How to Remove Black Mold on Windows

Discovering mold on windows is not uncommon if condensation is a problem. However, by doing some investigation work and following a few simple steps, you can easily find and rectify the cause as well as prevent it from reoccurring.

Step 1 – Examination

Begin the process of removing mold on windows by identifying every point where it exists. Examine the glass and frames of the windows thoroughly to make sure that you know where every instance of mold occurs. This makes it easier to remove it all at the same time. Do not overlook the inner surface of the window frames; open the windows and check inside thoroughly.

Step 2 – Dry Clean

If, when you come to clean the mold on windows, the panes and frames are dry, begin by using a vacuum cleaner to remove any loose spores. Undertake this process when the window is open to allow the particles of mold an escape route. Slowly and steadily run the nozzle of the hose over the glass and the frames to make sure you cover every section. Once complete, clean the vacuum nozzle with a cloth dampened with vinegar.    

Step 3 – Wet Clean

Avoid using a vacuum if the windows are wet. Instead, put on a pair of protective gloves and use a cloth that has been dampened with tepid water to wipe the panes and frames of the windows. At this stage, your action should only be to remove the excess of the mold on windows. Avoid rubbing too hard to avoid forcing mold spores into the wood of the window frame. Regularly rinse the cloth in clean water.  

Step 4 – Mold Removal

Once the excess mold has been removed, you will be in a better position to determine the full extent of the problem. Where the problem is relatively minor, spray some white vinegar onto the windows and leave it for a few minutes as you gather some baking soda onto a clean cloth. This can then be used to rub away the mold as the baking soda will act as an abrasive and the vinegar will kill the spores. If the problem is more extensive, dilute some fungicide in a bucket of water in accordance with the instructions and use this to clean the glass and frames of the windows.

After removing the mold, dry the surface thoroughly with a cloth and inspect it to ensure that there are no final traces of mold. If so, repeat the cleaning process again.

Step 5 – Prevention

Prevent mold from returning by keeping the windows condensation-free. This can be achieved by wiping condensation away with a dry cloth. Wherever possible, keep the window ventilated so that air can circulate and prevent the area from becoming damp.
