Restaurants, hotels, homes and other food preparation facilities often experience sanitation problems associated with the organic material that accumulates in drain lines, cracks and crevices, and other non-drain sites. * These problems include drain and filth-breeding fly infestations, noxious odors and slow drains. * The most effective method of correcting these problems is to remove the organic material. * Treating these problems with ordinary drain cleaners, hot water, detergents, bleach, or ammonia is ineffective. * The most effective solution is the use of a highly concentrated biological product with specially selected bacteria strains. * DrainGel is a highly-concentrated gel which clings to the sides of drains and pipes. * DrainGel can also be easily sprayed into cracks and crevices and onto hard-to-access non-drain sites. * DrainGels formulation incorporates specialized microorganisms in combination with biological support ingredients and essential growth factors. * This unique formulation promotes improved performance in degradation of organic materials in both aerobic and anaerobic environments. * DrainGel is also specifically designed to block the production of odors frequently occurring in drain lines, sewer lines and grease traps.
