Unitedlys® Caustic Soda Drainage Block Remover 350G | Fast-Acting, Non-Toxic & Odorless Drain Cleaner Powder | Caustic Soda for Drain Cleaning | Sink & Pipe Drainage Cleaner

The Caustic soda flakes worked very efficiently for clearing blockage, but please be very careful while using them . 🚨The smell is extremely pungent and irritating to the eyes and nose, so wearing gloves and staying in a venti what does ventilated what does ventilated area is highly recommended. For the best results, I use around 3-4 L of boiling hot water in a blocked pipe/drain first. Then I added about 2 lidfulls of the flakes from the container and left it around for 15-30 minutes. After that, I put more hot water and the blockage cleared completely. The water started flowing prefectly again without any issue

Good Nice Product

Great 👍

This product is great but 3 times priced than local plumbing shop

Very Reactive. Good product

Completely Useless & Waste of Money I used the product exactly as instructed. The first time, I used around 6 spoons from the 900 g pack, but there was absolutely no reaction, no foaming, and no unclogging. I then used the remaining product as well, hoping it would eventually work, but there was still no reaction and absolutely no result. The blockage remained exactly the same. Very disappointing. The product claims to be an ultra-fast drain and grease remover, but in my experience it did nothing at all. Complete waste of money. I would not recommend this product.

The very strong alkali flakes dissolve in water and you get a ready cleaning agent . It cleans fast. Please take care of your hand the strong alkali may burn your hands if you are not wearing a good hand glouse.

Excellent product
