I have the canister rim cleaner bought because it is significantly cheaper than a single spray. The cleaning result is very good, no question. The slightly thick consistency the cleaner adheres well to vertical surfaces. The dirt from the winter has been removed without difficulty without major mechanical reworking. Is very uncomfortable but the extreme stench of the agent. Who has ever put his nose deep into a cesspit, get a good impression of the smell. I live in the country with several farmers in the neighborhood and am so some unpleasant scents usual but this one really tops everything. And that is no exaggeration! Who therefore has no problems is well served here. (Ie = UTF8 & qid = 1429468170 & sr = 1-17 & keywords = + SONAX Rim Cleaner) odor-sensitive for all the "Nigrin Turbo Rim Cleaner" is more appropriate. The smells much more pleasant and is the evotech in effect in every way.
