How to Remove the Smoke Smell From Plaster

Updated February 21, 2017

Removing the smell of smoke from inside a home or building can seem difficult. One reason why the smoke smell sicks around so long it that the soot and ash particles actually cling to the surface of items in the building. To eliminate the smell of smoke, these particles must be removed from all objects. Cleaning non-porous objects such as plaster is easy because the soot is only on the surface of the plaster.

Pour 1 gallon of water into a bucket and add 1 cup of white vinegar. Stir the solution with a spoon to combine the liquids.

Insert a sponge into the bucket to absorb the liquid and squeeze the sponge to remove most of it.

Wipe down the entire surface of the wall using the sponge. Dip the sponge into the bucket frequently to rinse off any soot or ash and to absorb additional liquid.

Allow the plaster wall to dry completely. As the wall dries, the smell of smoke and vinegar will dissipate. If the smell of smoke persists after one day, wash the plaster again using the same technique.


It is a good idea to wear cleaning gloves while performing this procedure.


Do not use a scrub sponge or an abrasive cloth on the plaster.
