Do you want to unblock a clogged drain or clean a stained floor? Caustic soda can do the trick. Caustic soda, or sodium hydroxide, sells in the form of a white granular powder that is soluble in water. The resulting solution makes for an effective cleaning agent that can unblock drains as well. If you wish to use caustic soda to unblock a drain, you have to make a solution using 500 g of caustic soda and 5 litres of water. To clean floors, mix around 125 g caustic soda with 5 litres of water.
When using caustic soda, make sure that you do not come into direct contact with the solution. This can lead to tissue decomposition, heat burns, and even blindness. Sodium hydroxide is easy to purchase on eBay, and it sells in different quantities, such as 100 g, 500 g, 1 kg, and 5 kg. Look forward to a sparkling new floor or an unblocked drain, but use this chemical with care.
