What Is the Drano Can Made Of?

Drano is made of a few different ingredients, including:

Sodium hydroxide: Also known as lye, this ingredient is a corrosive alkali. It’s commonly used in detergents and is also used in mildew stain removers. It helps to break down things like hair and grease that can clog your drains.

Polydimethylsiloxane: This is a defoaming agent that helps prevent excess foam from being produced during the cleaning process.

Sodium hypochlorite: This ingredient is a bleaching agent that helps to break down organic matter as well as disinfect the surface area.

Sodium Silicate: This is a corrosion inhibitor that helps to protect your pipes and other metal surfaces from the corrosive effects of the other ingredients.

Water: This liquid provides a perfectly diluted solution and base for the other ingredients.

Now that we know what is in Drano, let’s take a look at how it works.

How Does Drano Work?

Drano works by using the power of these ingredients to break down drain clogs in your home’s pipes.

Drano contains sodium hydroxide, which is a caustic substance. This means that it can break down organic matter like hair and grease.

It does this by breaking the bonds between the molecules that make up these substances.

You can use Drano in your kitchen sink, bathroom sink, shower, or bathtub. There are certain well-known formulas, such as Max Gel Clog Remover and Crystal Drano that are fast-acting and powerful.

Drano is safe for most types of pipes, including PVC, copper, and galvanized steel. However, you should avoid using it on aluminum or stainless steel as it can corrode these materials.

You can buy Drano in a variety of forms, including liquid, gel, and crystals.

Drano is safe to use as long as you follow the instructions on the product label. You should never mix Drano with other cleaning products as this can create dangerous fumes.

What Harmful Chemicals Are in Drano?

Drano does contain some harmful chemicals, so it is important to use it safely. The most harmful chemical in Drano is sodium hydroxide.

This substance can cause burns if it comes into contact with your skin.

If you do come into contact with sodium hydroxide, be sure to wash the area with soap and water. You should also seek medical attention if the area starts to feel painful or looks red.

Drano also contains chlorine, which is bleach. This substance can cause irritation if it comes into contact with your skin or eyes.

It can also cause fumes that can be harmful if inhaled.

When handling Drano, be sure to wear gloves and keep children and pets away. You should also open windows and doors to ventilate the area.

Mixing Drano with other chemicals can also create harmful fumes. Never mix Drano with vinegar, bleach, or ammonia.

These substances can create a toxic gas that can be dangerous if inhaled.

What Is a Good Substitute for Drano?

If you are looking for a safe and natural alternative to chemical drain cleaners, there are a few options you can try:

Baking Soda and Vinegar

One option is to use baking soda and vinegar. These two ingredients can create a chemical reaction that will help to break down the clog.

To use this method, start by pouring a cup of baking soda down the drain. Then, add a cup of vinegar and let it sit for 5 minutes.

Then flush the drain with hot water until the clog is gone.

Boiling Water

Another option is to use boiling water. This method will work best if the clog is caused by grease or soap buildup.

To use this method, simply heat up water to near boiling temperatures and pour it down the drain.

Be sure to do this slowly so that the boiling water has time to break down the clog and doesn’t splash back up at you.


If the above methods don’t work, you can try using a plunger. This method will work best if the clog is caused by a blockage in the drain pipe.

To use this method, simply place the plunger over the drain and push and pull until the clog is gone.

Use Laundry Bleach

You can eliminate drain clogs with laundry bleach. Bleach is a strong cleaning agent that will quickly break down the clog.

To use this method, simply pour a cup of bleach into your clogged drains and let it sit for 30 minutes. Then flush the drain with hot water until the clog is gone.

This can create toxic fumes so be careful to ventilate the area well.

What Ingredients Are Found in Liquid Drain Cleaners?

Drain cleaners all have a combination of strong chemicals that are designed to break down clogs quickly. The most common ingredients found in drain cleaners are Hydroxide, Chlorine, and Sodium Chloride.

There may be small variations in the ingredients depending on the brand, but these are the most common.

These common ingredients are used because they are effective at breaking down clogs, but they can also be dangerous. That is why it is important to use a liquid plumber safely and according to the instructions on the product label.

Does Drano Have Bleach in It?

Yes, Drano does have bleach in it. Chlorine is one of the main ingredients in Drano.

This ingredient helps to break down the clog and is also effective at killing bacteria.

Bleach can be dangerous if it comes into contact with your skin or eyes. It can also create harmful fumes if inhaled.

Make sure to use your Drano Max Gel properly to avoid any issues.

Is Drano the Same as Bleach?

While Drano contains bleach, it is not the same as bleach, because Drano also contains other ingredients.

Drano is a chemical drain cleaner that contains a variety of powerful ingredients. They work together to break down the clog quickly.

Bleach is a household cleaning product that only contains chlorine. Chlorine is effective at breaking down the clog and also kills bacteria.

However, it doesn’t have the full range of ingredients that Drano has and therefore may not guarantee that your clog dissolves.

Does Drano Max Have Bleach in It?

Drano Max Gel is a powerful drain cleaner that contains a variety of ingredients, including bleach.

This product is designed to quickly break down the toughest clogs. It is also effective at killing bacteria and preventing bad odors. Use it when you have standing water in your tub or sink, or a slow draining sink.

Since this product contains bleach, it’s important to ventilate the area when working with Drano Max Gel, since it may drain slower with tougher clogs.

Final Thoughts

Drano can be a powerful tool for clearing clogged drains, but it’s important to use it safely. Understanding what ingredients are in Drano can help you use it more effectively and safely.

Just follow the directions and your experience with this popular household product will be smooth sailing.
