It has happened yet again; a drain in your house has become plugged up, again.

Whether it is your toilet or kitchen sink, this situation is annoying and you would rather not call the plumber.

Lucky for you, there are many products that claim to unclog your drains.

Two of the more popular and recognizable brands of drain cleaners are Drano and Liquid Plumber.

While both products may seem similar, there are differences that separate the two products from each other.


There are many similarities between Drano and Liquid Plumr. These similarities include:

  • Easy-to-follow directions
  • Both products are available in most stores
  • Both products usually under $20, depending on the store

Drano vs Liquid Plumr - Key differences

Despite the similarities, the products have differences as well.

  • Ingredients—While both Drano and Liquid Plumr share many of the same active ingredients, Drano has an active ingredient that is not in Liquid Plumr—sodium silicate.
    Sodium silicate is a chemical compound used for commercial purposes such as detergents, adhesives, and water treatment. Drano uses this ingredient to help clean drains, but sodium silicate turns into a liquid glass if it reacts with other chemicals
  • Products—Drano has a wider range of products compared to Liquid Plumr. While that is not a bad thing for Liquid Plumr, this range of Drano products allows people to try a product made specifically for his or her drain problem. Though Liquid-Plumr may lack having a range of products for specific situations, the few products from this brand are either the classic version or a pro-strength version that comes in many forms, mainly liquid or foam

  • Foam stabilizer
  • The gel version claims to be 50% thicker than its competitors


  • The different products of Drano Drain-cleaning solutions can cause the foam to form which may require cleanup.

 The great thing about Drano is that it is made to produce less foam compared to its competitors

If you have a problem with standing water, the gel version of Drano is great to use as the product claims that it is thicker. Whether that is true or not depends on perspective, but it’s worth a shot to see if it does work.

Since clogged pipes can happen anywhere in the house, it is great to know that Drano has different products that can help you.

Kitchen sinks and toilets, as we all know, are two of the most common systems that always seem to back up. Having a product that is designed to clean the pipes of these two systems is amazing for those who do not want to call a plumber.

As stated earlier, Drano contains sodium silicate which is known for being a liquid glass, and certain types of chemicals are known for reacting with sodium silicate. So, if you have used other pipe-cleaning products right before using Drano, it can cause this reaction to happen.

PVC pipes cannot handle Drano due to the liquid-glass reaction. If you have PVC piping do not use Drano as it will do more damage to your pipes. 

For PVC pipes, it's recommended to use a drain snake when possible. What is a drain snake and how do you use it? Find out more in our drain snake guide.

  • Safe for all piping types—Because Liquid-Plumr does not contain sodium silicate, it is safe to use for all types of pipes. It does not matter if your pipes are metal or PVC, Liquid-Plumr can clean and unclog them all.


  • Chemical smell

Always read the back label and instructions

Reading the label on the back of product where the instructions are located is quite obvious, but some people do not do this. Reading any instructions and warnings are important since there are many dangers of using both Drano and Liquid-Plumr.

These dangers include:

  • Health hazards
  • Hazardous gasses
  • Danger to your pipes

If you use too much of either product, there is a chance that you might actually damage your pipes.

This is especially true if you use Drano due to the sodium silicate.


Always read the instructions of the product to know and use the right amount of the product to use.

There are many health hazards associated with using Drano and Liquid-Plumr.

Both products are poisonous, it is dangerous to come into direct contact with it; if it touches your skin or splashes your eye, it can burn you.

You should read the first-aid directions on the product to know what to do if the product gets on your skin or eyes.

Hazardous gasses are created when you mix either product with different chemicals such as ammonia. It is important that you do not use two different drain products at the same time because hazardous gases will be produced.

Choosing between Drano or Liquid-Plumr

If you want a cleaner that is safe for all pipes and general use, you should probably pick Liquid-Plumber.

However, if you want a product that is for a specific use, you should buy a Drano product. For example, if your kitchen sink is backed up, you can use Drano Kitchen Sink.

The kitchen sink Drano is specifically made for this situation and is a great substitute for Liquid-Plumr.

The two products are similar, but you should decide which product you want to use for your drain problem.

Please remember from above, you should not use Drano and Liquid-Plumr at the same time since it can cause a hazardous gas to form.

Despite the fact both Drano and Liquid-Plumr are similar, Drano has an extra active ingredient that differentiates it from Liquid-Plumr.

While there are many pros and cons to both products, it is up to you to decide which product is best for you.

But if you are not sure if you should use either product, then it’s best to call the plumber.
