Initially even I was skeptical as to whether this means actually delivers what it promises. True to the motto: "Learning by doing" I've tried the remedy itself. Conclusion: After cleaning of 4 bikes with different "Grunge states" I am completely convinced. Spraying (without pre-cleaning), leave on short and cumshot by water-hose, then rinse DONE! Grabbed even years Kettenfettschmodder deposited in the sprockets. Highly Recommended. Bought in 5 liter cans, the price is also bearable. The 500ml bottle is enough for about 4 bike washes.
