Different Types of Drain Cleaners
Another factor to keep in mind when considering a drain cleaner is which type to select. The 3 most common types you can find nowadays are caustic, oxidizing, and acidic cleaners.
1. Caustic Cleaners
Caustic drain cleaner contain lye substances and caustic potash. The hydroxide ions of these two bases create the chemical reaction that effectively clears the clogs. Their alkaline or basic chemicals emit heat, turning the grease into a liquid substance.
2. Oxidizing Cleaners
Oxidizing cleaners contain substances such as household bleach, nitrates, and peroxides. They cause the organic material clogging the drain to oxidize and lose electrons. As they are heavier than water, they easily move through the water, releasing gas and heat.
3. Acidic Cleaners
The most common type of cleaners is acidic cleaners. This type can be found at almost any store, and is the most commonly bought option by plumbers. Acidic cleaners are so popular thanks to the high concentrations of hydrochloric and sulfuric acid, which work well to clear drains.

Buyer Guide for Unclogging Drain Cleaners
In case you’re having trouble deciding between the different options we’ve recommended, or you want to look for some additional choices, here is a brief buying guide to help you pick the perfect cleaner for you.
Overall, there are 4 main criteria to keep in mind:
1. Drain Cleaners – How They Work
Before we get too deep into the details, it is important that you understand how they typically work. Overall, they contain either liquid or powder chemicals that actually dissolve the obstructing material causing your clogged drain. Depending on the chemicals used, drain cleaners can work more quickly, fix more powerful clogs, but also be more unsafe, so it’s important to consider a balance of strong but safe chemicals for your cleaner.
2. Type of Clogs
Different ons work on different types of clogs. Some may be more effective than others, depending on what is causing the clog in the first place. Therefore, you must always make sure that the cleaner you are planning to buy is appropriate for what’s causing the clog.
Most of the time, drain cleaners for clogged toilets are designed to dissolve hair, grease, paper, soap scum, kitchen waste, or other organic materials. However, if some object is causing the clog, a toy, for instance, these are not the right solution. Therefore, double-check your cleaner will work to dissolve the substance blocking your drain and you should have no trouble.
3. Time Of Exposure
Another important factor to keep in mind when buying a drain cleaner is the time of exposure. Some cleaners can take up to a couple of hours to break down the clog, while others can do the same thing within minutes. Especially if you’re planning on using a safer, lower-chemical option, be prepared to need to wait longer for the product to work.
4. System Compatibility
Finally, it’s crucial that the one you buy lines up with the type of drain you’re hoping to clear. Sometimes, they have a high amount of chemicals that can ruin the drainage system. Therefore, make sure the cleaner you pick clearly states that it can be used for the pipe material you need. Some cleaners work with just metal, others can be used on PVC pipes, and some can be used on multiple materials. Just be careful to pick a cleaner that’s compatible with your system to avoid any additional damage or issues.
Safety Concerns
As we’ve mentioned, some drain cleaners contain harsh and dangerous chemicals and thus, it is important that you know how to use them properly. Please keep these safety concerns in mind when selecting and using a chemical product:
- Follow the instructions – No matter what, you must always stick to the instructions provided with the product. For example, one detail most manufacturers mention is keeping the room well-ventilated while using their product. If the room isn’t well-ventilated, you could end up inhaling chemicals directly, which can be harmful for your health. Additionally, never leave the cleaner inside your drains for longer than stated.
- Wear protection & pour carefully – Always wear eye protection and gloves when pouring. If the drain cleaner you use contains dangerous chemicals and happens to splash out while pouring, it could burn your skin or eyes. Therefore, pour slowly and carefully to avoid spilling, and wear protective gear to be extra safe.
- Don’t combine products – Never mix them with other cleaning products, not even with homemade cleaners. Because of the different chemicals used in drain cleaners, mixing substances could cause a chemical reaction, which can create toxic gas or even cause an explosion. Always follow the package instructions and only use one cleaner at a time to avoid any unexpected issues.
- Always flush the drain – Last but certainly not least, don’t forget to flush the drain after using them. After allowing the cleaner to sit for the recommended time, flushing will clear away the dissolved materials as well as any remaining cleaner to leave you with a working toilet once more!
Our Bottom Line
Drain cleaners for clogged toilets are definitely something you want to have in your home. Although they may not be able to destroy clogs caused by solid objects, they do an amazing job of dissolving grease, hair, soap, and other common organic materials. If you are looking for a great quality-to-price ratio, the Green Gobbler Liquid Hair & Grease remover makes a great choice. It is much safer than other traditional cleaners and it is completely odorless.
On the other hand, if you need a drain cleaner that can break down clogs more quickly, the Rid-X Septic Tank Treatment Enzymes cleaner is a perfect choice. It keeps a healthy balance of bacteria in your pipes and even helps prevent clogs from recurring.
