Interior Cleaner

Want to give a width to cleaning the interior walls are usually dirty. Is there a soap I can use on large surfaces? I prefer not to use a lot of spray cleaner.

Yep wash the bottom up is important. :)
And any type of all-purpose cleaner (Pine-Sol, Mr. Clean, **** and Span) solution, would be an excellent job.

Well, my favorite is housekeeper lemon scented ammonia. I dilute it in a spray bottle (quart size consumes about 1/4- 1 / 2 c. ammonia, fill the rest of the waterway). It removes grease and oil (fingerprints, etc.) very well. It is inexpensive. It leaves no haze or film. No rinsing required. You can also clean the vinyl siding with her. Mix a sink full, use a mop ...
It is so versatile and cheap! My mother used, too, 20 + years later.
It's great on the wallpaper too our bathrooms are all carpeted, and that's all I've ever used.

Mr. Clean diluted in water. For stubborn stains use all his strength, but do not rub too hard or it will remove paint.

First make sure the wallpaper is washable. Try somewhere a little patch of road. In this case, you can use most any type of all-purpose cleaner that you put in the water. The day old **** & Span works quite well. When you wash the walls, always start from the bottom and work up. If you start at the top and the water flows over the drywall, you'll get streaks that does not come off.
