I’ve been buying this product for around 5 years now, and that says a lot on its own. It has been a reliable part of my laundry routine for a long time and I keep coming back to it because it works well. It gives clothes a fresh, clean smell and adds that extra feeling of hygiene, especially for items where you want more than just a normal wash. The Fresh Cotton scent is pleasant without being too strong, and the large pack size is very practical as it lasts well. What I like most is the consistency. Some products are fine at first and then you switch, but this is one I’ve kept buying over the years because it does exactly what I need it to do. Having the larger multi-pack is also convenient and good value if you use it regularly. Overall, a very reliable laundry product that I’ve trusted for years and would happily keep buying — definitely 5 stars.

I originally bought Dettol Antibacterial Laundry Cleanser for basic hygiene peace of mind, but it’s become one of the most versatile and quietly effective products in my entire cleaning setup. I’ve tested it extensively for over a year across dozens of everyday and off-label scenarios—especially anything involving sweat, bacteria, or damp fabrics—and I always keep it in stock. I primarily use the Fresh Cotton version, which leaves behind a clean but not overpowering scent that’s suitable even for gym clothes or more sensitive skin. My most frequent use is gym-related: I’ll drop gym shorts, trunks, gloves, and even socks into a bucket with a diluted solution—about a capful to 2.5 litres of cool water—and let them soak for anywhere from 30 minutes to an hour. It’s a lifesaver for trainers and swim gear. Even when left damp overnight in a sealed bag, the clothes come out completely fresh, without that humid mildew smell you often get from sweaty synthetics. I’ve done soak tests at temperatures as low as 5°C in the garage during winter, and up to 20°C indoors in summer. Impressively, even at those low temperatures, it still kills odour-causing bacteria—confirmed through sniff tests and the total absence of lingering smells after air drying. The bottle claims 99.9% bacterial kill from 15°C onwards, but based on my testing, it’s performing even below that. I ran informal swab-and-culture tests using basic agar plates and found Dettol-treated fabrics had notably fewer bacterial colonies than untreated ones washed with detergent alone. The product is bleach-free and safe on colours, which means I’ve used it without hesitation on dark cottons, synthetics, sportswear, and even wool blend socks with zero fading or texture change. It’s not just laundry, either. I’ve used it to sanitise travel pouches, canvas tote bags, pillowcases, hand towels, and even reusable nappies and kitchen cloths. When I want to stretch its value, I reuse the soaking solution once or twice for similarly dirty loads (like socks or gym towels), replacing the liquid after two rounds. This way, a 1.5L bottle goes a long way—at £2.26/litre, it’s cheaper than running hot washes and better for delicate items too. I've tested Dettol Antibacterial Laundry Cleanser across a wide range of real-life scenarios, and it consistently proves itself as one of the most versatile hygiene products in my routine. It’s been especially reliable with gym shorts made from synthetic or polyester materials, which often hold onto odours. I also regularly use it for swimming trunks and Speedos—items that are frequently damp and stored in sealed bags. Trainer liners and shoe insoles benefit from a soak as well, coming out noticeably fresher even after just 30 minutes. Cotton socks and bamboo socks, which can get particularly sour after long days or workouts, respond well to both short and overnight soaks. My work shirts, especially under the arms, also come out fresher and less prone to developing lingering smells over time. Pillowcases and duvet covers used during colds or flu are another prime use—Dettol gives added reassurance that everything's properly sanitised. I also use it on cotton boxers and briefs without worrying about damaging the fabric. For travel and gym routines, it handles laundry bags and tote bags excellently. Even wipe-clean canvas pouches that gather sweat and grime respond well to a quick soak. Sweat-drenched running tops and yoga towels get deodorised and disinfected easily. Kids’ uniform polo shirts, which can carry that musky scent after a long day, come out noticeably cleaner too. Kitchen dishcloths and face towels left damp in baskets for a day or two lose their funk entirely. Fabric shower caddies that build up mildew over time are another great use case. Finally, Dettol is especially effective with reusable baby wipes and reusable nappies (particularly the outer wraps). These are the kinds of items where sanitisation really matters, and this product handles them gently yet thoroughly. From these experiences, the pros are clear. It genuinely works at low temperatures—I’ve tested it between 5°C and 20°C, and it still cuts through bacteria and smell. It doesn’t fade colours or damage delicate fabrics. It’s incredibly versatile—you can use it in a machine, for a hand soak, or even leave items in a bucket overnight. The “fresh cotton” scent is clean and subtle, not chemically or artificial. You can reuse the soak solution once or twice for similarly dirty items, which adds a cost-effective edge. One bottle stretches surprisingly far when using 1–2 capfuls per cycle or soak. That said, it’s not perfect. Cons include the fact that bulk bottles can sometimes leak slightly if stored on their side. There’s also no child safety cap, which is something to consider if you’re soaking items in open buckets. It’s not a replacement for detergent—it sanitises, not cleans—so you still need to wash properly. If you use it for daily soak routines, you'll go through bottles quicker than expected. Also, repeated exposure can mildly dry your skin, especially if you're soaking things by hand often without gloves. Bottom line: this is a practical solution for anyone dealing with sportswear, kids' clothes, work uniforms, or just wants to reduce bacteria and odours without blasting everything at 60°C. If you're a gym-goer, traveller, cyclist, or anyone who sweats a lot and washes on cold, this is a staple. If you only wash at 60°C+ and don’t have odour or hygiene issues, you likely don’t need it—but even then, it's a nice insurance policy during flu season or post-illness.

