How I Managed To Kill Black Mildew On Wooden Windowsills

Since cold season is still lingering around our gorgeous places, killing those nasty viruses and enjoying us with the delightful snow on the outside, I can’t say that it creates the same enjoyable moments on the inside. Yes, we might delight ourselves with a mug of mulled wine or cocoa in front of the fireplace – who owns one – but there is a small and smelly thing that happens in our homes during winter: black mold.

The low outside temperatures creates a phenomenon called condensation on our windows that will run down on the windowsill afterwards. This damp and moist environment creates the perfect place for mold and mildew to grow harmoniously, unless you remove the dampness and condensation on time. However, if mildew started to develop on your windowsill, somehow you have to remove it A.S.A.P. otherwise it will spread rapidly and it will make it even hard to remove, especially if you have wooden windowsills. As wood is a bit porous sometimes, you have to insist in cleaning it, otherwise mold will reaper. This means that mold spores are not completely removed.

First Mildew Removing Method:

Supplies Needed:

  • 1-gallon warm water
  • 1-cup borax
  • long-handled spoon
  • cloth

How To Use:

Fill a bucket with 1-gallon warm water. Add 1-cup borax to the water and mix thoroughly with a long-handled spoon. Saturate a clean cloth in the mixture and wring out the excess liquid. Scrub the windowsill clean with the damp cloth.

Second Mildew Removing Method:

Supplies Needed:

  • spray bottle
  • white vinegar
  • 1-cup oxygen bleach
  • 1 gallon of water

How To Use:

Mix 1-cup oxygen bleach with 1 gallon of water and pour in a clean spray bottle and spray the mildewed window sill with the mixture and let sit for 10 minutes. Dampen a clean cloth in cool water and wipe the mildew with the cloth. Then fill another empty spray bottle with undiluted white vinegar. Spray over the windowsill and let it work for 10 minutes and use a damp cloth to wipe the area.

!!! Neither vinegar nor oxygen bleach will damage, discolor or harm surfaces.
