When people have a clogged drain, they typically go for a chemical drain cleaner to fix it. However, there's a lot of conflicting information regarding the safety of these products, and many worry that using them will harm their plumbing. So, here's what we think. Drain cleaners can effectively clear clogged drains, but they are not always safe. Most over-the-counter drain cleaners contain harsh chemicals, such as sodium hydroxide or sulfuric acid, that can harm the environment, pipes, and even people. These chemicals can cause severe burns if they come into contact with the skin, eyes, or mouth, and they can also damage pipes, especially if used repeatedly. Additionally, if you accidentally combine two different drain cleaners (maybe one didn't work and you tried another), it can release toxic fumes that will burn your lungs, eyes, and throat. Imagine a house filled with chlorine gas, and you get the idea. Finally, if the product doesn't work, it can leave the acid sitting in your pipes, which could lead to corrosion and bursts. While chemical drain cleaners may seem like an easy solution, it is generally safer to avoid them and call a professional plumber to clear your drains using safer and more effective methods.
