With a bottle can clean a sentence about 3 times, I find that the coverage is also in order.
The cleaner contains an effective indicator of the Colours Purple Reinigungsschaum dark when the medication works. A huge Sauerrei but somehow nice for the child in the man.
The smell of the agent, however as has been written here, too, is anything but good. Although this cleaner should be acid-free, so give the smell still the acid could be included, it smells somehow Mandeln.Ein little perfume would remedy this situation. But since it is used outside, you can see over it.
As for me, the cleaning performance is paramount, to clean my wheels regularly and the cleaner stops here what it promises, I forgive the full 5 points.
