We have received many questions from our customers about our 'magical' water and machines. 

To ensure you find the answers you need as quickly as possible, here is a compiled list of commonly asked questions broken down into the 6 fundamental categories.



1) Who uses Clenzd? A: Anyone in need of sterilization basically. From the yummy mummy cleaning her toddler's toys, to the kiasu aunty next door mopping the floor after coming home from the market, to your favourite sushi chef cleaning up after preparing your favourite sashimi, to that dreaded dentist sterilizing his apparatus after scaling your teeth. 2) Who benefits from using Clenzd? A: You, me, your boss, my boss, your BFF, my BFF, your cat, my dog, your son, my daughter.... and unfortunately, even your mother in law.


1) What is Clenzd? A: Everyone we explain to says it's “magic” water. Yes it does sound too good to be true, but it really is. Clenzd is a slightly acidic (pH 5.0 to 6.5) sanitizing water (HOCl) that has been tested and proven to eliminate 99.999% of viruses, bacteria, fungi and yeast. It is non-toxic, child safe and environmentally friendly. It is colourless and has almost no taste or odour. More explained here 2) What is the Active Ingrediant (AI) of Clenzd? A: The AI in Clenzd is a slightly acidic hypochlorous acid (HOCl) 3) What is HOCl? A: Hypochlorous Acid (HOCl) is nature’s own germ killer. It is a weak acid your body's white blood cells (Neutrophils) produce to kill bacteria, viruses and that invade your body. It leaves no residue and has little odour. More information on HOCl 4) What is HOCLER A: HOCLER is a market leading patented machine from South Korea that is used to produce Clenzd. It uses a patented method to electrolyze tap water with food grade 6% Hydrochloric Acid. Don't worry, the Hydrochloric Acid is food grade and commonly used in food packaging. The HOCLER machines electrolyzes tap water and HCl in a barrierless electrolytic bath to produced HOCl water instantly. 5) What can I mix Clenzd with? A: Just like a 1946 bottle of Macallen, Clenzd must be used on its own. It should NOT be diluted. It should NOT be mixed with detergent or other cleaning or sanitizing agents as it will change the chemical properties of Clenzd. 6) What happens if I use Clenzd past the expiry date? A: The Active Ingredient in Clenzd slowly breaks down over time. Based on Singapore's weather, it will stay effective for at least 1 year from bottling. Using Clenzd past its expiry is not harmful either. The sanitizing properties may be reduced, ie. it will take longer to sanitize the surface. So instead of sanitizing in 30 seconds, it may take 1 or 2 minutes to achieve the same sterilizing results. 7) What happens if I accidentally drink Clenzd? A: Drinking small amounts of Clenzd will not result in any severe consequences as the Free Chlorine levels are low at 20-40ppm. Similar to accidentally drinking a gulp of swimming pool water, nothing will happen. We definitely do not recommend you to water parade using Clenzd. But if by some 'Final Destination' chance that you drink an entire bottle of Clenzd, please see a doctor immediately.


1) Where is Clenzd made? A: Clenzd is proudly Singaporean, its produced locally but thankfully doesn't need to do National Service. It has found its way into Army Camps though… 2) Where shall I store my bottle of Clenzd? A: In a cool dry place, away from direct sunlight. If you are rebottling into a smaller bottle, do ensure that the bottle is opaque. I wonder if Clenzd is afraid of garlic and crosses… 3) Where can I purchase Clenzd? A: Clenzd is available through our website or several online platforms such as Shopee, Lazada and Carousell. You may find the links on our product page. 4) Where is Clenzd currently used? A: Clenzd has been around the block. It’s been supplied to many individuals and businesses, namely, preschools, exhibitions, hairdressing salons, pet shops, offices, kitchens, cafes, hotels, showrooms and etc... 5) Where is the Alcohol? A: Clenzd is Alcohol free! If Clenzd could drive, it will be the designated driver for your next clubbing night out! Clenzd is the sober one that DOES NOT require any alcohol to get rid of all the baddies, such as COVID-19, H1N1, Swine Flu, Novovirus, HFMD, Samonella, Legionella, E-Coli, Candida, Aspergillus to name a few... As tested and proven, Clenzd eliminates 99.999% of them in seconds. 80 to 100 x more effective than Alcohol or household bleach.


1) When will Clenzd expire? A: As the Active Ingredient is biodegradable, it breaks down quickly in sunlight and open air. Unopened and stored properly in a cool dry place, Clenzd will stay effective for at least 1 year. Once opened, we recommend you finish using within 3 months.


1) Why does Clenzd expire so quickly? A: As the Active Ingredient is biodegradable, it breaks down in sunlight and open air. Left out in the open, the molecules slowly break down and become innate. 2) Why Is Clenzd safe for children and pets? A: The Active Ingredient in Clenzd is carefully balanced to achieve maximum potency yet kept safe. It has been researched and proven that the balance of pH level 5.0 to 6.5, together with the low Free Chlorine levels of 20-40ppm, achieves maximum sterilization properties, yet produce low Chlorine gas. Clenzd has been tested by Japanese, Korean and American agencies and has been classified as a food-grade cleanser. It is safe for consumption however it is not recommended for drinking. See the safety test reports 3) Why isn’t HOCl more commonly used? There are 2 reasons, one being the cost to manufacture. HOCl was very costly to produce and was only stable for only a very short time. New technology over the years have now allowed for HOCl to remain stable for years and less costly to produce.


1) How do i use Clenzd? A: Clenzd will work on any general surface. Spray Clenzd generously onto any surface, leave it to work its magic for a few seconds before wiping dry with a clean dry cloth. For best results, leave Clenzd to air dry. Do not dilute or mix with other chemicals as it may change the molecular structure of the Active Ingredient. 2) How should I store Clenzd? A: All bottles should be kept in a cool dry place, out of direct sunlight as the Active Ingredient starts to break down in temperatures over 60°c and direct sunlight. Ensure the bottles are tightly capped as well.
