and asphalt so one product covers many jobsite surfaces.
• Low-Foam Performance: Low foaming means rinsing is quicker and you avoid residue buildup on large horizontal surfaces.
• Economical Concentrate: One gallon produces up to 25 gallons of ready-to-use cleaner, reducing cost per use for frequent or large-area cleaning.

Who It's For

This product suits professional shops, maintenance crews, and serious DIYers who routinely tackle heavy grease, oil stains, and ground-in grime on equipment and floors. Buyers who value dilution control and economical purchasing for repeated large-area cleaning will appreciate the concentrate format and low-foam rinse.

Those who need a mild, cosmetic cleaner for delicate painted surfaces or frequent hand contact should look elsewhere or use personal protective equipment, since customers report it can feel strong and may be harsh on skin if used without gloves.

Pros & Cons
