How do I clean mildew that formed around the interior of my windows?

Bleach will clean it. Vinegar will kill mold spores. Do not mix the two. The fumes are harmful.

Ways To Prevent Window Condensation and Mold

There are three main approaches to preventing condensation and mold on windows and window seals. Each of these approaches can be accomplished in several ways.

Approaches 1 and 2 prevent condensation on windows and surfaces, while approach 3 allows condensation to occur, but removes it before it has been present long enough to cause mold growth or other problems. Used singly or, more effectively, in combination, these approaches will help to reduce condensation during colder weather as a cause of mold growth. Discussed in detail below, these approaches are:

Increase surface temperature of window glass and frameReduce dew point temperature (humidity) of the air in the roomAbsorbing water and cleaning window surfaces regularly

Hello Mindy! Do you live in a cold climate that causes your windows to condensate? I do and I can have condensation around the interior edges of my windows and along the center section where the double hung windows meet and lock. When it is extremely cold I can also get ice/frost as well. To solve this problem I install shrink window kits on my windows every year before winter begins to eliminate this issue. Even though I have newer good quality windows that are less than 10 years old the interiors are wood framed and I do not want them to get mold in that area or deteriorate over time from that condensation/ice/frost. The window kits also keep the cold drafts out and are very energy efficient for my area of the country. Although I do not like looking at the plastic for about 5 months every year I try to hide the plastic look by hanging sheers over those windows. WIndows are too expensive and when we replaced ours about 8-9 years ago I thought I could get by without the plastic shrink kits but it is just TOO cold in the winter where I live!

White cleaning vinegar will kill the spores. Then you can clean windows as usual. You might use hydrogen peroxide.

I use q-tips dipped in vinegar to clean the crevices.

Hello Minda,

Clean it off with Soapy water and a toothbrush, or use Meth's or Surgical spirit. Wipe it dry. Sounds as if there is a lot of warm air hitting cold windows. Maybe a little more ventilation would help!
