Tough Duty NB is a non-butyl, ready-to-use cleaner/degreaser. Specially formulated without butyl, Tough Duty NB is recommended for use in facilities where butyl cleaners are restricted or, for users who prefer a butyl-free formula. Safe for use on nearly every washable surface, use Tough Duty NB on walls, partitions, floors, vinyl, chrome, stainless steel, formica, fiberglass, synthetic rubber, white wall tires, porcelain, and ceramic. This unique ingredient combination provides unusual ability to quickly penetrate and remove both food and industrial type grease-based soils. The wetting action of Tough Duty NB is immediate even on heavy build-ups.
