Product specification

The most powerful alkaline drain cleaner you will find on the market, Clear-A-Drain is a formidable chemical blend containing a sophisticated mixture of alkaline materials and wetting agents to attack varied types of blockages whether caused by hair, grease, fat, oils, etc.

The heavy-duty drain cleaning formulation is suitable for both the shock treatment of problem drains or for regular dosing as a preventative maintenance procedure.
Clear-A-Drain is 100% water soluble and can be used in hard and soft water areas without issue.

This unique formulation is heavier than water and is designed to bind the active chemical ingredients together, allowing them to sink through other liquids to the source of the problem with minimum loss of activity, even deep within drainage systems! The formula will even remain stable at high temperatures.

Clear-A-Drain is extremely versatile and can be used in all types of drains and grease traps to reduce foul odours by eradicating bacteria, fungi and algae. The product will completely destroy decomposing and rotting matter, which is often the cause of offensive smells, with no harsh fumes.

When dosed regularly, Clear-A-Drain ensures free flowing systems all year round.

Directions for use:

Remove as much water as possible from the sink, drain or toilet to be treated. Pour SLOWLY and directly into the drain over a 10-15 minute period to avoid excessive heat build-up which may damage fittings or pipe work. For sinks and small drains: use 100/200ml. Allow to stand for 10 minutes then flush. For toilet and floor drains: use 250/500ml per application. Allow to stand for 10 minutes then flush. If the blockage persists, seek professional help in disassembling pipe work making sure that all persons are aware of caustic chemicals are presence and the implications for health and safety. Preventative use: apply a small quantity at regular intervals in drains susceptible to blockage.

Handling Precautions:

READ DIRECTIONS THOROUGHLY BEFORE USE, DO NOT mix with acids, chemicals or other cleaning products as a violent reaction may occur. Never stand over the drain while applying CLEAR-A-DRAIN. Do not breathe any vapours which may be created. Allow adequate ventilation. Do not use on aluminium, aluminium alloys or zinc galvanised steel. Keep the container’s cap closed and secure at all times when not in use. Avoid splashes on to decorative surfaces as discolouration may occur. A plastic funnel may be useful for dispensing but the other end should be clear of the blockage to prevent blowback. Under NO circumstances should acid of any type be used to neutralise unwanted CLEAR-A-DRAIN. Wear suitable chemical resistant protective equipment, gloves, goggles, plastic overalls etc. If unsure contact the manufacturer.
