Block Out

Block Out is a drain cleaning chemical, described by the manufacturer as a heavy duty scavenger for blocked sinks, toilets and drainage lines. The listed ingredients are sodium metasilicate, caustic soda (sodium hydroxide) and citric acid. The manufacturer describes it as formulated to break down grease, hair and food waste in pipes. These are the manufacturer's statements of function and have not been checked against test data. Buyers are hardware and plumbing supply distributors, cleaning product wholesalers, facility maintenance companies and retailers. The only pack format listed is a plastic jar with a screw cap. The record does not give the net weight of a jar, so ask for it. Caustic soda is a corrosive substance. Ask for the safety data sheet, the hazard labelling and the transport classification with your quote, and check the chemical import rules of your destination country.
