4.69 out of 5 – Kidspot mums would purchase Dettol Glen 20 Surface Spray again and recommend it to their friends and family.
With the onset of autumn, sunny and warm days that allow you to open up doors and windows to keep the home fresh start to dwindle. Wet and colder weather brings dampness, rain-soaked pets, muddy sports uniforms, and dirty work gear – and the odours that come with them! Luckily, Dettol are here to help with their ultimate in germ-busting freshness!
Fast and effective, Dettol Glen 20 Disinfectant Spray is easy to use and cares for your family by killing 99.9% of germs* and viruses** on hard and soft surfaces that you come in contact with every day, such as door handles, bins and toilet areas. It also eliminates odour-causing bacteria, leaving your home smelling wonderfully fresh.
Dettol Glen 20 is fast, easy to use and effective at:
- Killing 99.9% of germs and viruses on hard and soft surfaces.
- Killing the source of mould allergens and controlling the growth of mould and mildew on hard surfaces.
- Eliminating odour causing bacteria to leave your home smelling fresh and clean. Dettol Glen 20 “gets to the source” of the odour without heavy perfume and eliminates damp musty odours in areas where air does not circulate. Ordinary non-germicidal sprays can’t do this.

Thanks so much for this wonderful product to trial. I have used it for all sorts of things but it is especially good for freshening up the carpets, pet areas, curtains and anywhere else where bacteria tend to breed and create odours. I received the crisp linen and found that the fragrance tends to linger longer than a standard perfume which is great as it continues to maintain freshness well after it is sprayed. I will definitely be purchasing again.
Thank you. I received my product yesterday morning and put it to use straight away.
I cleaned my kitchen (was great to help get rid of cooking smells) and my bathroom with it.
Thankfully the smell of the spray isnt to overpowering like other sprays can be.
I also used it to spray my rubbish bin and i noticed a difference straight away.
I will continue to use the product over the coming days and comment further.
I love the fact that this spray kills 99.9% of germs and deals with mould and mildew which will be handy in the next few months. It has a pleasant smell and is quick and easy to use. I use it in the rubbish bin (just squirt and walk away). The toilet is another great place to use it and gives peice of mind that it will leave it germ free and smelling fresh.
Thanks for letting me trail the dettol glen 20.
I loved the smell of fresh linen as it was not a strong in ya face smell.
Works great in the bathroom or toilet as a air freshener.
Have also used it to spray the cats bed so it’s nice and clean and smells good.
Is easy to use and comes out as a even spray would recommended this product and happy to buy
Thanks received my trial product in crisp linen ,I loved the fragrance ,very subtle but yet you know it’s there ,which is what I like not over powering .
I used the product freely ,cleaned my toilet ,door handles ,the rubbish bin and just generally sprayed around my home ,so everything smells lovely in my home just now .
I would recommend ventilation when using as It felt like I breathed it in ,not such a good thing .
Not sure I would like to use on my pillow for that reason .
It does appear to be a very versatile product which can be used effectively in many areas and on many things which makes it good value for money .
The spray works well ,I would be keen to purchase again ,depending on the price ,if it’s cost effective and how long it lasts ,only drawback is how does one know it actually delivers and does what it says it does .
One just has to have faith in the product which I’m prepared to do ,as I’m a bit of a clean freak I like the thought of keeping my home as germ free as possible .
I love using this as a cleaner for the toilet as so quick to do ,also doesn’t leave streaks on the cover like other products I use .
Thanks kidspot and dettol. Have recieved this in crisp linen and have tried in it various places all over the house. The smell is strong but ita a nice smell and doesnt smell artificial. It actually smells like fresh linen 😁 will be buying this is future as can feel the difference in the house since using it. I am a clean freak and with a new bub its gotten worse but this has been a real gem
I’ve received the Fresh Linen Glen 20 spray and tried it immediately on the rubbish bin. It smells amazing. Everytime I walk past the bin, I can still smell it. I’ve sprayed my kids stinky shoes as well and the odour was gone immediately, I could only smell the lovely smell of Glen 20. I will definitely continue to buy this product. Thank you so much for letting me review such an awesome product.
I got the Dettol spray in Fresh Linen and I love the scent of it! It is not too over powering of floral or any artificial smell. I used it everywhere especially the bathroom. It gave me an ease of mind knowing that it can eliminate odor and bacteria at the same time. My husband has been using it to remove odor from his shoes too!! I’ll buy it in stores after I’ve finish with this one!
Thanks i have just received dettol disinfectant. It smells really nice and fresh. Thank you very very much .
Thanks kidspot and Dettol. I have just received my Glen 20 spray to trial and as soon as I had unpacked it from the box I used it on my son’s (stinky) sandals as I saw on the can that it eliminates odours. Well it has certainly done the trick! Will keep trying it around the home and at work on my keyboard and desk which is often used by others when I’m not there.
Just received my Dettol Glen 20 spray in the mail today. I decided to give the whole house a once over – used it on the rubbish bin, bath/shower + sinks (after I’d cleaned them with my normal bathroom cleaner), walls of bathroom where mould was starting to grow, bathroom mat, shower curtain, toilet and curtains of the whole house. Has a fairly pleasant smell but I would recommend good ventilation as it is quite strong and ‘chemical smelling’ like most cleaning products. I think I’d probably use it once a week when I do my normal housework and then more often when someone is unwell (on door handles, TV remote, ‘hot spots’ etc.) I like the satisfaction knowing that everything is clean and hygienic, especially with my four month old baby. Am excited to try it on the hallway carpet where my two big dogs like to sleep as the carpet absorbs their doggy smell.
Hi I would like to trial this as I have two dogs, I need to battle odor as well as protect my 3yr old and 10 week old from germs. I’m constantly spray and wiping everything which takes up a lot of time and I’ve been buying the scented ones to make my home smell nice
I would love to trial this product. I would use it when the kids are unwell and accidentally miss the toilet or don’t get there fast enough to kill germs and also kill the smell
The rubbish bin gets rather smelly so I would certainly use this is keep that smelly a whole lot better. Would also use in in the kitchen to keep surfaces clean
I would love to try this in my house, we have kids, pets, and farm animals so I’m pretty sure we must have a fair few germs floating around our house
Would love to try this especially since dettol is a trusted brand👍
I would use it on miss 3s potty and also door handled and taps now more germs are around.
I would use this on my daughter’s car seat , door handles and around the rubbish bins. Especially with are up coming new arrival I don’t want too many bugs around
I have 5 kids so theres plenty of room for germs to go around with 4 at primary school and 1 at kindy they are bound to bring them home..so id love to use it on the table, on their bags, shoes, kitchen tops and toilet
I would absolutely love to trial this product please with our busy household myself husband who is a joined and works on cars two teenagers and two younger kids plus two dogs life is busy this would be fantastic thanks
I would use this on all my taps door handles rubbish bins shoes light switches bathroom and kitchen surfaces I have a cat who likes to sleep anywhere bench and table included also 2 messy children one messy husband and a big messy dog I would love to know my home is germ free I hate bugs so if I can get rid of them its excellent
With a new bub due end of May this will come in super handy for newborn diaper bins as well as for my 3year old and the daycare shoe messes/odours I have to deal with!
I would use it to clean the benches down after my messy eaters as they graze all day 😂
Ohhh please! I have 3 kids and 2 cats who are all very dirty! I’d use this around the cats eating place, the toilet and I think it would be put to good use on the kitchen bench!!!
I would use this on the rubbish bins, my toddlers toys and handles of drawers and doors
Will love to try this out. With a house full of busy kids. I’m forever cleaning. I think this will be a welcomed addition 🙂
