Until now I had sworn to NIGRIN 74056 Rubber care. Nevertheless, I tried these remedies, because it requires no pressure bottle. Maintain it does very well, even plastic parts (such as: caravan roof) are as good as new again. It can be sprayed either on the lobe or equal to the large area. Even warm surfaces (solar) do not lead straight to disaster streaks. If the rubber surface or plastic surface is very dirty, you can take the remedies of Liquid Moly cope clearly better than that of Nigrin. When Moly is apparently something with it which replaces the dirt better and then evaporates obviously. It does not stink in my opinion though, so it might be sometimes used for emergency inside. Conclusion: as the above-mentioned by Nigrin, also a great tool, but also helps with no real additional effort during use, (older) to remove dirt.
