I don't know why, but our walls get dusty so fast. I've been trying to use the vacuum, but the hose isn't long enough and the brush attachment is too small.
I gave up and bought this for my wife
These might be the ticket:
Use swifter dry mop to dust them off. If you use wet then dust turns to dirt then you have to wash. Hope it helps
I use a few things. Bleach, simple green which works on anything even putting it in ur laundry. That's what has been best for my walls. Hope that helps u. =)
Dryer sheets work well for dusting. It also helps prevent dust as well and leaves the house smelling nice. Might be worth a try but I would probably just buy a generic brand for that purpose.
