First and foremost, make sure you have all of the necessary tools and equipment you will need to thoroughly clean your window tracks and sills.

Most of these tools or products can be found within your home or online or at local stores at affordable prices.

White Vinegar is a natural deodorizer and is also anti-bacterial, making it an excellent cleaning agent. Once you have mixed up your solution it can be stored and used indefinitely.

Baking Soda

Baking Soda is another excellent all-natural cleaning agent. Like White Vinegar, it is a natural deodorizer and has anti-bacterial properties. You should be able to find baking soda in most grocery stores and it’s generally very affordable.

Butter Knife or Metal Skewer

Finally, you will need a butter knife, metal skewer, or similar narrow tool for digging into hard-to-reach places on your window tracks and sills. Avoid anything too sharp to prevent scratching of the surfaces.


It might seem a little obscure, but toothbrushes are incredibly useful when it comes to cleaning hard-to-reach spots within the home!

Now you are ready to get on to the step-by-step guide on How to Clean Window Sills and Tracks.

How to Clean Window Tracks

Now that you have all of your tools in order, it’s time to get on with deep cleaning your window tracks before focusing on how to clean window sills. Before doing so, though, we recommend that you start by cleaning your glass window panes. We suggest using the microfiber window cleaning cloths from e-cloth for an easy, streak-free clean window. Cleaning the glass after cleaning the tracks and sills is likely to result in dirt from the window panes falling or running down into the tracks, undoing any hard work you may have put into cleaning the tracks.

To clean your window tracks, start by taking your vacuum’s handheld attachment and sucking up any large pieces of dirt or dust from the tracks. This is the quickest way of removing surface-level dirt from this area. If your vacuum doesn’t have a handheld attachment, go in with a dry brush, natural cleaning wipes, or microfiber cloth, both will work well at picking up and removing dirt from the crevices of the window track.

Follow this by taking your butter knife or similar tool, covering it with your microfiber cloth or an old rag, and digging into any especially hard-to-reach spots where dirt has built up over time. Use the cloth and knife to pull the dirt out of these areas.

Next, sprinkle a light dusting of baking soda over the entire window track. Don’t be too liberal here, you want just enough baking soda to coat the surface, but you don’t want any large clumps of baking soda.

Then, spray your cleaning solution over the top of the baking soda and allow this to sit for several minutes. The baking soda and white vinegar should react with one another and fizz slightly. After this has been left to sit for a little while, take the toothbrush and scrub the window tracks from top to bottom.

Finally, go in with your microfiber cloth and remove as much of the cleaning solution and any residual dirt as possible. You might then need to rinse the cloth out and go back in to remove any dirt or cleaning solution that remains on the window track. You can also go back in with your knife and cloth combo to remove any baking soda or dirt that has been pushed into the corners of the window tracks.

Now, you should be left with sparkling clean window tracks to match your gleaming glass window panes!

How to Clean Window Sills

Time to move on to the window sills…

To do this, you should follow a similar method to the one listed previously. Start by removing any surface-level dust or dirt using a clean, dry microfiber cloth. If the window sill isn’t too dirty, you can bypass the baking soda and simply go in with your DIY cleaning solution and a damp microfiber cloth to clean the surface, however, if you have any stubborn stains or sticky residue on the window sill, the baking soda should do a good job of getting rid of these.

Treating Mold or Mildew on Window Sills and Tracks

Mold and mildew are commonly found on window sills and tracks. These tend to be areas where excess moisture or dampness can accumulate as a result of condensation or leaks.

If you find you have mildew or mold growing around your window, simply use the baking soda and white vinegar combination we have listed earlier in this article.

Prior to carrying out your deep clean, cover the mold with baking soda and then apply your DIY cleaning solution, allow this to soak in for up to 10 minutes before wiping away with a clean cloth. If the stain remains, you could consider using some hydrogen peroxide to get rid of the discoloration, but be sure that the hydrogen peroxide is suitable for use on your window sill or track first, as it can be damaging to painted surfaces.
