It is very pleasing that the process is carried free of acid. There are also cleaner (there are wheels of hell) the acids and the paint attacks on the Alus -> Yes, "90%" of the aluminum wheels are painted ...
The paint as you get there do not pay attention is dull and over. That can not happen so quickly here.
At the same time one has the risk that the cleaning performance is not good. I could not find here.
There are many videos where people spray their dirty rims and then they shine again. Honestly Totaler waste. Most would have managed it with a normal water jet!
To me it is important that the brake dust go away. I have tried the on the rim of my dad because he had washed it for 2 years from the outside but not the inside ... brake dust burned at its finest! I did not get down the. The silver rims were inside after washing still black "dots". Then ordered the cleaner, well-sprayed and waited until he turned red. Then with a brush starting the Gelump to get down. Result: 90% the first time way. I forgive the acid-free cleaner also.
Then the whole a second time and now the scattered remains have also disappeared.
Even if I had to play a second time, the contamination was extreme and that would perhaps hammer out only with an acid-based wheel cleaner and a passage, but I want the paint afterwards is still on it, and take up the then gladly accept.
That's why from me 5 stars!
I hope this helps some more ...
