Rim Cleaner with "wow factor" - not for the faint noses

After have this time set in the summer wheels stubborn brake dust and dirt, and with conventional cleaners (Cillit Bang, Sonax wheel cleaner acid-free, div. Polishes, + toothbrush) little chance was to reduce this effectively, I chose this product chosen (acid-free, something effective than other cleaners, test winner).
As noted several times, the product is not for delicate noses (it stinks beastly). Shortly after spraying with selective foam jet, the soiled surfaces darken purple.
After the exposure time of 5-10 minutes with a soft spray then came the wow factor. The dirt can be removed almost entirely of its own accord. The best cleaning effect is achieved, however, with some mechanical help in the form of a toothbrush.
So, spray dry rim, leave, nachbürsten something can continue to act, rinse and finish.
Stubborn places sprinkle a 2nd time and repeat the above process.
The 4 wheels I have inside and outside sprayed up to 2 x generous and the bottle is full too 1/3. The cleaning effect and force bear no relation to previous strenuous cleaning orgies.
The summer wheels have a few years under their belts and now look like new again. From with, there's a strong buy recommendation and despite stink perfect score.
