Pros and Cons of Chemical Drain Cleaners

Do you have a clogged drain in your home? Then you must be wondering whether to use chemical drain cleaners or call drain cleaning professionals. The choice can be confusing for many, yet most resort to using drain cleaners as they are cheaper. But is it the right choice for you? To figure that, you need to consider the pros and cons of using chemical drain cleaners, like.


1) Easy to Use

Chemical drain cleaners are fairly simple to use; all you have to do is pour it down your drains and wait for them to work their magic. You don’t even need any special equipment or training for that.

2) Effective on Hair, Grease, and Food Clogs

Chemical drains are compounds that come in contact with the clogs and start reacting to them, and this process either dissolves the clog or loosens it up so it can be cleared. Hence, chemical drain cleaners are sometimes perfect for removing small clogs developed due to hair or grease.

3) Unlikely to Cause Damage

Chemical drain cleaners generally do not cause any kind of damage to your drain pipes since they are not strong enough to react with such materials in the first place.

4) Eliminates Bad Odour

Since they work by diffusing clogs, they can also wash down the grease from your drain lines. This can significantly remove the rancid smell that the drains often emit.

5) Inexpensive Solution

Chemical drain cleaners are cheap, and you don’t need any license to purchase them (except for acid-based drain cleaners that are only sold to licensed drain cleaning professionals). Hence, this makes them an excellent bang for your buck if you face any small clogs.


1) May Contain Pollutants

Some drain cleaners contain toxic pollutants that are not good for the environment, and if they leak out of the drainpipe, they can contaminate the soil as well as groundwater. And usually, many manufacturers don’t mention this on the packaging, so it can be hard to figure out.

2) Not Safe for Garbage Disposals

Most chemical drain cleaners are not safe for garbage disposals and can cause a splash-back, throwing the liquid into your eyes or mouth. This can cause significant health issues, including chemical burns.

3) Not Suitable for Septic Tanks

If your drain line is connected to a septic tank or a cess-pit, then using chemical drain cleaners can cause damage to your septic tank and cess-pit.

4) Not Safe for Total Blockage

If you have a complete blockage in your drains, then chemical drain cleaners may fail to dissolve the clogged up materials and wash them down. In such a case, it may also get stuck in the drain, which can, over time, damage your pipes.
