Hello dear motor talk community, I have a concern. I cleaned the window panes of our 2nd car (Opel Tigra Twintop ) today at noon mainly my girlfriend used. I noticed then that white spores are at the back of the passenger seat. When I pushed the seat forward then the shock was great. When I then removed the floor mat and scanned, I found that the interior floor of the passenger side and only the wet was. When I was finished, I looked again in the trunk and got the next shock. Same game, remove everything, suck out and brush off. (-} see pictures ) The assumption is that a water bottle expired on the passenger floor a long time ago. I checked all seals and procedures. Seems to be super. I’m just about to dry the car again. Now my question: What can I noc do? h do it to kill the spores ? Purely optical is almost nothing to see and from smell is also nothing eye-catching ? About feedback I would be happy Dear Greetings Daniel
