Since we moved into our house about two and a half years ago, I've periodically vacuumed the window tracks, but I've not done a deep clean to get them back to squeaky clean. And it shows…
As part of my spring cleaning, I decided it was time to deep clean the window tracks. And all I needed to clean them was 1 ingredient – vinegar.
First, I used the attachment on the vacuum cleaner to vacuum out the window tracks. However, that still left a lot of dirt that had blown in over the winter. So, I took a small bowl of distilled white vinegar and first dipped strips of paper towel in it to clean the larger areas. Then, I dipped Q-tips in the vinegar to clean the corners and edges. If you prefer, you can use these window track cleaning brushes to make clean up faster than with Q-tips!
My window tracks cleaned up pretty easily, but if you have years of dirt caked on, you can try sprinkling some baking soda in the tracks and then spraying vinegar on it. The ingredients will react with each other. Once it's stopped bubbling, take a paper towels and Q-tips to clean out the dirt. You might need to let it soak for a bit longer for dirtier messes also.
