- Removing condensation stains from wooden window frames

 


We have interior wood window frames that have been left unfinished. Condensation from the windows has stained the wood. We now want to finish the frames. Is there some way we can remove the stains in order to finish the wood and keep the light colour?

Tips:

1. Wood window frames and sash that are going to be left for a clear finish should always have a clear sealer applied immediately after installation to eliminate potential water staining.

2. Homes constructed in the cold months of the year will invariably have a high moisture content inside because of drywall or plaster curing (drying). Windows, being the coldest spot will attract the warm moist air causing condensation. Therefore exhaust fans in all areas (bathroom, laundry, kitchen) must be used to reduce the relative humidity and minimize high moisture content.

Water stains on natural wood can be removed by mixing a solution of equal parts white vinegar and warm water. Scrub the stained area with a small stiff bristle brush and blot dry with a towel. Continue this process until all visible stains have been removed. Rinse well with clear water. Dry with hair dryer until clear surface obtained. Use clear solvent based urethane for finish ie. FLECTO VARATHANE # 90, 91 or professional grade. Apply two coats with a light sanding in between.
