The five hundred milliliter Dose (0,5ltr) is equipped with a special spray head. By "Präzisionssptühkopf" technique called the agent is to be sprayed on the dirty places more targeted. Although this is already old hat, but it works. Evotec intends to solve even stubborn brake dust. This works quite neatly with car wheels. In other stubborn stains such as by chain oil / grease contaminated motorcycle rims the Nigrin doing but also difficult, in spite of standards met manufacturer's recommendations on how to proceed. But wonder I had not really expected. Since the turning color "action indicator" nothing helps. Kettenfett remains handwork. However, even the rim and then the Nigrin perspective promise.
The price is okay and I can recommend the EvoTec for the Bundesliga afternoon as a cleaner in good conscience. Smooth surfaces regularly maintained cleans the EvoTec reliable. For gimbal, or strapless bikers Nigrin is but one of many. Also Nigrin cooks up only with Evotec.
