Remove wood window discolouration and product best for protecting woodSeptember 24th 2007
Q: We have wood windows in our home and unfortunately in the winter they always get cold and wet in the inside and now the wood has been discoloured. What can we do to remove the water stains from the wood and what should we apply to keep the natural wood look but also protect it from happening again?
A: Wood window frames and sashes 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. Windows can be the coldest spots in the home and will attract warm moist air, resulting in condensation and wet windows. Exhaust fans in areas such as bathrooms & kitchens must be used to reduce the relative humidity and minimize high moisture content. Leave bathroom fans on for minimum one hour after every bath or shower.
The water stains on your natural wood windows can be removed by mixing a solution of equal parts white vinegar and warm water. Scrub the stained area with a small bristle brush and blot dry with a towel. Continue the process until all visible stains have been removed. Rinse well with clear water. Dry with a hair dryer until clear surface is obtained. Use clear a solvent based urethane for finish i.e.; Flecto Varathane. Apply two coats with a light sanding between coats.
