It doesn't clean even when used undiluted! Let alone when diluted!! It only cleans hands from dirt. So, useless!

The best at the ideal price. It works almost miracles in some cases. I am absolutely satisfied overall with the company's products. Proof is that I now buy them in large packages…

It does what it promises, I used it on a Ford Focus mk1 engine that had never been cleaned before, without scrubbing I rinsed with a sprayer, and I couldn't believe what I was seeing, in the end the engine looked brand new. Incredible.

Amazing cleaner, it has become my permanent friend for cleaning enduro motorcycles, cars, and anything else you want. It does not cause damage to materials

Very good product. I use it with a MaxShine brush and it does an excellent job on metals. On plastics, it leaves a residue (like all degreasers) but it cleans up easily. I have cleaned the engine bay, the underside of the hood, the exhausts, parts of the suspension, my tools, etc.

It really works!
In a vehicle that hadn't been cleaned for years, with three sprays, without any dilution and rinsing with water in a sprayer, the result is this...

It needs dilution with water as indicated on the label, the ratios depend on the dirt that needs to be tackled, 1:5 for heavy dirt up to 1:20 for simpler use and maintenance of the engine and other parts of the vehicle. I haven't noticed any fading on plastic parts or hoses. It can also be used for washing the rims without leaving dirt on the tire profile that it drips through.

Basically, I bought it for cleaning engine sumps. Since I am involved in restoring, I am interested in cleaning engines from old-burnt oils. What I found is that it cannot remove the "tough" stuff from the surfaces of the sumps. It reaches only as far as the gasoline I was using would clean! The positive thing is that it does not have the harmful effects of the toxicity of gasoline in terms of fumes and flammability.

Excellent cleaner for oils, powders, salts, and many more! You can dilute it for lighter dirt. This is the first product from K2 that I have purchased, and I am amazed.

Excellent for the money it costs. It cleans the engine bay that I tried very well, and leaves a very nice light shine. It is very powerful without any scrubbing, and in some areas where scrubbing was needed, it works wonders.

I don't need to say anything, just look at the photos.

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.

Excellent cleaner. Easy to use. I have cleaned car engines and motorcycles. It easily removes dirt and residues from the area you spray it on.
