If you're looking to get stains off walls without removing paint, there are a few things you can try. First, you can try scrubbing the stain with a damp cloth or a sponge. If that doesn't work, you can try using a mild detergent or soap. If the stain is still there, you can try using a stronger cleaner, like bleach or ammonia. Be sure to test a small area first to make sure the cleaner doesn't damage the paint.
