How to fix knotty pine spots faded from pictures on the walls

You probably just want to clean all the walls. Rather than fade, it’s likely just years of stuff. Folks clean their floors, but don’t think of their walls.

Cleaning is pretty simple. Maybe get yourself a new sponge mop. I’d wipe down with a wide microfiber mop first, for dust. It’s harder to clean up mud.

Congratulations on your new house. Make it a home.

See if you can match the stain and retain those spots

I would try washing the walls with Murphy's Oils Soap and see if it revives it all. https://www.walmart.com/ip/Murphy-s-Oil-Soap-Wood-Cleaner-Original-32-fl-oz/13281643? If it doesn't then I'd guess you have to try something more drastic like staining it all.

Hello Marsha,

Covering the spots is the easiest way.

We have a 1973 cabin and had both the walls and ceilings professionally sanded and re polyurethaned. It was a massive and dusty job, we started to do it ourselves then surrendered to professionals that knocked it out in 4-5 days.

This incredible makeover made the cedar walls and ceiling look like new- to eliminate all the stains, fading and defects acquired over the dcades. In our own particular situation the ceilings were the in the worst condition with black water staining and spottiness.

Try a stain. Wash the wall and get the closest color. Take a rag and dip a tiny bit in the stain and start on the faded area and work outward. You can build color by adding another coat but you can't remove it once it is on and you have to sand and start over. A little stain goes a long way.
