Caustic Drain Cleaner for Stubborn Blockages

Northfork Drain Cleaner, code 632040700, is sold here as a carton of 3 x 5 litre bottles for maintenance staff, cleaners and facilities managers who deal with slow or blocked drains.

Northfork says it is formulated to clear stubborn drain blockages and remove the unpleasant odours that come with them, and that it suits all drain types but not septic tanks. ACCO's safety data sheet lists sodium hydroxide solution at 10 to 30% and classifies the product as dangerous goods, UN 1824, Class 8, Packing Group II, with the signal word Danger.

Dosing is measured rather than guessed: Northfork gives 500ml for a partly blocked drain and 1 litre for a fully blocked one, left to stand for at least 30 minutes and flushed with cold water. If the drain has not cleared, Northfork advises calling a licensed plumber.

Store it locked up, as the safety data sheet directs, and keep that sheet close by for anyone who uses it. Compare other chemical drain cleaners, see bathroom and toilet cleaners, browse cleaning chemicals, or explore the full Northfork range for regular washroom care.
