1 thisisnot m.  · chemical warfare – it smells so horrible it should be used for chemical warfare
5 Sam  · absolute faith in Glen 20 – Even those on a budget, like myself, stick to products they believe are he best in their class - Glen 20 does it for me.
2 Harpoon  · What happened? – Used to be great. Now it leaves a foul taste in your mouth as soon as you spray it in a room or on a surface. Smells bad too. RIP Glen 20

This product has been used at my place of employment and it makes my head spin. Also, the advertising is disgusting and sexest and they portrait males to be absolutely clueless and complete idiots by using this product for snotty furniture. Disgusting marketing.

Glen 20 is now too expensive to buy – I have used Glen 20 for years and years. It's the best air freshener and I've tried them all. However the product is now grossly overpriced and I can no longer afford to buy it with the cost of living!!!!! Way too expensive now!! Show details

Great product – This product Glen 20 is one of the best in the market. It is anti bacterial not "kills the germs 99.9%". DO your study and you will see this is the best one on the market. Show details

I have used glen 20 my entire life. My father, a germaphobe, sprayed it religiously in the bathroom, on tv remotes, light switches, and our toys. My family have never had any adverse reactions ever. However, my husband has had severe allergic reactions to it. I was sick, and like my father, immediately went and bought a can of glen 20. My husband,… Read more

within a few minutes of me spraying it, experienced respiratory distress and broke out in bright red hives all over his body. At first, we didn't know what was causing the allergic reaction. When I realised it was the glen 20 I immediately checked the can to look for a list of ingredients and any allergy warnings, of which there were none. No information on the can at all about the ingredients and definitely no indication that it it could cause such a severe reaction. I tried searching online for more information, to which I found basically nothing. No information on allergic reactions. And the only ingredient I can find is ethanol, which I know for a fact would not cause this reaction in my husband as he works with ethanol based products at work with no such reactions. It is not the ethanol causing this. I have completely lost any and all trust I once had in this product, and will no longer be using to disinfect my home.

Glen 20 - the most toxic spray ever! – Someone in my household sprayed Glen 20 in the toilet several times daily. Every time I went in there I started coughing and it would end in gagging. I had flu-like symptoms (especially violent coughing) for 4 months before the can ran out and I could replace it with a straight eucalyptus spray. Then miraculously all symptoms disappeared. Also, it… Read more

stinks! It absolutely stinks and you can't seem to get the taste out of your throat. Glen20 is so toxic no-one should be using it and it definitely shouldn't be on the market!

Severe respiratory reaction to Glen 20 spray – I used Glen 20 Disinfectant Spray in my toilet to disinfect the area. I sprayed the product all over the toilet surfaces. **Adverse Effects Experienced:** Within minutes of using the product, I experienced severe adverse reactions, including: - Throat closure, making it difficult to breathe. - Tightness in my chest accompanied by pain and… Read more

discomfort. - Development of fever. - Blocked nose and runny nose.

These symptoms were alarming and required immediate attention. I do not have a history of using this product, and this was my first encounter with such severe reactions from a disinfectant spray.

- The product caused severe respiratory distress and allergic reactions. - Lack of clear warning about potential severe respiratory effects on the product label.

Very dangerous product – Very dangerous product. My son has brought an illness home from school and the entire family is sick. Being too unwell to properly clean and disinfect I sprayed Glen 20 on all door handles, light switches and heavy-traffic, heavily touched surfaces. Within minutes my throat closed over, my chest became tight and I had pain and discomfort… Read more

breathing. My two children complained of swollen glands and even worse sore throats and shortly after nausea. I do not normally use aerosol products and most of our household use is reusable products but through desperation opted for this today. It is a dangerous product. To bring on symptoms like wheezing, swollen throat and chest pain there is something truly wrong. Glen 20 should be removed from the market. Soap and water followed by a wipe down with disinfect (or as I use, vinegar) is the only way to go. Glen 20 today, cancer tomorrow.

I had serious trouble after direct exposure to the product – Four days ago my friend and I were having a play-fight and he was chasing me with a can of Glen20. I ran into the bathroom to hide. He shut the door and sprayed the Glen20 directly into the room for around 3 minutes. I had very bad fatigue, dizzyness and constant wheezing. It has taken four days for me to regain normal breathing free from… Read more

wheezing, but I still have a fairly consistent hacking cough and severe headaches. My breathing still plays up at night, and from physical exertion, but I am now slowly recovering. I'm not friends with this person any more.

A bit iffy – I was using the Berry Breeze Glen 20 and loved the smell it left throughout the house. After reading further reviews I am now concerned regarding the ingredients and how it affects health of myself and pets. Will do some further reading I think.

DO NOT SPRAY THIS PRODUCT – My partner sprayed this yesterday. I was in a different room, but he may as well have sprayed it in my face. It was like bitter poison up my nose & in my mouth. I put the fan on full blast & pointed it at the bedroom door to try to get the smell out of the room. I opened the window as wide as possible & stood there waiting for gusts of fresh air… Read more

to inhale. I couldn't escape the smell. I then sat by the window with a cardigan over my nose & mouth. This is horrendous, toxic stuff & now it's where it should be ... in the bin! I'll make sure to put the garbage out before my partner gets home & if he asks about it, I'll tell him to read these reviews.

