GlobalTech® Heavy Duty Degreaser (HDD) is an aqueous cleaner that is more than 90% water based with all ingredients being 100% active. It has been specially formulated to remove all types of grease, oil, grime, and dirt from all types of surfaces including machinery, engines, farm equipment, trucks, buses, trains, tools, work benches, floors, walls, kitchens. Our HDD utilizes a proprietary "electro-chemistry" technology to clean that works by reversing the normal polarity of the contaminant. The reversal of the polarity causes the like charges of the contaminant and the work surface to repel each other, thereby preventing re-attachment to the surface, enabling them to be rinsed or wiped away with ease. HDD has a unique ability to penetrate crevices and orifices to dislodge microscopic contaminants. This method of cleaning drastically improves the cleaning efficiency by minimizing the amount of rinse water needed. Because HDD leaves no ionic contamination behind, it is an excellent cleaner to be used when cleaning electric or electronic equipment and hardware.
