Mr McKenic®- Choke Clear is formulated to clear blockage problems that cause slow and inefficient drainage in most water drain pipes. Clogged drain pipes are common problems faced in areas like air-con units, kitchen sinks, toilets & any place where drainage of wastewater is required. Often, such problems are caused by obstruction of solid materials or buildup of dirt and scum. Overtime, algae, scale & slime will grow and form the layer of clog along the inner pipes. If this persists, it will encourage the growth of unwanted bacteria and bad odour. The product effectively breaks up any buildup of rust, algae, scale & slime found inside drainage pipes. Its hassle-free application requires minimum dismantling & gives users the convenience of pouring the product into target areas without the need to scrub! As a preventive measure, Mr McKenic®- Choke Clear may also be used to maintain drains and toilets to prevent chokes.
