The Best and Strongest Caustic Soda I've Ever Used! 😍🥰🤩I can't express how happy I am to have finally found pure caustic soda that actually delivers incredible results! This product is extremely powerful, so you need to be careful while using it, but trust me—it’s absolutely worth it.It works like magic in dissolving food residue in the sink, leaving the drain completely clear. I also use it weekly to clean my bathtub, and it effortlessly removes all the hair buildup that used to slow down the water flow.This is, without a doubt, the best and strongest caustic soda I’ve ever used. The results are simply amazing, and I couldn’t be more satisfied! If you’re looking for a high-quality, super-effective solution for drain and pipe cleaning, this is the one.I highly, highly recommend it! 🔥💪🥰🥰🥰🥰🥰🥰

Excellent for soap making

Very nice

Unknown sink blockage, did not make any impact on blockage. Did clean the sink, plug hole and pipe.

Great value, fast delivery and very effective, I used it both for soap making & cleaning a tarnished skink. Fantastic for cleaning, versatile and easy to use ( with goggles). Will buy again.

A good product, but sent via Evri who are falsely claiming to have tried to deliver three times. The driver (Neil) should be sacked.

It seems that full strength caustic soda is getting difficult to find whether in shops or on-line so I was pleased to be able to buy this 99% Sodium Hydroxide. I have used caustic soda for some years now and it is powerful stuff so read the instructions carefully and take great care when using it.

Perfect job, highly recommend 5*****
