If you have knotty pine walls, there are a few things you can do to clean them. Knotty pine is a hardwood, but it has a lot of knots in it. These knots can get dirty and start to build up dirt and dust over time. Here are four ways to clean knotty pine walls:

  1. Use a vacuum cleaner with a brush attachment.
  2. Use a bucket and water mixture to wet the wall and then use a scrub brush to scrub the surface.
  3. Use an enzyme cleaner like Pine-Sol or Nature’s Miracle on a damp cloth to clean the surface.
  4. Use an all-purpose cleaner like 409 on a damp cloth to clean the surface. ..
