The Only 2 Homemade Drain Cleaner Recipes You Need to Know

A partially blocked drain might seem harmless at first, but it doesn’t take long before your shower turns into a mini bath and your sinks start draining at a snail’s pace. Slow‑moving drains are more than just annoying, they’re often the first warning sign of a deeper plumbing issue that can escalate if ignored. Most people instinctively reach for a store‑bought chemical drain cleaner to dissolve hair, grease, or soap scum. But harsh chemical cleaners can corrode your pipes, damage seals, and create bigger plumbing problems down the track. Before calling a professional, try these two simple and effective homemade drain cleaner recipes. They’re gentle on your plumbing, safe for your home, and surprisingly powerful.

1. Baking Soda & Vinegar DIY Drain Cleaner

If you’ve spent any time on TikTok, you’ve probably seen the viral bicarb soda and vinegar drain hack. It’s popular for a reason, it works. This natural drain cleaner uses a classic acid‑base reaction to break down grime, deodorise your drain, and help shift minor blockages without damaging your pipes.

What You’ll Need

• 1 cup baking soda
• 1 cup white vinegar
• 1 pot of hot water (not boiling)
• Drain plug or duct tape

Time required: 15–30 minutes

Step‑by‑Step Instructions

Step 1: Run the hot tap for a minute or two. This softens and melts fats, oils, and grease that may be contributing to the blockage. Step 2: Pour 1 cup of baking soda directly into the drain. Step 3: Add 1 cup of vinegar. The fizzing reaction helps loosen debris stuck to the drain walls. Step 4: Cover the drain with a plug or duct tape to keep the reaction contained. Step 5: Let the mixture sit for 10–30 minutes, depending on how stubborn the blockage is. Step 6: Slowly pour hot (not boiling) water down the drain to flush everything through. Boiling water can warp or damage PVC pipes. Step 7: Repeat if needed. This method is safe enough to use regularly as a natural drain deodoriser.

2. Hot Water & Detergent Drain Cleaner

No bicarb or vinegar? No worries. This simple hot water and dishwashing detergent method is perfect for breaking down grease‑based blockages. Detergents contain surfactants, ingredients designed to lift and dissolve oils—making this a great DIY alternative to chemical drain cleaners.

What You’ll Need

• 1 pot of hot water
• 2 tablespoons of dishwashing detergent

Time required: 5–10 minutes

How to Use It

Step 1: Mix 2 tablespoons of detergent into a cup of hot water.

Step 2: Pour the mixture down the drain.

Step 3: Run the hot tap until the bubbles stop coming through.

Step 4: Repeat if necessary. This method is especially effective for kitchen sinks or bathroom basins where oils, makeup cleansers, and skincare products often build up. It’s gentle enough to use weekly as a preventative measure.
