Yes you can clean walls using Pine Sol.
Just mix a cup or two of pine sol into a bucket of warm water and then use a sponge to clean the walls off.
The pine sol will help clean the walls and also disinfect the walls and get rid of any dirt and grime that may be on the walls.
You can also mix some water and pine sol together in a spray bottle.
Then spray the walls with the pine sol and water mixture and then use a sponge to wipe the walls down.
I use a sponge and some pine sol with water in a bucket and go over my walls every spring to help remove dust and dirt and other grime that can be present on the wall.
The pine sol not only cleans the walls but kills germs on the walls and other surfaces as well.
