Cleaning the front seats, rear seats and entire carpet!

Hello dear friends! I drive a V40, 1.8, petrol, 90 kw, BJ 2003, MJ 2004, Phase II, Motor B4184S2 and automatic gearbox AW/ 50-42. I would like to end July the front and rear seats and the carpet in a specialist workshop for cleaning the cars with us in the city! The problem I have there are the front seats. As we all know, the front seats (driver.- passenger seat) are wired under the seat and connected to the sides and head airbags! In addition, every front seat is fitted with a mechanical sensor. That is also active when the battery is jammed off! If water or other liquid elements come on the front seats, there can be very big problems. That’s my at the moment very staple thought, even if the battery is jammed off. Can I trust the people who clean my car from inside or can’t I? This post is free for discussion! Many nice greetings from the very hot Slovakia from Torsten (Poken)
