Window tracks just love to attract lots of dirt and tough-to-scrub grime, but there is a simple solution to get the job done quickly and easily!

Watch how quickly the gunk melts away in this video tutorial on how to clean window sills using basic items you already have at home:

Spooning baking soda onto the dirty window tracks

1. Apply baking soda

Start off by sprinkling a fairly thick layer of baking soda into your window tracks. Press it firmly into the cracks and corners so that it does its job well.

It might look like a lot as you go, but as you can see in the video, it takes quite a bit of baking soda to get that shine. 

Pouring vinegar on top of the baking soda

2. Pour vinegar

Next, pour your vinegar straight onto the baking soda so that it bubbles up like mine did. Allow the mixture to rest and do its thing for 5-10 minutes. 

Scrubbing the mold with a toothbrush

3. Scrub with a toothbrush

Once it has been resting for a while, grab an old toothbrush and scrub all the dirt loose.

Soaking up the mess with a paper towel

4. Wipe

Then, wipe the loose gunk away with a rag or paper towel. Isn’t it amazing how it just slides away to reveal sparkling tracks? 

Happy green cleaning!

Pushing a knife wrapped in a towel along the edges

5. Clean the edges

For a deeper clean (when your windows are beyond yucky), try the kitchen knife trick; wrap a knife in a towel and push it into the edges.

    Can you use this method on wooden window sills? It looks like yours are metal.

    Not sure if aluminum likes vinegar. Please advise.

    I use my handheld steamer/attachments to clean my window tracks and patio door track also. They work very nice.
