What can I use to unblock my drain UK

You can unblock your drain with baking soda, salt and hot water. You can also use a plunger and sulphuric acid. If these methods are not effective, you can try baking soda and vinegar. These solutions can remove most of the clogging substances from the drain.

Caustic soda

Caustic soda is a chemical that can be used to unblock drains. It’s a corrosive substance that dissolves in water and can be purchased at any hardware store. While it will unblock some drains, you should be aware that using a large amount of this chemical can lead to serious problems. Caustic soda should always be handled with extreme caution, and it should be kept out of reach of children. Caustic soda is a great way to clear a blocked drain, but it must be flushed through properly to avoid the risk of the residual material hardening into cement.

Caustic soda is available in two forms: a powder and a liquid. Both forms contain sodium hydroxide, which can cause chemical burns. For this reason, it’s important to wear rubber gloves and protective eyewear. Caustic soda can be mixed with cold water and will create a fizzing sound and heat when added to it. Once the mixture reaches the drain, it should be able to unblock it in about three to four minutes.


Plungers can be an invaluable tool when it comes to unblocking drains. They are an easy and cheap way to clear blockages from your sink, toilet, or bath. They work by releasing compressed air into the blocked area, forcing it down the pipe until it breaks up into small pieces. They can be used to unblock any size drain.

Generally, a plunger consists of a cup attached to a stick and is sized to fit into the clogged area. This cup pulls on the clogged material and creates a suction in the process. Then, the material can be flushed out with hot water. If it’s not possible to use a plunger, there are many DIY options to clear a blocked drain, including boiling hot water, baking soda, and vinegar.

Sulphuric acid

Sulphuric acid is a powerful chemical that can be used to unblock your drain. It can dissolve organic material and is safe for use in drains. However, it is important to use proper safety equipment before using it. Make sure you wear a pair of safety goggles and long rubber gloves. Also, make sure you have plenty of ventilation in the room where you’re working. You may also want to turn on an extractor fan and face it towards an open window.

Sulphuric acid is easy to use and can help unclog your drain within an hour. It is a natural acid that dissolves the clogging materials and is safe for septic and sewer systems. The most effective solution has a concentration of 98% sulfuric acid. Higher concentrations will break down into a less corrosive product. However, you should always wear lab coat and safety goggles when handling sulfuric acid.

Baking soda

One of the simplest ways to unclog your drain is by mixing baking soda with vinegar. Just pour the mixture down the drain, and wait for a few minutes before flushing. The soda crystals will help break up any soap residue and remove the blockage. If this doesn’t work, try cleaning the u-bend by pouring hot water down the drain.

If you don’t want to use a chemical drain cleaner, you can use salt to unclog your drain. It’s an excellent cleaning ingredient that has both antiseptic and abrasive properties. Plus, salt is inexpensive and most people have some in their cupboards. You can make a solution by mixing half a cup of salt with one cup of water and pouring it down the drain.


There are a few different chemicals you can use to unblock your drain. These chemicals have degreasing properties and can easily break up any blockage in the drain. However, you should be aware that these chemicals have very strong exothermic properties and are potentially hazardous to your skin and eyes. Other chemical options include sulphuric acid and caustic soda. These chemicals can break down a wide variety of materials, including grease and fats, and generate heat that can melt a blockage.

Caustic soda is a common chemical used to unblock drains. It dissolves in water and is available in a liquid and powder form. You can purchase this chemical at most hardware stores.
