3 Weeks ago we did a massive blitz on an asthmatics house whilst they are away. The whole house was done, walls were wiped down and curtains washed or vacuumed.
I've had the windows open every day, I've been vacuuming every week but there is still a lot of dust coming up.
I think the dust is in the air and is settling down, it still feels dusty inside. I also think some is embedded deep in the carpet and slowly coming up.
I'm amazed by how much is still being collected. How long do you think it will take to become clean?
