Powerful Drain Cleaner & Unblocker l 1KG Caustic Soda | Fast-Acting, Heavy-Duty Sink & Drain Cleaner | Strong & Effective | The Original & Best l (Packaging Varies) (1KG, 1, count)

Used this stuff years ago in my first flat and couldn’t find it again for ages!So happy I made my purchase, this is absolutely great stuff to use for unblocking drains, also the label does say only use with cold water and use exact measurements but you don’t need to.I pour in some powder and then boiling kettle water and it works instantly, the reaction is a lot faster and it foams up & spits (just don’t use too much, test your water drainage in between pours.Do make sure you wear a mask/goggles and gloves as per instructions, especially using the hot water as the reaction is a lot stronger.It works within a second this way.I’ve used a lot of drain unblocking products but NOTHING has ever worked as well as this.

This product is so good at cleaning smelly sinks and drains. I am currently cleaning out a grimy aquaroll. I will be cleaning out caravan waste pipes with it soon. Very prompt delivery. Well packaged. This product does what it says and more. Try to remember to wear disposable gloves, I always forget. It is really strong stuff. Read the label for safe use. Really good value, open safety cap and pour, easy. Keep out of reach of children.

I'm unsure of the various quality levels of caustic soda, if indeed there are any, but this product performed the task of cleaning / clearing drains very well.

warning: it is highly toxic so keep away from kids/pets and it will eat aluminium fittings and pipes so check first.when your bath drain stops flowing properly, sprinkle some down the hole dry, leave for 5 mins then flow a small amount of water and let it sit. you may hear it hiss and it will get warm as it eats the hair/skin proteins and dissolves the soap. pour some more down and repeat. leave 30 mins and then flush through with plenty of water and viola your drain is clear. leave the water running for 10 mins to flush it all away and job done. each use is about 100g total so 1kg lasts for years.imo don't waste your time with supermarket or branded "eco" drain cleaners they are expensive, terrible and rarely work properly for the stubborn hair/soap blockages (they actually cause environmental damage as you have to use more, every few weeks) especially if a cowboy plumber didn't plumb the drain correctly so lets waste water sit in the pipe...plastic pipes have no issues but if you have metal fittings make sure you wash it all away thoroughly to avoid any potential issues with flux/fittings/rubber etc NaOH is highly corrosive to metals and organics so don't leave it on your skin too long, it'll feel slimy until you fully wash it off. again, keep away from kids, pets, food and eyes ie basic chemical safety and you'll be fine.

Not the best at the job its meant for.

Clears drains fast, use with caution and it does what its meant to. Good price when I purchased and quality is as its meant to be. Clears blockages fast for most household situations good effective product.

I am pleased to inform you that I received the product that I bought recently from the amazon arrived on time and I like the price and the quality. So I use it to unblock my toilet and sink,thanks for that.

Cleared blockage in sink no problem, does exactly what it says on the bottle…
