marc2 years ago000Is it possible to use a product other than the one supplied by Karcher? I have a soap for oiled floors. And is it possible to return the FC7 if after the first use it does not suit me?Show in original language (French)italiaswiss2 years ago000I don't see the problem as long as it's soap, but don't put too much on at the beginning, do a test first. Good day to youShow in original language (French)Comment
