How To Choose The Most Powerful Drain Cleaner?
Which Type Of Drain Cleaner Is More Powerful?
There are 2 common types:
(Natural) enzymatic cleaners are formulated with natural bacteria, so it’s slow to remove clogs. However, this type is safe for the environment and less harmful to your health and your plumbing. The enzyme bacteria in the cleaner break down organic soils (food and hair) slowly, so it is less strong than another that can dissolve a complete clog.
(Caustic or acidic) chemical-based drain cleaners work faster and more highly effective, but it’s formulated with harsher ingredients such as hydrochloric acid and sodium hydroxide. These chemicals cause more damage. And the seriousness depends on each type of pipe. For example, a regular use or applying a large amount on PVC pipes can make them warped and softened. Meanwhile, excessive use on metal pipes can corrode your pipes or develop holes on them.
To choose a suitable type of drain cleaner, you need to determine which type of clog you are handling, how fast you want to remove the clog, how old your pipes are, and what your pipes are made from.
How Long Do You Want To See The Result?
Enzymatic cleaners use natural ingredients, so it takes longer to work. Meanwhile, chemical cleaners use harsh ingredients so it acts faster. Some can just work in one or a few minutes while others require your hours, even days.
Which Brands Make The Most Powerful Drain Cleaner?
Green Gobbler
Green Gobbler is famous for enzymatic drain cleaners which are formulated from eco-friendly, non-corrosive, and biodegradable ingredients, so they are safe on any type of pipes from plastic to copper. Because of the lack of harsh chemicals, there is no need to worry about eye, skin, and respiratory irritation.
Drano
Drano is one of the leading brands in producing drain cleaners. Their products are formulated from alkaline chemicals like sodium hydroxide. They are ideal for tough clogs such as grease, food, and soap scum clogs because they can cut right through a thick buildup. Drano cleaners are super powerful, but they are safer than acidic cleaners. However, to protect yourself from harsh chemicals, it’s best to wear protective gear while using Drano cleaners.
FAQs
What are the signs of a clogged drain?
Is there anything stronger than Drano?
Now, Drano drain cleaners are considered as one of the strongest solutions to remove any clogs, but this doesn’t mean that it should be the only choice. Because of its high level of hard chemicals, this cleaner requires you to use it properly and not often. If not, it is harmful to your plumbing and your health, even this product can cause more serious cases.
Instead, if your drain isn’t a stubborn blockage, you can use a safer product with the high effect.
What chemical do plumbers use to unclog drains?
2 common chemicals - Hydrochloric Acid 101 and sulfuric acid are used to unclog drains by plumbers.
The hydrochloric acid 101 is a kind of digestive acid found in the stomach. Its concentrated form is powerful enough to dissolve blocked factors. Only people with a valid plumbing license can buy this chemical because homeowners don’t know how to use this concentrated muriatic acid properly. Without using it in a right way, you can damage your pipe network.
Sulfuric acid is more simple to use, but even a low concentration of this acid is effective enough to break down blocked objects. This solution doesn’t require special training to use it. The acid is widely sold because it is the key ingredient of most commercial unclogged products. However, the sulfuric acid will emit fumes, cause corrosion, even health problems such as skin issues, eye, nose irritation, and death.
Because of some dangerous aspects of these chemicals, they require professional and experienced plumbers to use.
What dissolves hair in a drain?
The combination of soda and vinegar can dissolve hair in a drain, but it takes at least an hour.
The mix of baking soda and salt also solves this problem.
If homemade solutions aren’t effective, buy a commercial cleaning product that is efficient to kill grime, dirt, enzymes, and hair stuck in the drain.
The simplest solution is bleach, but remember to wear protective gear to avoid contacting the bleach directly.
Or you can try with a hair removal cream.
Can drain cleaners damage pipes?
Yes. Drain cleaners damage your pipes if you choose a too strong product for a weak-material pipe. Even when you buy the right drain cleaner for your pipe, avoid reapplying too many times. If not, it eats away at your pipes.
Conclusion
