After I had looked at many YouTube videos about the products of Muc Off, I wanted to convince myself of their merits. And what should I say? It works. I have applied the Bike Clean Spray and spray the bike for the aftertreatment. After I moistened my bike only with water, I have the bike Clean tracked and leave for about 5 minutes. One has to say that the degree of contamination was rather normal (ie normal use). After you clean the dissolved dirt with a damp cloth. Works just fine. I then let it dry the bike and subsequently treated with the Bike Spray. It can be applied as the super cleaner. Then allowed to dry again and this wipes possible residues with a cloth away. What remains is a great result with a super shine. Orders Test and convince ;-)
