As such, a clogged sink not only creates trouble in your daily work but also creates unpleasant odors and damages your plumbing system.

How to Tell if Your Drain is Clogged with Grease

Check out my five pointers for when you can tell your kitchen sink is clogged with grease. 🚨

  • Slow drainage: The water in the sink will be draining very slowly.
  • Gurgling sounds: As the water pushes through the grease clog, it creates air bubbles that cause the gurgling sound.
  • Standing water: If the sink water is stagnant and doesn’t go down the drain, it’s probably due to grease.
  • Visible Grease Residue: Inspect the drain by removing the cover for greasy residue. Presence indicates accumulation.
  • Disliked odor: A steady, oily smell that does not go away, even after cleaning, is a big sign of grease clogging.

If you notice any of the signs mentioned above, you need to deal with grease clogs.

So, here I have given you a step-by-step DIY method on how to unclog grease from the kitchen sink so you can solve it yourself.

Can You Put Degreaser Down the Drain?

No, definitely you can not put degreaser down in your kitchen sink drain. ⛔️

Here, I give you three points on why not to use a degreaser:

  • Clogs: Grease can dissolve, but it then solidifies, causing poor clogs.
  • Environment: Harsh chemicals harm beneficial bacteria in septic systems and wastewater treatment plants. ❌
  • Pipes: Degreasers can damage or corrode your pipes, leading to costly repairs.

But if you use the Drainout Cleaner I recommend above, it won’t harm your kitchen drainage and septic system.

It is beneficial to use the steps I showed you above rather than using a degreaser that is an environmentally friendly degreaser system.
