Best Kitchen Sink Unblocker Products in the UK
1. Domestos Sink and Pipe Unblocker
Domestos is a tried and tested brand when it comes to cleaning products, and that reputation is solidly upheld when it comes to their sink and pipe unblocker.
This product is advertised as being at least twice as efficient as other similar products and that it takes only 15 minutes to completely clear any blockage in your kitchen sink. In addition to unblocking the pipes, this product will also kill off any germs that may have been accumulating in the drain.
Sink blockages tend to also give off an unpleasant odour, but Domestos’ sink and pipe unblocker will also eradicate any lingering scents coming from the troublesome blockage.
This product is both affordable and safe to use in toilets and showers, as well as with septic tanks.
2. Mr. Muscle Drain Unblocker
Mr. Muscle’s Drain Unblocker is known for swiftly dissolving even the toughest of drain blockages.
For best practice, use this product on a weekly basis on the drains throughout your house, not just in your kitchen. When there is a specific blockage, pour the entire bottle down the drain and leave for a full five minutes before flushing it with piping hot water.
3. Buster Kitchen Plughole Unblocker
Buster Kitchen Plughole Unblocker is known for targeting fat and food that may have built up in your kitchen drains. Instead of liquid, the bottle is full of crystals, all of which will need to be poured down the drain and left for 20 minutes before flushing with hot water.
This product is made in the UK and is also safe for use on septic systems.
Some users have mentioned some smoke coming from the drain as the product dissolved, as well as strong fumes that had a pungent smell.
Other users also mentioned melting damage to the areas around the drains, although this could potentially be caused be leaving the product longer than advised before flushing out with hot water.
4. Scotch Corporation Instant Power Hair & Grease Drain Opener
Scotch Corporation’s Drain Cleaner and Opener has a particular talent for targeting clogs caused by hair and grease. It creates heat as a way to swiftly eradicate the buildup of grease in your kitchen drains.
For best results, this product should be left in the drain overnight so that it can properly dissolve the blockage.
It’s advised to wear safety goggles when using this product and to try to remove any standing water from the sink before adding the product. Only two to four cups are required but it’s still important to flush the pipes with hot water after waiting the appropriate amount of time.
5. Duzzit Drain Away
It creates a cleaning foam that will eat through any pesky blockages in your pipes. It’s also safe for non-metal pipes, so if there is plastic in your shower or sink drains then you can use this product without a second thought.
This is one of the more affordable products on the list, is highly effective, and requires only one sachet to have visible results.
6. Spear & Jackson Heavy Duty Sink and Drain Unblocker
Spear & Jackson Heavy Duty Sink and Drain Unblocker is quick to act when getting into those particularly fatty kitchen sink blockages. It’s also effective in working through both soap and hair buildup in bathroom drains, as well as unblocking exterior drains.
It is advised to use this product as regularly as possible in order to ensure that no food, fat, hair, or grease can build up in those drains and cause a bad blockage. This may be hard to do when this product is in the slightly pricier bracket for drain openers.
Some users have mentioned that despite using an entire bottle of this product, their drains are not cleared as effectively as they would be after using other similar products.
7. HG Kitchen Drain Unblocker
HG Kitchen Drain Unblocker is unique in that it is fully biodegradable and uses natural enzymes and microbes to offer a safer alternative to this type of product. It is also safe for all drains, as well as septic tanks.
In addition, it increases your septic tank’s bacterial culture and helps to prevent any blockages from occurring in your drains.
For best results, pour 300 ml of the unblocker into your drain along with an equal amount of lukewarm water. Leave the product for six to eight hours before flushing the drain with hot water.
Some users have said that this product may be somewhat less effective than similar products and that it can sometimes require up to two bottles before real results can be seen.

Sink Unblocker FAQs
Is a blocked drain an emergency?
It is safe to say that a properly blocked drain can be viewed as a plumbing emergency. This situation could leave you without a usable sink for an extended period of time, which could have detrimental effects on your physical and food-based hygiene.
What happens if you leave a blocked drain clogged?
If you leave your drain for too long with a proper blockage, it can cause pressure to build up inside your pipes, which could lead to the pipes eventually cracking or bursting.
This could create a much more significant and expensive problem that may be considerably harder to fix than simply unblocking your drain. It may also leave a smelly and unpleasant mess and could be very unhygienic and swarming with germs.
What do I do if I’ve tried one of these products and my drain is still clogged?
Your best option if you find that the at-home drain unblockers are not effectively clearing the blockage would be to call in the professionals! A plumber will know exactly what to do and should have the blockage sorted in no time at all.
