white lime stains on notty pine walls

Post Reply | Watch this Post

I have the most beautiful bedroom. All of the walls and ceiling are notty pine and is close to 100 years old. Recently I had to use a vaporizer in my room and because I have always closed my bedroom door I didn't think anything of until a few days later I noticed a lot of white stains on the upper walls. I have cleaned them with warm soapy water, vinagar, lemon jucie and now Lime Away. The lime away toned the white down but the stain is still there. Help any one have any ideas. I have run out.
