Blocked kitchen sink and ... one-shot?


Recommended Posts

Has anyone used/would/wouldn't, used one-shot (acid) to clear a semi-blocked kitchen sink ( likely the long pipe under out kitchen floor? )

Any guidance would be most welcome!

It may not be environmentally friendly but I've found caustic soda works, pour it down while it's hot. You'll need windows wide open, the fumes are strong, and if you spill it on yourself you'll know it!

Caustic soda definitely works but can work too well, actually dissolving the pipe or the joints! Spilling it on skin can lead to permanent tissue damage and in the eyes, blindness.

One-Shot works well but carries the same caveats as caustic soda. It can also be difficult to source since the acid attacks of recent years.

If you do use these highly caustic or acidic cleaners wear thick rubber gloves and eye protection. Also a good idea to spread petroleum jelly around the plughole to help protect it from corrosion.

As you pipe is only semi blocked I'd try one of the modern enzymatic cleaners. It uses bacteria to eat it's way through the sludge. Best added last thing at night and left to work overnight. Won't damage the fitting, or you and is environmentally OK.

Thank you all.

I'll try an enzymatic ( surely a great name for a 1960's car ? ) one first and 'see' what happens.

Try using standard household ingredients ... baking soda followed by apple cider vinegar.

They combine and create a chemical reaction ... see YouTube or Google for guidance. 😉

Update: the only thing - and I mean only - that worked after many other attempts, was oneshot... 

[ Using long rubber gloves, eye protection etc. ]

Just bought some One Shot myself yesterday for the same thing.
