Sugar soap is a chemical cleaner composed of sodium carbonate, sodium phosphate, and sometimes sodium silicate. Sugar soap is commonly used on walls as a priming solution prior to painting. Sugar soap can also be used to clean walls, floors and cupboards. When using for cleaning purposes, the sugar soap should be diluted. When working with sugar soap, precautions must be taken, since it is a chemical cleaner. Eye goggles, rubber gloves and a protective face mask should be worn.
Add 1 tbsp sugar soap to 590 ml (2 1/2 cups) of warm water in a bucket for normal cleaning. For deep cleaning or greasy walls, dilute 1 tbsp sugar soap for every 235 ml (cup) of warm water you use. Stir to dissolve the sugar soap.
Dip a sponge, cleaning brush or cloth in the mixture. Rub the mixture onto the walls. Start at the top of the walls and work your way downward. Continue until the wall is clean.
Fill a spray bottle with cool water. Spray a small area of the wall with the water. Use a towel or rag to dab up the moisture. This will remove any remaining sugar soap residue. Continue in small sections across the wall.
Allow the walls to air dry.
Sugar soap should never be used on wallpapered walls.
