Very good cleaner. Alkaline and dissolves dirt in the rails of air conditioners. Smells nice

Very good product. Use according to the instructions. I used it almost undiluted and it got on my eyeglasses and caused damage to the lenses.

Cleaning two air conditioners at the holiday home, dilution 1:5 since it was the first cleaning. I unplugged the air conditioners, rinsed the filters with the liquid and plenty of water, and left them aside to dry. For the indoor units, first a pass with a brush to remove the dust and prevent it from turning into mud with the liquid, spraying with a pressure sprayer, waiting 15 minutes, rinsing with plenty of water again with the pressure sprayer, and waiting an additional 20 minutes to dry. Reinstalling the filters and plugging them back in, cooling operation for 30 minutes, and they became like new! Definitely use a mask, goggles, and gloves because the solution is alkaline; the little elephant is also useful so you don’t dirty the walls.
P.S.: Waiting times and dilution ratio from the ChatGPT subscription.

It cleans very well, it is strong.
4 stars because it leaves a smell in the house for many hours; it needs to be well ventilated

I used the liquid at a ratio of one to four, and the drops that ran down the wall stained the walls.
However, the odors disappeared from the air conditioner

I have used it 5 times in total. It struggles a bit with the outdoor unit. You have to let it run for a while, about 20 minutes. It generally cleans the indoor unit well, but even though everything was cleaned, after a week that smell came back again.. I don't know guys, I did everything right, I cleaned it very thoroughly and rinsed it very well, but the smell came back..

excellent, it cleans very well and smells nice. I used it with professional tools, sprayers, brushes, plenty of water to rinse it off.

Very good! Just don't let it drip on the floor, it needs vinegar and scrubbing.... if anyone knows another way, please let me know

Very good, professional product. If you combine it with a little elephant, you can clean the ACs yourself and have peace of mind.

Excellent product! It came highly recommended by a professional A/C cleaning technician. He recommended to use it on the internal and external part of the A/C unit. If you are going to do it yourself, just remember to use a ratio of 1 red "kapaki" of the AIR-CB-3 cleaner to 5 liters of water. Then, fill up your gardening water sprayer and clean the internal and external units. Although he recommended to just leave it and leave the A/C running for one hour and let it dry, in the pamphlet (by the Eurochem company) it says to rinse off the chemical with water after 10 minutes. You decide. : ) I did it myself and will be saving a lot of money over time. It's a great investment!

Very good product

Probably the best cleaner for indoor units. You can feel the freshness of the air from the very first hour after application

Cleaning was done on three air conditioners. It seems to do the job, but the air conditioner that works the most started to smell again relatively quickly, so it needs cleaning again. Of course, we are talking about a ten square meter room where people are constantly coming and going

Second time I buy it, simply the best, however it has quite a strong smell while you use it, obviously not after cleaning, it doesn't smell at all, especially if you rinse as an extra step (I do that)

Perfect product and according to the opinion of the air conditioning technician, it does not need rinsing with water but activation of the a/c for at least 20 minutes at the lowest temperature. For the outdoor units, I left it for 20 minutes and then rinsed them with the hose. Even though the technician who came last year only sprayed the chemical and said no water was needed. In 5 minutes he (cleaned both) charged me 40 euros and left. So I looked into doing it myself and I was very satisfied.

Very good liquid, the air conditioners were cleaned very well, it doesn't smell too strong and has a subtle lemon scent when you turn on the air conditioner after cleaning.
Overall, very value for money as with the proportions you use, it lasts for several cleanings.

It did a very good job on an AC where the removable filters were cleaned regularly but it hadn’t had a full cleaning in three and a half years. With a dilution of 1 to 3, that is 0.5L product to 1.5L water, I sprayed the AC element and the fan with a pump sprayer. I left it for a while. I used a small brush on the fan and then rinsed with a hose with a nozzle at the end, carefully so as not to flood everything. Excellent result and the odors were eliminated when the AC was running.

strong chemical, it cleans but requires thoroughness.. Mask and good rinsing with water!!

Anyone who has worked with professional cleaning products from NCH knows that this is good only as a floor cleaner and nothing else

Perfect product, it does what it promises, cleaned everything. Most plumbers use this. The ratio of liquid to water is 1 to 3.

Used for cleaning the home air conditioner, it really did its job well both on the coils and the fan, and in the end, it leaves a nice fresh scent. Value for money

Perfect product and according to the opinion of the technician, it does not need rinsing with water but activation of the a/c for at least 20 minutes at the lowest temperature.

Very good for indoor unit only, but be careful it is still a chemical. For the outdoor unit, it needs something stronger because there are stronger salts and dirt. I highly recommend it for the indoor unit.

I washed the internal and external units and removed a lot of dirt with a dilution of 1:5. It does its job very well and in combination with the Karcher OC3 pressure washer, it makes the air conditioner and the fan look like new.

Nice product, it seems to do a good job. I diluted it with water 1/3 in a pump sprayer. Don't forget, plastic gloves, a mask on the face, and a thorough rinse at the end with plenty of water.

I didn't see such amazing results. I initially diluted it 1:3 and then 1:2. My machine had moderate dirt, mainly on the fan. It cleaned a bit and definitely removed odors, but it doesn't work miracles. If you don't clean the entire machine and use a pressure washer, don't expect it to clean thoroughly. It needs to be done every 6-9 months with this material from the first time you bought the air conditioner. If it gets "dirty" after 1.5 years, it doesn't clean differently.

It does not leave any fresh scent after use, but the bad odor it had before the air conditioner completely disappeared. Easy to use and economical. I recommend it

First time I used it and I must say that it really does an excellent job. I'm not a professional, but out of all the products I have tried, this one did the best cleaning. I also used it for the exterior parts which, after rinsing, shined like new!
The only thing left now is to find a good pressure sprayer, because the one I got (although not the cheap ones) couldn't handle the pressure and created cracks in the inner plastic tube.

For a simple a/c cleaning, it does its job. It smells a little for the first 1-2 days after application, as it is an alcohol-based solution, but I prefer it because I use it in a sprayer diluted with water, in a ratio of 1 to 8 or 1 to 10, so it lasts for several applications.

Very good.
