At GPS Gas Plumbing Services, we've seen our fair share of blocked drains across Sydney. While a severe blockage requires professional tools, we know that many homeowners first reach for a chemical drain cleaner for minor issues. To help you choose wisely, we've put our professional experience to use and reviewed some of the most popular drain cleaners available in Australia.
This guide will cover the features, strengths, and weaknesses of several leading products. We'll also touch on the common causes of clogs and explain when it's time to put down the bottle and call a professional.
Important Safety Warning
Before you begin: Chemical drain cleaners are powerful substances. Always wear protective gloves and eyewear, and ensure the room is well-ventilated. Never mix different drain cleaners (especially bleach and ammonia-based products), as this can create toxic fumes. If a chemical cleaner fails to clear the blockage, do not use a plunger immediately after, as you risk splashing dangerous chemicals onto yourself.
The 4 Most Common Causes of Clogged Drains
Understanding what causes a blockage is the first step in preventing one. Here are the main culprits we encounter:
- Food Particles: In the kitchen, scraps like coffee grounds, vegetable peels, and eggshells can accumulate in pipes. A simple sink strainer can make a huge difference.
- Grease and Oil: It's tempting to wash cooking grease down the sink, but this is a primary cause of stubborn clogs. As grease cools, it solidifies inside your pipes, trapping other debris.
- Hair: In the bathroom, hair is the number one enemy of drains. It tangles easily and mixes with soap scum to form dense clumps that are difficult to dislodge.
- Tissues and Hygiene Products: Flushing anything other than toilet paper can lead to serious plumbing problems. Wet wipes (even those marked "flushable") and paper towels do not break down easily and are notorious for blocking sewer lines.
What is the best drain cleaner in Australia?
As seasoned plumbers, we have evaluated countless products found on the shelves of Coles, Woolworths, and Bunnings. Here is our breakdown of the most effective options.
Drain Clean Hair Unclogger
We find this product highly effective for its specific purpose: dissolving hair clogs in bathroom drains. While it is marketed as containing biodegradable surfactants, it is still a chemical product that requires care.
- Pros: Fast-acting formula designed specifically for hair and soap scum. Safe for PVC and metal pipes.
- Cons: Ineffective against grease or solid objects. Strong chemical odour requires ventilation.
Orange Power Sticky Spot and Goo Dissolver
While not a traditional caustic drain opener, we recommend Orange Power for kitchen maintenance. It excels at breaking down sticky, greasy residues using natural citrus oils rather than harsh hydroxides.
- Pros: Cuts through grease and fat buildup effectively. Versatile for other household cleaning. Smells like citrus rather than chemicals.
- Cons: Not potent enough for complete, compacted blockages or hair clogs.
Easy Off Drain Cleaner Turbo Gel
From our professional experience, Easy Off Turbo Gel is a versatile all-rounder. Its thick gel formula cuts through standing water to reach the clog, making it a go-to for standard household blockages.
- Pros: Begins working in minutes. Heavy gel sinks through standing water to attack the blockage directly. Suitable for both kitchen and bathroom.
- Cons: Highly caustic formula requires strict safety adherence (gloves/glasses). Not a solution for tree roots.
Drano Bathroom Max Gel
This product is engineered to tackle clogs in bathroom sinks, showers, and tubs. The formula is specifically balanced to dissolve hair and soap scum.
- Pros: Targets tough hair clogs effectively. Safe for metal and plastic pipes when used as directed.
- Cons: Corrosive product; handle with care. Do not use in toilets, garbage disposals, or washing machines.
Drano Kitchen Crystals
This granular formula is made for kitchen sinks where grease and food waste are the primary issues. The crystals heat up when mixed with water to melt away tough grime.
- Pros: Highly effective on grease and food-based clogs. Safe for septic tanks.
- Cons: The heat reaction can be vigorous; handle with extreme care to avoid splashing. Absolutely not for use in toilets.
BOSTON Drain Refresh Eco Enzyme
For those seeking an environmentally friendly option, this enzyme-based cleaner is a great choice. It uses bacteria to "eat" organic matter, making it safer for homes with children and pets.
- Pros: Non-toxic, eco-friendly, and safe for regular maintenance. Controls odours naturally.
- Cons: Works much slower than chemical cleaners (often requires overnight application). Cannot clear total blockages instantly.
BOSTON Drain Away Heavy Duty
Often found in the hardware aisle rather than the cleaning aisle, this is a high-strength sulphuric acid-based cleaner designed for severe organic blockages.
- Pros: Extremely potent against hair, grease, and organic matter. Sold in bulk sizes (5L) for frequent issues.
- Cons: Very dangerous if mishandled. It can cause severe chemical burns. Not eco-friendly.
When to Call a Professional Plumber
If a chemical cleaner doesn't solve the problem, or if the blockage quickly returns, you likely have a structural issue or a foreign object in the line. At this point, it’s crucial to contact a licensed plumber. Continuing to use chemicals can corrode your pipes and mask the underlying cause, leading to costly damage.
At GPS Gas Plumbing Services, we have the professional equipment (such as CCTV drain cameras and water jetters) to identify the source of your blockage and clear it safely.
Conclusion: Which Cleaner Wins?
The "best" cleaner depends entirely on your specific situation:
- Best All-Rounder: Easy Off Drain Cleaner Turbo Gel is reliable for both kitchen and bathroom clogs.
- Best for Kitchen Grease: Drano Kitchen Crystals or Orange Power.
- Best Eco-Friendly Choice: BOSTON Drain Refresh is excellent for maintenance and odour control.

Frequently Asked Questions
Can I use chemical drain cleaners in the toilet?
Generally, no. Most chemical cleaners generate heat or use caustic agents that can crack the porcelain of the toilet bowl. Additionally, the volume of water in the toilet trap often dilutes the chemical too much to be effective. For toilets, a plunger or a plumber's auger is the safest method.
Do enzyme drain cleaners really work?
Yes, but they require patience. Unlike harsh chemicals that burn through clogs in minutes, enzyme cleaners use bacteria to eat organic matter over several hours or overnight. They are excellent for maintenance and removing bad smells but may not clear a fully blocked drain instantly.
Will drain cleaner damage my plastic (PVC) pipes?
Most modern liquid drain cleaners are formulated to be safe for PVC pipes if used according to the instructions. However, crystal-based cleaners can generate significant heat; if used in excess, this heat can soften or warp plastic pipes. Always stick to the recommended dosage.
