Removing mold is hard

Mold and mildew removal from wood surfaces in a home is a hard and tedious process. It takes persistence, promptness, and professional help to get rid of them.

Mold is a nagging problem that we all encounter in our homes frequently however clean we are. It quietly sneaks in and if humidity is present, combines with it to create a problem that calls for urgent attention. Wood attracts molds because of its absorbent nature. The water it absorbs provides the perfect environment for breeding mold.

Removing mold from wood is difficult and can take long to completely wipe it off. It's hard because

  • Wood is porous meaning removal of all spores is challenging.
  • It involves a long process that makes the elimination dangerous when inhaled.
  • Poor removal causes it to spread further.
  • Using the wrong solutions will only scratch the surface but not completely clear it.

You may attempt to remove them yourself but if it becomes problematic and resistant, enlist the services of professionals. They will address the root cause of the problem and ensure your home is mold-free.


How do you get mold stains out of wood?

Before you remove the stains, ensure you're safe by dressing in appropriate gear that covers your skin. Use an air mask to avoid inhaling mold spores. Shield your eyes with eye goggles as the mold irritates eyes. Protective clothing and rubber gloves keep mold spores from your clothing and skin .

Clean the area in question or vacuum clean it to curb the spread of the molds. Study the wooden surface to determine what type of treatment to use. The wood may be painted or untreated.

If it is painted, wiping the surface with hot water and any detergent will resolve the issue. This is because the mold cannot penetrate through paint or any treated wood.

For untreated wood, clean the surface with water, detergent, and some bleach. What most people struggle with is, “Does bleach kill molds?” It helps kill molds if used with water and works only if the mold is on the surface. After sponging the mixture on the wooden surface, let it dry or use a dehumidifier to dry the area faster. This is necessary as excess water on the wood increases mold growth.

To remove the mold stains on the clean surfaces, consider further deep cleaning. Since the stains are hazardous to your health, extra caution is advisable so that you don't increase mold growth instead of getting rid of it. Sanding the affected and cleaned area removes the mold stain. If the wood is darker, discoloration will occur. Apply varnish or new paint after coating the place with mold-killing primer to conceal the discoloration.
