Positives:
+ Short exposure
+ Very good cleaning performance, even on the narrow points (for which the cleaner actually worth)
Easy to handle + in the spray bottle (Einsprüh-Einwirk Dishwashing dryness)
Negatives:
- (Better order 1 liter bottle very expensive the 25 liter canister => only costs about 3.80 EUR (!!!!) per liter.
Conclusion:
Muc-Off is recommended as a good cleaner. Nevertheless, one can not avoid a subsequent cleaning if the bike should be squeaky clean (dry cleaning). The rear derailleur should be treated separately degreaser after preliminary cleansing and be lubricated non-greasy (eg similar dynamic with dry lubricant).
All in all it can be said, however, that you can bike no less than clean with the simplest dish soap. It is thus at least as clean. Do not be afraid of excessive water use, it finally is outdoor sports equipment !!. It is only important to have the wheel completely dry. Then costs only a hundredth of the price.
