Other Ways To Clean Your Drains

There are a few other ways to clean your drains, if you don’t want to use either of these chemical cleaners. You can try any of the following:

  • Use mechanical methods that go down the drain to clean them, such as plumber’s snake
  • Use homemade remedies

Liquid Plumr Vs Drano

Both of these products are chemical cleaners. They contain sodium hydroxide and sodium hypochlorite.

Drano is a drain cleaner that was invented in 1923. It was created by S.C Johnson & Son, an American manufacturer. This company held 90% of the market for drain cleaners, until Liquid Plumr came on the scene.

Liquid Plumr relied on heavy advertising, and managed to take over half of the market.

Liquid Plumr

Liquid Plumr has a triple action formula that is great for cleaning the drains. It provides fantastic benefits.

This product is great at being able to pour through water that is standing in the drains. It can also unblock full clogs, protect pipes and fight those horrible odors that you so want to get rid of! It also helps to protect the pipes if you use this great product often.


Liquid Plumr contains two active ingredients. These are sodium hydroxide and sodium hypochlorite, also known as bleach.

How Does Liquid Plumr Work?

When you mix this product with water, it will react. The bleach will react with the sodium hydroxide, making the product corrosive. It also releases heat.

Once it has become corrosive in this way, it will then travel through the pipes. The product will break down any blockages that it comes into contact with.

It will take around 15 minutes for this product to unclog the drain that it has been placed in. It works very quickly and effectively.

If you haven’t used the product in a long time, then you can always carry out the process twice to make sure that there are no blockages in the pipes.

Pros Of Liquid Plumr

Liquid Plumr is a fantastic product to use in order to keep your drains nice and clean. It is great for many reasons. These are:

  • Works Quickly

This product works very quickly. It is very fast and can unclog drains in less than 15 minutes!

  • Won’t Damage Your Plumbing

This product, while it is corrosive, will not damage your plumbing. It is designed to degrade the blockages, but not the pipes. They do not harm the bacteria in the septic systems.

  • Multiple Options

There are many different variations of this product. You can choose which one suits you best, depending on what you need it for, or personal preference.

For instance, there is a Liquid Plumr Foaming Pipe Snake which will thicken into a foam and get into all the small places.

Cons Of Liquid Plumr

Liquid Plumr does have some negative aspects to it, too. These include:

  • Damage Rubber Pipes

This product is too strong for rubber pipes. You should not use this product on rubber pipes at all as this can damage them and cause big issues in the longer term.

  • Can’t Be Mixed With Ammonia

This product shouldn’t be mixed with ammonia. This is true of any product that has bleach in it, as these products will react with each other, creating a poisonous gas.

  • Not As Successful With Toilet Blockages

Liquid Plumr is not as good at dissolving the matter that clogs toilets. It is much better when it is used in other drains.

Drano is an affordable and reliable way to unclog your drains. It will not cause any plumbing problems, or problems with your septic tank.

One of the main ingredients in Drano is sodium hydroxide, which is also in Liquid Plumr. As well as this, Drano has aluminum shards in it which creates a chemical reaction.

The chemical reaction that is produced generates a heat that is nearly the temperature of boiling water. This heat helps to break down the decomposition process.

The ingredients in this product also react with grease. It turns the grease into a soap which is dissolved with water.

After this chemical reaction has taken place, it prompts another. The product then reacts with the aluminum. This reaction causes hydrogen bubbles to form which can loosen particles in the drains.

This product starts off several different chemical reactions in a row, which make it a very strong and powerful product.

Pros Of Drano

Drano is a fantastic product which has been around for 100 years. It has stuck around for lots of different reasons. These include:

  • Ease Of Use

Drano is very easy to use. The instructions are simple and clear, and you won’t need any specific skills to be able to carry out this process. Simply read the instructions, and do what they say!

  • Dissolves Stubborn Clogs

Cons Of Drano

There are some downsides of using Drano over other products.

  • Strong Chemical Reactions

This product creates very strong chemical reactions. While they are designed to break down clogs, they can sometimes cause damage to PVC pipes. Some plumbers recommend using lighter chemical cleaners.

  • Can Be Harmful

If this product is not used correctly, then it can be harmful. Sometimes, the product may splash up, causing burns to your skin.

As well as this, the product may sometimes have a chemical reaction with other cleaning products that you may use, and this can cause toxic fumes.

It can also be harmful to the environment as it can cause dangerous toxins to be released in the water.

  • Can’t Unclog Toilets

This product is heavier than water which means that it will not travel up the toilet to reach the area where the clog is. Instead, it will just sit in the toilet bowl.