Glen 20 > 1.3 butadiene = proven carcinogen. Cause lymph, breast, respiratory cancer in animal studies – Glen 20 > 1.3 butadiene = proven carcinogen. Cause lymph, breast, respiratory cancer in animal studies. does not state this ingredient on the spray can, it's in there Safety Data Sheet though. Should be illegal. Safety data sheet also says that you should were a full respirator when spraying and leave the area. So it's basically full on poison when they make it seem like a causal ethanol disinfectant. Show details

Shocking chemical cocktail – Stinks, affects nose and lungs, leaves a horrible taste, causes headaches. Original Glen20 from years ago didn't do this. If it wasn't broken, why the change? Bring back the proper Glen20 Show details

Health hazard – I have used Glen20 for years but had not used the newer versions on any fabrics until mid-December when I decided to vacuum the mattress and sprayed it with Glen20. I developed bad hay fever symptoms, sore throat, constant coughing, conjunctivitis, sneezing and these symptoms are still present 3 1/2 weeks later. It had not occurred to me until now… Read more

to check Glen20 reviews, I immediately stripped the bed, vacuumed the mattress again and left the bed to air for 24 hours. Last night was the first time I did not wake up coughing, sneezing and having to use throat medication several times. This product is dangerous to humans and should not be used on fabrics. Keep it in the toilet where it belongs.

Complaint Glen 20 and ? how will I get my money back for the unopened containers – Fact - The Gen 20 original scent recently purchased has left a terrible, lingering, and nauseating odour after the spray was used as recommended. I would like the remaining 6 double packs and 2 single cans to be refunded as I am not going to be able to use them. If you want them back please also send the parcel for this quantity with the return… Read more

paid postage as I will not be using them (just makes me feel too ill). I do not have the dockets for these.

Dangerous. Ingredients not listed. Fragrance = TOXICITY – After my workplace adopted heavy-handed use of Glen20, I experienced; sore throat, breathlessness, rasping, migraine, dizziness, nausea, numb & tingling face and heart palpitations . Dangerous, don't use near children/living things. Deadly.

Worst product ever – This product stinks. The stink doesn't go even with doors open for hours. Its given me a horribly sore throat for the last 48hours, feels worse than flu sore throat and hasn't dusapated yet. Makes glands swolen and nose runny. A horrible, terrible product. I'm sure it doesn't even work. I want my money back!  Show details

Kills covid but nearly killed me – I used this product and developed a severe anaphylactic reaction that caused my throat to almost completely close over. I'm not sure if it's the ethanol or the essential oils in the ingredients. This product should come with a clear warning, and never be used near children, pets or people with chemical sensitivities.  Show details

Glen 20 all in one – I am really sorry to say that these Glen 20 products, and covering all the scented ones too, are really Awful .. I have been buying Glen 20 since day one, and the ORIGINAL Glen 20 was by far the very best EVER. Please go back to original Glen 20 I will buy for ever :)  Show details

Glen 20 Pure – I have used Glen 20 for years and always found it great. However the new Pure range is a bit of a disappointment. The scent is OK but the can lacks pressure and the nozzle dispersal is poor, I'll stick with the standard cans..!  Show details

Hard to breathe – Terrible reaction after spraying, goes straight to your lungs, leaves a bad taste in your mouth & throat, causes coughing & breathing difficulties. I don’t recommend it, especially for people with respiratory problems.  Show details

Bring back the old Glen 20, this one stinks – Years ago, Glen 20 used to smell lovely and was a pleasure to use. The Glen 20 for at least the last 10 years is vile and lingers and gets right up your nose and into your lungs!! It's disgusting and should be changed back to the original formula. Won't be buying again. Show details

A truely scary product – Glen 20 doesn't smell too bad. But once sprayed into the air, the taste in the back of your throat is vile, and the breathing difficulties can go on for days. There are much better and safer ways to disinfect. I avoid it as much as I possibly can, but work colleauges use it regarless of my requests for restraint. Their theory is that if I'm not… Read more

in the room at the time of spraying then it is harmless. Wrong! I worry about going into shops etc during the pandemic to find out too late that the area has been doused in poison. But the worst situation to find yourself in is when toilets have been blasted with this garbage. Being caught in a confined space and forced to breath this rubbish is beyond awful. Antihistamines & Ventolin offer little relief and the symptoms last for days. Why is this product, & other similar sprays, still on the market?

Strength – I purchased Glen 20 for the first time after Covid 19 was prevalent. To be fair I did not read instructions. I chose to purchase from family opinions. I am glad that I only purchase 1 for $10. I have too noticed the the strength of the spray as soon as I depressed nozzle. It was so strong I could taste it. I have discarded the can. A message should be clearly visible for those with respiratory conditions. Show details

My opinion of Glen 30 – Only found bleach (problem on some surfaces), methylated spirits (95%) alcohol and Glen 20 that kill viruses. I use Glen 20 because I really want to disinfect items such as packaged loaves of bread, milk bottles etc, going into my fridge. The smell felt really bad, especially the first time I used it. I have had no adverse reactions. I can't… Read more

manage to wipe every product all over, so just liberally spraying saves my sanity. (I am however worried about the chemicals.)

Next time I shall try a blue surgical mask and perhaps disposable gloves because the spray does hurt the skin on my hands.
