A true breakthrough in drain opening technology. This fast acting Ultimate Main Drain Opener product offers superior performance over traditional drain openers, and is biodegradable and non-irritating to skin. Its high density, thickened formula is heavier then water, so it sinks and clings to the blockage and begins working quickly. Highly effective against obstructions caused by fats, oils, lint, and hair. Green Gobbler Main Drain Opener is odourless, non-flammable, and safer to use then traditional drain openers.
