What Should You Consider When Buying A Drain Cleaner?

1. Type of Cleaner

There are three main types of drain cleaners that we'll look at below. However, before you settle on the cleaner you want, ensure that you know what type it is to know when and where to use it. Whether you want cleaners to use on your kitchen sink, bathroom, or garbage disposals, knowing which one works for your clogged drain will be a big help.

Check the product description if you're not sure what type it is. Once you chose your chemical drain cleaners, you can now get to work.

2. Budget

We've looked at several cleaners. While some cleaners are more affordable than others, you can be sure that you'll get what you're looking for at your budget. Don't go breaking the bank in a bid to get the best clogged drain cleaner for your drains.

Liquid Plumr and the other cleaners we've looked at today are all very efficient. However, we want you to get the best drain cleaner on your budget.

3. Amount

For most of these cleaners, you'll need to pour the whole bottle or half the bottle down the drain. Therefore, depending on how many clogged drains, you may need to get more than one bottle. Choose the best drain cleaner that will be enough to cater to all your needs.

What Are the Types of Drain Cleaners?

Before we dive into the types, it's important to check your home inspection report to determine the type of drain you have.

Let's dive in.

1. Enzymatic Drain Cleaners

These cleaners contain interesting enzyme-producing bacteria such as bacillus that often feed on clogs. These cleaners work best when used every month. They will prevent clogs and clear any existing clogs.

These drain cleaners work best on some soft matter like paper and hair. They are unsuitable for tougher materials like soap scum or grease. Expect these cleaners to take about 24 hours to kick in.

An advantage of these cleaners is that they are gentle and non-corrosive. As a result, you can safely use them on metal and older plastic drain pipes in showers, sinks, tubs, and toilets. In addition, you don't have to use protective wear while working with them as they are free from skin/eye irritants and harmful toxins.

2. Caustic Drain Cleaners

These drain cleaners are made from alkaline chemicals such as sodium hydroxide. You can use these cleaners to remove grease, food, and soap scum. These cleaners work by converting any clogged material in the drain into a soap-like substance that dissolves under any plain water.

You can expect these cleaners to work within 30 minutes. However, note that these cleaners don't work great in toilets as they aren't suited for paper materials. However, these cleaners will work well if your pipes are made of plastic or metal, such as copper or stainless steel.

Don't use them if your pipes are made of plastic and are more than 20 years old. These cleaners are less toxic than acidic cleaners, which we'll look at below. However, they are not as safe as our previous type and can irritate your eyes and burn your skin.

Therefore, wear safety glasses, cover your skin, and wear a respirator when using them. In addition, ensure that the gloves you use are made of chemical-resistant materials such as butyl.

3. Acidic Drain Cleaners

Our final type is these cleaners that are the most powerful of the bunch. These cleaners are made of hydrochloric acid and sulfuric acid. These can clear soap scum, grease, food, hair, and any paper-based clogs. Within 15 minutes, you can expect your drain to be fully open.

You can use these cleaners in newer metal or paper-based pipes for your shower, tub, sink, and toilet drain. However, avoid using these cleaners on older metal or plastic pipes, especially stainless steel, galvanized steel, or aluminum chrome.

Use safety gear while you handle these cleaners. Safety glasses, respirators, skin-covering clothing, and gloves are a must.
