How to Clean Grime from Emulsion Surfaces
You need only a very weak detergent solution for cleaning emulsion surfaces – 60 millilitres (ml) (4 tablespoons) of soap in about 5 litres (a gallon) of hot water. Any multi-purpose liquid cleaner is fine. You can buy cleaners sold either as liquids or as highly concentrated liquids (follow the dilution directions on these). Choosing one with a mild fragrance can make the task more pleasant.
With this mild mixture, hand irritation shouldn’t be an issue, so you may want to wear cotton gardening gloves to absorb extra water rather than hot and heavy rubber gloves. Sugar soap washes walls well too but is much more expensive than the detergent you use for occasional cleaning.
Save the sugar soap for special occasions such as when you’re about to repaint and want to remove all trace of detergent residue.
A sponge mop works best for washing ceilings. For stubborn spots, you can tie a towel over the mop to get added rubbing power. When washing down walls, you can get closer using a sponge (an old natural sponge that’s too tatty for the bathroom works well).
Whether you’re using a mop or sponge, keeping it well wrung will help prevent streaks.
Give yourself a clear area for working, thus avoiding tripping over whilst working. Move electrical items well out of the way, or anything else that may be upset by dripping water.
The first step in cleaning is dusting to remove the light surface dirt. Using brushed lambs-wool is perfect.
