Buyer’s Guide

Different drain cleaners have different functions. Before making a purchase, consider these factors to determine which one is right for your needs.

Cleaner Type

Cleaners can either be a substance or a stick that you put in your drain.


There are three types of formulas used to make liquid or powder drain cleaners.

  • Acidic: Acidic cleaners are effective at unclogging blockages caused by toilet paper, hair, grease, food, or similar items. However, they don’t work well in older plastic, steel, or aluminum pipes.
  • Caustic: Caustic drain cleaners are good for removing food, grease, and soap scum from sinks or showers, but they’re not effective in toilets. They’re not recommended for use in pipes older than 20 years either.
  • Enzymatic: Enzymatic cleaners work best when they’re used monthly to prevent clogs from ever forming. Since they typically have non-toxic ingredients, safety equipment isn’t required when you’re using them.


Drain snakes are long sticks made of plastic or metal that feed into your drain. They usually have hooks or brushes along their bodies to capture the hair or other debris that’s causing the clog.

Blockage Location

Different areas of the home typically require different types of drain cleaners. Some may be better for sinks and tubs, while others work better for toilets. Be sure the drain cleaner you choose can handle the clog you’re trying to tackle.

Clog Type

Food, hair, paper, grease, plastic, soap scum, and even household items, such as pet toys, are some of the materials and items that can get stuck in your drains. Ensure that the drain cleaner you’re purchasing is appropriate for what’s causing your blockage.

Frequently Asked Questions

What are the signs of a clogged drain?

Some common signs include:

  • Slow water drainage
  • No water drainage
  • Gurgling sounds
  • Bad odors

Are there any DIY options to unclog a drain?

Although drain cleaners are relatively affordable and accessible, if you’re in a pinch and need to unclog your drain, there are some DIY methods you could try. Pouring boiling water down the drain is a popular option, but it’s largely ineffective and could be bad for your pipes. Some people also use baking soda and vinegar, but these materials will only work on small clogs.

What safety measures should I take when I’m using a drain cleaner?

If you’re using an enzymatic drain cleaner or drain snake, you don’t need to take any safety precautions. With the other two types of cleaners, wear gloves and safety goggles to keep them from coming into contact with your body.
