Powerful Drain Cleaner & Unblocker l 1KG Caustic Soda | Fast-Acting, Heavy-Duty Sink & Drain Cleaner | Strong & Effective | The Original & Best l Works 3x Better Than Bleach (Packaging Varies)

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.

When members of the family have a tendency to allow all sorts of rubbish to be flushed out of the kitchen sink, you need something good to clear the drain when it gets blocked. I've often used caustic soda so bought this specifically for that purpose. Just pour the crystals over the muck blocking the drain and leave for an hour or so and then wash away.Also good for making soap if that's your thing (make sure you know what you're doing).

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.

Instantly unblock the drains

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.

its good it works. big bottle. mr muscle works easier better and faster though.

Works very well

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