Did you know that, aside from your glass and screen windows, you also need to clean your window sills and tracks? Nope? That’s okay if you forgot. It’s never too late!

If you don’t know where to start, keep scrolling below for a step-by-step guide on how to clean your window sills and tracks.

How to clean a dirty window sill

Whether in the suburbs or the city, window sills are bound to get a bit of dust on them. Old leaves, small tree branches, pollen, and pollution can hit your window sill and stick to them. Moreover, strong winds from rain can bring in dirt and grime. 

So, ensure you regularly clean them to prevent stains and mould from ruining your home.

Window sill cleaning tools you’ll need:

  • Microfibre cloth

  • Window cleaning solution

  • Spray bottle

  • Floor wax

  • Soft-bristled brush

  • Bucket


Don’t know how to clean the inside of a window sill, a painted window sill, and a cement window sill? Follow these tips for an easy cleaning process you’ll soon be able to master! 

  1. Use a soft-bristled brush to gently dislodge dust and grime from your window sill. Make sure you have a bucket underneath to catch the dust.

  2. Mix a few drops of dishwashing liquid and warm water. Then, pour your cleaning solution into a spray bottle. See some large stains on your window sill? Add a bit of baking soda to your solution.

  3. Spray your cleaning solution on a microfibre cloth—not the window sill itself, as it can damage the paint—until the cloth is damp.

  4. Gently wipe the window sill and frame. If the stains are still there, wipe a bit harder. Add more cleaning solution to the cloth if it’s starting to dry.

  5. Wipe the window sill again with a dry and clean microfibre cloth.

  6. Apply a light layer of floor wax to prevent future dirt from building up and staining your window sill.

How to clean window runners or tracks

Even if you never open your windows, microscopic dirt, dust, and bugs will still find a way to get into your windows and stay in your window runners. It’s better to regularly clean them since packed layers of grime can be harder to remove later.

Window track cleaning tools you’ll need:

  • A small vacuum with a narrow nozzle

  • Butter knife or plastic putty knife

  • Microfibre cloths

  • White vinegar

  • Water

  • Spray bottle

  • Baking soda

  • Dry lubricant or a candle

  • Toothbrush (optional)


Before cleaning window tracks, ensure you’ve already finished cleaning your windows, as you don’t want more muck to end up in the tracks. 

  1. Open your windows as wide as possible and remove any window screens, if applicable. 

  2. Grab your vacuum with a narrow nozzle and start suctioning out all that dirt from your window tracks. Remember to thoroughly go through every nook and cranny!

  3. Sprinkle a light layer of baking soda. Ensure there are no large clumps or piles of baking soda anywhere.

  4. Mix equal parts of water and white vinegar and put it in a spray bottle. Spray the solution on the baking soda until it looks saturated. Let it sit for 5 to 10 minutes.

  5. Wrap a microfibre cloth around a small butter knife, and start wiping the solution off in one steady motion. The gunk should easily come off!

  6. Spray more of your DIY cleaning solution if some areas are harder to clean. Let the solution sit, and use a toothbrush to gently dislodge the dirt. 

  7. If needed, do a final spray with the solution and wipe it down with your clean microfibre-and-butter-knife tool. 

  8. If you find it’s still hard to open and close your windows even after cleaning the tracks, a little lubricant can help them glide as new. Apply a bit of dry lubricant or a candle to lubricate your window tracks. Then, operate the window several times to warm it up and spread it over the track.

  1. Dust your window sill weekly or every two weeks to prevent dirt from building up.

  2. Dedicate a few minutes weekly to vacuum your window tracks and check if any mould is growing on them or on your window sill.

  3. Check your windows regularly for any leaks, moisture, or other issues to prevent the growth and spread of mould. 

Clean your window sills and tracks with ease 

Keeping window sills and tracks sparkling clean doesn’t have to take a lot of elbow grease.

FAQs on cleaning window sills and window tracks

If your window sill is made of wood, you’ll want to buy a wood cleaner with oxalic acid. This alone can remove water marks from wooden window sills without harming the material. Follow the instructions on how to use it and make sure it dries before applying a fresh coat of paint to make it look as good as new.

On the other hand, if your window sill is made of cement or other materials, a simple cleaning solution of dishwashing liquid and warm water can remove stains.

Mix two teaspoons of dishwashing liquid, one cup of white vinegar, and one cup of water. Place it in a spray bottle and spray the affected area. Let it sit for a few minutes before wiping it off with a microfibre cloth. If your window sill is made of wood, don’t let the mixture sit too long because it can destroy the wood.

Use a simple cleaning solution made of gentle dishwashing liquid and water. Spray it on affected areas, let it sit for a few minutes, and wipe it off with a clean microfibre towel. Avoid cleaning areas using a dirty towel, as you might just spread the ash everywhere.

You can use the same processes mentioned above, but instead of using a vacuum to remove dirt and debris from window tracks, you can use a hair dryer! Position the dryer outwards to move the dust away from the window track so you don’t just move them somewhere else.
