How to clean plaster walls
If you have plaster
walls, you may think that the walls get dirty far more quickly
than any other type of wall inside of a house. Well, you'd
probably be right! That is because plaster absorbs moisture,
and with it, brings dust and anything else that floats around
in the air to stick to the walls.
First, scrub the
wall with a brush (it will need to be soft-bristled if there
is a texture pattern to the plaster wall) to remove any loose
dirt, dust, etc. Then rub it gently with a damp cloth.
Next, clean the
walls with a solution of TSP (also known as Tri-Sodium Phosphate).
You will need a strong solution, about 1:15 ratio of TSP:
Warm Water. Scrub the wall with a brush or sponge, then let
sit for several hours to dry. Then using a mild solution of
TSP (1:25), scrub the wall again and allow to dry. You may
want to use a heater or fan to speed the drying process, especially
if the temperature is colder.
Enjoy your nice
clean plaster walls!
