Have ordered together with the chain cleaner Caramba my spray. Once I had all the encrustations removed with the cleaner and a steam cleaner, I have the chain, derailleur pulleys and sprayed with the chain spray, can move short and away too much oil brushed with a cotton cloth. The bike handles like buy new and the circuit responds (again) extremely precise now. I especially appreciate that the spray is transparent and the chain thus not so fast dirty pants should it times come to the sprocket. Visually, it is of course also a cleaner impression.
Strong buy recommendation from me for the said purpose!
