A blocked sink is one of the most frustrating household problems—water pools in the basin, drainage slows to a trickle, and unpleasant odors start to develop. Whether it’s the kitchen or bathroom sink, clogged drains are often caused by grease, soap scum, food scraps, or hair buildup.

The good news? You don’t need a plumber to fix most blockages. With the right approach, you can quickly clear your sink drain using OzKleen Drain Power—a fast-acting, non-corrosive drain cleaner designed to dissolve tough blockages while being safe for pipes and septic systems.

In this guide, we’ll cover what causes sink blockages, how to use OzKleen Drain Power effectively, and key prevention tips to keep your drains flowing freely.

Common Causes of Sink Blockages

Sink blockages don’t typically happen overnight—they build up gradually as everyday substances accumulate in your pipes. Here are the most common culprits:

  • Foreign Objects – Accidentally dropping bottle caps, pieces of plastic, or small utensils into the drain can cause sudden and severe blockages.
  • Grease & Fat Buildup – Cooking oils, butter, and fatty food residues stick to pipe walls, solidifying over time and restricting water flow.
  • Food Scraps & Starchy Residue – Rice, pasta, coffee grounds, and eggshells don’t break down easily and can expand inside pipes, creating blockages.
  • Soap Scum & Hard Water Deposits – Over time, soap residue can combine with minerals from hard water, forming a thick, sticky layer inside pipes.
  • Hair & Personal Care Products – More common in bathroom sinks, hair can trap toothpaste, shaving cream, and other personal care products, forming tough clogs.

Step-by-Step Guide: How to Unblock a Sink Using OzKleen Drain Power

Drain Power 500ml

Unclogging your sink with OzKleen Drain Power is a fast and hassle-free process. Safe for all types of pipes and septic systems, it effectively dissolves grease, food debris, and soap scum without causing damage. Follow these steps for the best results:

Step 1: Remove Any Standing Water

If your sink is completely blocked and filled with water, use a cup or bowl to remove as much as possible. This ensures that the solution can directly reach the clog.

Step 2: Use a Drain Snake to Loosen the Blockage

Before applying the drain cleaner, insert a drain snake or a flexible wire into the sink drain to help dislodge any solid buildup. This can help break up hair, food scraps, and other obstructions, allowing the cleaner to work more effectively.

Step 3: Pour OzKleen Drain Power into the Drain

  • Shake the bottle well before use.
  • Slowly pour 250ml (half a bottle) directly into the sink drain. Avoid splashing or contact with skin.

Step 4: Let It Work for 15–20 Minutes

  • Allow the solution to sit for at least 15–20 minutes to break down grease, soap residue, and organic matter.
  • For tougher blockages, you can leave it for up to 30 minutes before flushing.

Step 5: Flush with Cold Water

  • Turn on the cold water tap and let it run for at least 30 seconds.
  • This helps to rinse away any dissolved debris and clear the drain completely.

Step 6: Repeat If Necessary

  • If water is still draining slowly, repeat the process using the remaining 250ml of OzKleen Drain Power.
  • For regular maintenance, use once a month to keep drains flowing smoothly and prevent future clogs.

OzKleen Drain Power is perfect for clearing clogs in:
? Kitchen sinks – Dissolves grease, food scraps, and oil buildup.
? Bathroom sinks – Clears hair, soap scum, and toothpaste residue.
? Shower & bathtub drains – Removes hair and body care product buildup.
? Toilet drains – Helps clear minor blockages and keeps pipes clean.

Alternative DIY Methods (If You Don’t Have a Drain Cleaner)

If you don’t have OzKleen Drain Power on hand, there are a few DIY methods you can try to unclog your sink. While these solutions may work for minor blockages, they often take longer and require more effort compared to a fast-acting drain cleaner.

1. Boiling Water Method

  • Boil a kettle of water and carefully pour it down the drain.
  • This can help dissolve grease and soap scum, but won’t be effective for hair or solid food blockages.

2. Baking Soda & Vinegar

  • Pour ½ cup baking soda into the drain, followed by 1 cup white vinegar.
  • Allow it to fizz for 10–15 minutes, then rinse with hot water.
  • This method is best for minor buildups but may not clear major clogs.

3. Plunger Method

  • Fill the sink with enough water to cover the plunger’s suction cup.
  • Position the plunger over the drain and plunge vigorously for 20–30 seconds.
  • Works best for loosening blockages caused by food debris.

4. Drain Snake or Wire Hanger

  • This is effective for physical obstructions like hair clogs but won’t dissolve grease.
  • Insert a drain snake or unraveled wire hanger into the sink drain.
  • Move it around to break up hair and debris.

How to Prevent Sink Blockages

Preventing sink blockages is much easier than dealing with a clogged drain. A few simple habits can help keep water flowing smoothly and reduce the need for frequent drain cleaning. 

For the kitchen sink, a sink strainer is an easy way to catch food scraps, hair, and debris before they enter the pipes. Also avoid pouring grease or oil down the drain, as they solidify and create stubborn clogs—instead, collect grease in a container and dispose of it in the trash. Continue to be mindful of what goes down the sink—coffee grounds, pasta, and rice expand in water and can easily cause serious blockages. 

To prevent buildup in the bathroom, flush your drains with hot water weekly, which helps break down soap scum and minor grease accumulation before it becomes a problem. For long-term drain maintenance, using a drain cleaner solution once a month helps dissolve lingering residue and prevents future clogs. By following these simple steps, you can avoid costly plumbing repairs and keep your drains running efficiently with minimal effort.

Blocked sinks are a hassle, but you don’t have to waste time with ineffective DIY methods or expensive plumbing services. OzKleen Drain Power provides a fast, powerful, and safe solution to remove tough blockages in just 15–20 minutes.

FAQs

What should I do if my sink is completely blocked?

If water isn’t draining at all, remove standing water first, then apply OzKleen Drain Power and let it sit for 30 minutes before flushing with cold water.

How do I know if my drain is partially blocked?

Signs of a partial blockage include slow drainage, gurgling sounds, water pooling in the sink, and unpleasant odors coming from the drain.

Can I use boiling water to unblock a drain?

Boiling water can help dissolve grease and soap scum, but it should be avoided if you have PVC pipes, as extreme heat can soften or damage them. For minor blockages, hot (not boiling) water can be effective.

Is it safe to use chemical drain cleaners?

Many chemical drain cleaners contain harsh, corrosive ingredients that can damage pipes over time, especially if used frequently. They can also be hazardous if inhaled or if they splash onto the skin. Safer alternatives, like enzymatic or non-corrosive drain cleaners, are recommended.

How can I tell if a blocked drain is a sign of a bigger plumbing issue?

If multiple drains in your home are backing up, toilets are gurgling, or water comes up from one drain when another is used, it may indicate a main sewer line blockage that requires professional plumbing assistance.
