Whenever the weather is beautiful again, and we use the garden tables after some rain, or even if have settled too much pollen, the cleaner is used. As described I turn him from us, and the dirt will disappear instantly. However, our chairs made of dark plastic and the effect are evident in my eyes rather in bright products. With us you can see the gray haze not really, since the chairs are quite faded. That's why I used the product at our Kunsstoff window frames and at our door on a whim. Here one can see the difference just with detergent / window cleaners cleaned or just with the plastics cleaner Caramba. It is faster and looks into my eyes out clean.
Our conclusion The thumb goes up. Caramba has convinced us. In dark plastic I have to say that I can recommend to you also normal cleaners here. In white plastic Caramba is but a very good solution.
