Black stain from the rain.


Thank you for the great pro information.
Our problem is that the previous owner of the house we just moved in has let one of the outside doors take the rain and there is now black stains on the bottom. I read on a French website (I’m from there…and my Australian husband has got no idea about varnish work), someone talking about using bleach on it! I’m a bit surprised, it there a better way?
Thanks a lot!

  1. Actually, at some of the commercial paint dealers you should find available a wood bleach for your need. I have always been careful to apply the bleach to the entire surface. I will be certain to use the most on the heaviest stains. You will need to rinse well and allow to dry. Sand and try applying two coats of stain to help cover the discoloration.

  2. To remove black stains from the bottom of an exterior door caused by rain, start by mixing equal parts of white vinegar and water in a spray bottle. Liberally spray the stained area and let it sit for 10-15 minutes. Scrub the stain with a stiff-bristled brush to loosen the dirt and grime. Rinse the area with clean water and dry thoroughly. If the stain persists, create a paste using baking soda and water. Apply the paste to the stain, scrub gently, then rinse and dry. For tougher stains, consider using a commercial cleaner formulated for outdoor surfaces. Prevent future stains by applying a clear sealant to the bottom of the door to protect it from moisture and dirt buildup. Regular maintenance, such as cleaning and sealing, is crucial to preserving the integrity and aesthetics of your exterior door.
