I made my own surface cleaner this week. Got it from the book Thrifty Ways for Modern Days by Martin Lewis.
It consisted of 1 cup of white vinegar and 1 cup of water put in an old spray bottle. I added a few drops of pine essential oil, only because I had some knocking about. So far, it does the job every bit as well as any surface cleaner I have ever used. Stubborn patches are coming off as easy as anything. I think I will experiment with other possible alternatives. A few months ago I tried to make my own washing up liquid. This was something that I failed totally at. None of what I made ever cleaned anything properly (by that I mean nothing greasy or very dirty.) No use at all, although if anyone has any good ideas I would be more than willing to try again.
