The K2 engine cleaning liquid immediately cleans areas with oil and dirt and leaves the engine compartment much more tidy without much effort.

The K2 AKRA engine cleaning liquid did an excellent job, it immediately cleans areas with oil and dirt and leaves the engine compartment much more tidy, without requiring much effort.

I sprayed locally and with a brush I cleaned the dirty spots, continued with water without pressure and all the dirt was cleaned

Good but I wasn't thrilled! I first cleaned with Koch Chemie GS at a 1/5 ratio for tough dirt. I used this but I think the previous one did a better job. It's not bad though and I might use it again.

It's the first one I use due to reviews, first time cleaning the car engine (it wasn't very dirty in general) and I see that it made a difference compared to before. At first, I cleaned with a little water, wiped it, and then sprayed with the product and cleaned it with a microfiber cloth. I couldn't clean very low, but as far as the brush could reach, nevertheless I liked the result.

Easy job with a very good result. You spray, scrub with a brush, and wipe with a microfiber cloth. No rinsing with water. However, be careful, spray where you will clean, not everywhere, because it evaporates relatively quickly.

Amazing product, does exactly what it promises with great success and ease of use

Bought it as a joke, not expecting it to do much, but to my surprise, it managed to remove 30+ years of BMW wax from the engine and air intake with relative ease! For that reason alone, I never go without it anymore

It does what it promises, value for money purchase! I would definitely buy it again and it's perfect for cleaning the engine and plastic parts. Purchase through Scrooge very quickly and delivery to the box!

very good, it does what it says. the secret is to let it sit for a bit and then with a cloth that you won't need again, you collect it. also in areas where your hand doesn't fit, you can use a small brush

I can say that it cleans the plastic parts of the engine well, but not the aluminum and iron parts that have retained most of the dirt. Of course, with a little scrubbing it comes off, but nothing amazing. It will be tested until the bottle is finished and we'll see.

It doesn't remove oil and deposits from the engine even if you pour the whole bottle... only if you put the pressure washer very close. And we're talking about very light deposits, not anything crazy. It's for very light cleaning

I don't have much experience with these, but it did its job just fine the one time I needed it. Very good especially for its price

Personally, I got it for cleaning the removable parts of the chainsaw. Good result in terms of removing accumulated sawdust and chain oil. I rinse the removable parts slightly with water. A similar product from Wurth that I have tried for the same use had better results, but it finished very quickly while it was almost double the price. So, due to performance/cost, 5 stars from me.

I cleaned the mud that had accumulated on the car doors that had never been cleaned at the points where the hinges are.....it did the job alongside a brush to avoid scratching the paint because the mud had become a mountain. Also, for those who say they didn't use it because it needs water for rinsing.....personally, I didn't take a hose with water to rinse it but a spray applicator or vaporizer....it doesn't need a pressure washer to be rinsed

Unfortunately, I did not use it because the instructions state that afterwards it definitely needs to be washed with water, and in fact with pressure and thoroughly, because it damages the engine, so it is not suitable for engines. And those who know, washing the engine is disastrous, especially if you do not take very strict precautions. However, I used it on the aluminum rims which were quite dirty, it did the job but not 100% even though I left it on for much longer, with just rinsing it removed most of the dirt and then it needed scrubbing with soapy water and a sponge to clean satisfactorily.

I poured water on the engine of the car (yaris1999), sprayed quite a bit of the cleaner, rubbed a little here and there with the product on top.. and the result was dazzling..

I have an Audi A4 B8 and I use it to clean the engine. First, I spray the liquid everywhere carefully, making sure it doesn't go into the intake, then I clean with a special brush and finally, I spray with water without pressure.

As most have said, the product does its job perfectly! Not that I was very dirty since I clean regularly, but hard-to-reach spots, along with the help of K2's round brush, gave the result you see!

I don't need to say anything, just look at the photos.
OCV (Oil Control Valve) from a Toyota engine.
It works perfectly this way, the spray does a good job but not as good as leaving the item submerged in K2 Akra for 5-10 minutes.
Also do a chemical wash (with another special material) to eat away the rust and the replacement will be practically like new!

Hard dirt from years of oil leaks in the diesel engine changes their lights. Without scrubbing, just spray, wait, and rinse with water. If you repeat it after a while, it makes it new again.

Stains from oils and grease are cleaned immediately. For the "tougher" stains, a little help from a brush or toothbrush may be needed and it makes them look new! Buy it with closed eyes!

With one bottle, you do the motor 4-5 times.
Some areas may require scrubbing with a brush.
A lot of dirt comes out.
Then rinse with water using a sprayer.
I can't say it does the perfect job, but it's worth its money and more.
I would buy it again

It does a great job, especially if you use a brush to scrub the surface, the result will justify you. It also works for wheels, where it collects dirt from the brakes, mud, etc

It does exactly what it describes. Honest for its value. After cleaning the engine, I sprayed it with silicone spray, generally using Motip, and besides how clean it remains, no dust settles on it at all.

Excellent! Especially for its price. I cleaned my car engine with this product, which had oil and dirt buildup from the previous owner for 14 years. It removed everything from the engine and the metal parts. Since my car is white, the difference was very noticeable. The only area that it didn't clean perfectly was the inside of the hood, where I assume the dirt is deeply embedded in the paint pores due to expansion and contraction. It needs a polish in that area.

As for the usage, I sprayed it on the engine when it was cold and scrubbed with the corresponding brush from the company. I rinsed gently with water and voila!

I won't buy it again in the immediate future because I want to try an APC from another company, which allows dilution for internal engine cleaning, etc. If you want something simple, very affordable, and don't require dilution and extra effort, then get this product as it is!

Awesome product does what it promises! It cleans dirt like dust and dried oils that have been in the engine for years. It does not damage labels, stickers, plastics, etc.

Very good and economical! It did the job on a motor that hadn't been washed for 5 years. I will definitely buy it again!

For the money it costs, it is quite good. On new cars it is definitely very good, but for a 20-year-old car like mine that has never been washed like this before, on its own it doesn't do much; it needs some work and scrubbing with a little brush to dissolve the dirt. You definitely need a pressure washer for so much dirt; on cleaner cars, even with a garden hose, all the dirt on the engine runs off. It also does a good job on rims.

For 3-3.5 euros, it is definitely worth it and more. After reading the comments, I bought two bottles. My mistake was that I should have bought 10 bottles because it works wonders! You spray it, rub it with a brush, and wipe it off with a microfiber cloth! I also used a silicone spray for the tires and plastics. You can see the result
