I recently bought the flash dash product from car plan (image below). You wipe it on your dash and it's meant clean it. Well it's ruined my dash completely. Nowhere on it does it say it will stain the dash. But that's what it's done. I'm really upset as my car is brand new and cos alot on money. I emailed them and all they said is sorry try window cleaner to get it off. I've tried this with no luck. I'm warning you all about the product.
I will be taking the case further and hopefully to court for them to fix my dash.