The scent is a bit strong. This is great for bedridden patients laundry. It helps remove any urine scent from their bedding so they can sleep well and properly

The biggest question you’ll ask yourself if you’re researching this product is “Is this a scam?” or “Do I actually need to sanitise?”, because I went through the same process too. From what I’ve learned, it isn’t a scam. Your washing machine and detergents are designed to remove germs and dirt, but not to sterilise or "kill everything" (google it). It’s usually the higher temperatures of 60 °C and above that kill most of the remaining germs. But personally, running 60 °C+ washes tends to shrink my clothes, so I use this sanitiser which makes me more comfortable running cold and 30 °C washes. I’ve now gotten into the habit of using it for almost everything because why not, and it’s actually pretty cheap in this deal where you get 6L worth. It also smells good and gives my laundry a consistent scent, probably because it advises you add it to the fabric softener drawer, which comes in during the final rinse before the spin. I’ve noticed this especially because I actually have two different detergents that I switch between depending on what I’m washing (for example, clothes vs towels and other bits and bobs). 2 caps full in the fabric softener draw and you're set. I recommend this product, especially during flu season.

If you’ve ever pulled a "clean" load of laundry out of the machine only to find it still has a faint, lingering musty smell, you need this. The Dettol Laundry Sanitiser in Fresh Cotton has officially become a permanent staple in my laundry room. Why I’m obsessed: • Actually Kills Bacteria: I do a lot of cold washes to save energy and protect my clothes, but cold water doesn’t kill germs. Adding this gives me peace of mind that my gym clothes and towels are actually sanitized, not just "scented." • The "Fresh Cotton" Scent: It’s light, crisp, and smells like clean luxury. It’s not overpowering or "chemically" like some disinfectants—it just smells incredibly clean. • Goodbye, Lingering Odors: It works miracles on those stubborn smells in synthetic fabrics (looking at you, yoga leggings) that regular detergent seems to miss. • Easy to Use: You just pour two caps into the fabric softener drawer. It’s a seamless addition to the routine. • Gentle on Fabrics: I’ve used this on everything from delicate bedsheets to heavy towels, and I haven’t noticed any fading or damage to the fibers. My Routine: I pair this with a fragrance-free detergent. This way, the Fresh Cotton scent really shines through without competing with other floral or soapy smells.

I get through so much of this as I have dogs, one being a puppy so for accidents, just washing their bedding or the sofa covers it give me peace of mind using a laundry sanitiser. Buying like this in a pack, you get fantastic savings!

Cuts through odours brilliantly and leaves laundry smelling properly clean without being overpowering. Great for gym gear and towels, and the 6L pack lasts ages. A simple way to keep everything hygienic.
