  • Eye irritation – If you notice tired, bloodshot, or dry eyes, then you may have a mold problem. It can also cause itchy eyes. 
  • Rashes – Mold spores can also cause dry skin, and this leads to rashes. You can only cure these skin conditions by removing all the mold. 


How Does Mold Grow On Windows?

Ironically, windows always get wet yet they are the part of the house normally overlooked by homeowners. Sometimes it’s difficult to clean the window sills, so you might not notice mold until it’s already severe.

Humidity is the biggest culprit of moisture buildup in your windows. You should find ways to keep air circulating in your home.

Condensation can also lead to water damage to your windows. Check that your framing is secure and there’s no moisture in the corners.

Leaks from pipes or the roof can create the perfect breeding ground for mold. Keep all your fixtures in good condition.


Step-By-Step Process On Removing Black Mold

Now you know how mold can get on your windows, it’s time to clean it off. You can find most of the cleaning materials you need in your cabinets, but remember to get the help of professionals if the damage is too severe. Use protective equipment like gloves and goggles, so you don’t get exposed to the spores. 


Step #1. Apply moisture to the area

Use a spray bottle and fill it up with water. Spread it on the area where the mold is growing. The water will stop more spores from flying around.


Step #2. Wipe the mold away

Make a cleaning solution of dishwashing liquid or vinegar with water. Wait for the mold to absorb the water you sprayed, then apply your cleaning solution. Use a clean cloth to wipe the area and repeat it as often as needed.


Step #3. Clean with a bleach solution

When you’re finished wiping off all the mold, you need to make sure there aren’t any spores left. Make a mixture of bleach and water, then put it in a spray bottle.

Apply it all over the area and leave it for a few minutes. Soak all the tools you used in bleach so the spores don’t spread. 


Step #4. Leave the area to dry

Drying is an essential part of your cleaning. Use a cloth to wipe off the remaining liquid, then allow it to sun-dry. You can use an electric fan or hairdryer to speed up the process if there’s no sunlight. 

Drying the area can kill any remaining spores. Here’s a guide on how drying an area can affect mold growth.
