Best Toilet Unclogger Liquid: Complete Guide

Type of Drain Cleaner

There is a variety of liquid drain cleaners, each with a different purpose. We have enzymatic, caustic, and acidic drain cleaners.

Enzymatic drain cleaners, as the name suggests, pack enzyme-producing bacteria that feed on clogs. Generally, enzymatic drain cleaners do not handle tougher clogs, such as grease and soap scum. They are, however, pretty efficient in dissolving soft materials, such as hair and paper. Typically, this gentle formulation is free of toxic substances. Hence, protective gear is not a must-have.

Caustic drain cleaners are pretty much alkali-based chemicals. It converts the clog into a soap-like substance, making it easy to dissolve in water. Well, caustic drain cleaners are less toxic than their acidic counterparts. Also, they are gentle on your pipes. However, avoid using them on old pipes, say 20 years or more. Choose caustic drain cleaners if you want to remove food, soap scum, and grease clogs. And since they tend to cause irritations, I recommend you wear safety gear.

Acidic drain cleaners are pretty much the most powerful. They provide heavy-duty cleaning for all types of clogs, including grease, soap scum, paper, hair, and food. Also, acidic cleaners use a fast-acting formula. In most cases, it dissolves tough clogs in under 15 minutes. However, like caustic cleaners, acidic drain cleaners can damage old pipes. Also, they demand safety gear during use.


Whichever type of drain you want to clean, you are most likely to encounter standing water. Hence, I recommend using a toilet unclogger liquid that can cut through the water and penetrate deeper into the drain.

So, aim for a drain cleaner that has a thick gel-like formula. It will cut through the water and cling to the pipes to keep them working. Well, using a lighter formula will only work above the waterline, making it impossible to get rid of clogs.


Size, specifically the quantity of the drain cleaner, matters a lot. Even the most powerful acidic drain cleaners might require repeated treatments for the best results.

Well, you cannot get repeated treatments from a small bottle of toilet unclogger liquid, not unless you buy multiple bottles. So, I recommend buying in large quantities, at least 30 ounces. Such amount will last 4-6 treatments, eradicating the clog.

Pipe and Septic-Safe

Well, drain cleaners will no doubt get in contact with your piping system. And once the cleaning is done, it all ends up in the septic system.

Hence, it is good to consider a drain cleaner that is gentle on your plumbing and septic systems. Also, it should work with all pipe materials, including plastic and metal. After all, you do not want to incur extra costs for damaged plumbing or septic system.

Clog-Free Guarantee

I have come across many drain cleaners that claim to provide clog-free protection. However, they do not provide anything for reassurance. Hence, if possible, consider cleaners that provide guaranteed results. Should it not work, you have a chance of getting your money back.


Do not only choose a safe drain cleaner. Also, aim for one that is easy to use. After all, you do not want a drain cleaner that will also require plunging work. Instead, aim for a clog remover that you pour, let it sit, and do its magic. Also, if possible, consider pre-measured drain cleaners. It will save you the extra work of mixing to get the right ratio.

Frequently Asked Questions (FAQs)

Question: Can a toilet unclog itself?

Answer: It can, but not always. However, it will take quite a long time to do so. Again, it is only possible for water-soluble materials. And even in the event it does, it is less likely to clean the residues that cling onto the pipes. Hence, such a task should be left to the toilet unclogger liquid.

Question: After the drain cleaner has done its job, should I flush it with hot or cold water?

Answer: Well, you can use cold water. However, you have a chance of dealing better with the clog by using hot water. It speeds up the dissolving process, loosening up the clog much faster. But ensure the water does not reach boiling point as it can deform plastic pipes.

Question: What enzymes break down clogs?

Answer: Well, there are different types of enzymes for the different clog materials. The most notable are cellulose, lipase, protease, and amylase. Cellulose works best on paper. It can, however, break down some food matter. Lipase works best on fats while protease breaks down proteins. Amylase, on the other hand, breaks down starches.


I hope you now know the uncontested champions in the world of liquid drain cleaners. Even more, you are now aware of how much time and effort the best toilet unclogger liquid can save you. Save yourself the trouble and the extra cost of professional plumbing service by picking the best toilet clog remover on the list.
