Clogged Kitchen Sink Home Remedy (6 Easy Methods) (2022)

Have you noticed your kitchen sink giving off a foul odor or the water draining slowly? If so, you may have a clogged kitchen sink. Then, you may wonder, what would be the most effective home remedy for a clogged kitchen sink? Truth is, there are many. In this article, we listed 6 home remedies to unclog a kitchen sink that you can do it by yourself and with tools you already have at home.

Common reasons for a clogged kitchen sink

Food residue: Food scraps are the most common reason for a clogged kitchen sink. Whenever you wash food down your kitchen sink, they may cause a blockage in the pipes and either stop water flow either completely or partially.

You’ll want to avoid washing down fruit skins, chicken bones, or flour into your kitchen sink. You should also never dispose of fibrous foods (fruits and vegetables) and starchy foods (pasta, potatoes, etc.) down the sink. These types of foods are difficult to break down and, as a result, will cause your kitchen drain to get clogged.

Tree roots: Thin tree roots may penetrate the joints of the pipes. When it grows over the years, your home’s entire sewage system may be compromised. If you’re lucky, the tree roots will only affect your kitchen plumbing, but it’ll still cost a hefty fee as you’ll need to call a professional.

Other solid matter: Long hair, crafting clay, paint, plastic, toothpicks, and other tiny everyday kitchen items may accidentally find their way into the sink drain.

Avoid this mistake when cleaning clogged kitchen sinks

You’ll want to avoid pouring boiling water down your kitchen sink. Boiling water will melt all grease, oil, and grime build-ups. But, boiling water will also melt PVC pipes, pipe sealants, and crack porcelain sinks. So while pouring boiling water into your sink once in a while is fine, you’ll want to avoid doing it regularly — daily pasta water, leftover soup, etc. This will cause permanent damages to your pipes and lead to costly pipe replacements.

For reference, here is a list of common water pipe materials and their heat resistance:

  • Iron – 2570° F
  • Copper – 1981° F
  • Galvanized Steel – 392° F
  • Pex – 200° F
  • CPVC – 200° F
  • PVC plastic – 140° F

As you can see, iron pipes (common in modern households) can withstand boiling water. However, the intense heat may weaken the sealants at the joints and cause water leakages.

  1. Pour the product into the drain

How to prevent your kitchen sink from clogging

The best home remedy for a clogged kitchen sink is prevention. There are many ways you can prevent sink clogs. Mainly, you’ll want to dispose of leftover food and cooking residues properly. In addition, you should avoid pouring the following things down the sink drain:

  • Grease, oil, and fat
  • Coffee grounds
  • Rice
  • Fruit skins
  • Starchy foods (pasta, rice, potatoes)
  • Fibrous vegetables
  • Flour

In other words, you should pour only clear liquids down the drain. Everything else should be disposed of accordingly.

Key takeaways

If you’ve tried everything, but your kitchen sink is still clogged, it means that there is a serious underlying issue. For example, tree roots that have penetrated the sewage system. Trying to fix these issues yourself is risky and could complicate things further. So, if all else fails, there’s no harm in calling in a professional.
