Warning! ALDI Anti slip mat

Hi, unfortunately I had to find out this morning that the Anti-Slip Matte (Aldi) had not grown to the temperatures and the sun at the weekend. A part of the matte has melted and the liquid silicone on the amature board run down. Of course, the whole thing is an extremely sticky and disgusting matter. So a warning to all those who have this or similar products in the vehicle, the summer is just beginning! Does anyone have any idea with which means I might have a chance to remove the sticky stuff?
