Since 1988, we have the plastic sink "Silacron" (in white) of the company Blanco in use and have them maintained so far with the care product "Blanco Clean" (from Fa. Blanco). Thus, the company has stopped production of the Blanco "Blanco Clean" set, we had to look for a new care products. Here we came across the "Collo Polito balm". In our experience the "Collo Polito Pflagebalsam" is many times better than the old care products. The water runs much longer on the surface and it remains thus also significantly longer clean. This is especially to remember it when liquids such as coffee were poured out in the sink, which amounted to the fact that exhibited farblicher veil on the surface after a short time. We were very pleasantly surprised by this product and can recommend this balm with a clear conscience!
