I've used to protect my kitchen top, a german product, Lithofin
Stainstop (what a smell!!! really nasty)but he has left a film on top.
How can I remove it?? I phoned in the main office in Germany and they
don't have a clue... they told me that I had 20 minutes to remove it,
after that it's impossible to remove it...

thanxs for your help
