Whether your house has vinyl or wooden windows, one thing is sure: window sills and tracks are attacked by filth and grime from inside and out. In addition to keeping your windows looking their best, knowing how to properly clean the sills, tracks, and glass on your windows will ensure they function correctly.

Though this task may seem overwhelming, fortunately, it simply takes a few common home materials and some time to restore the appearance of your windows.

Window Sill Cleaning Equipment

Make sure you have the right tools before you start cleaning your window sills. To ensure that your window sills are spotless, you’ll need the following items:

  • A pail of warm water
  • Dish soap or vinegar
  • Borax
  • Microfiber cloth
  • Old toothbrush
  • Vacuum with a brush attachment
  • Spray bottle

Use a Vacuum To Remove Dirt And Dust.

Be careful to dust the drapes and blinds first since any dust disturbed above the sills will end up on the sills. Top-down cleaning is the term for this technique, and you may use a microfiber cloth or a duster to do it.

After that, pull out your vacuum (use an attachment) and use it to suck up as much free-floating debris and dust as possible off your windowsill. Take the chance to clean your window tracks of dead bugs and dirt. Removing this type of debris is much simpler to perform while dry than wet, so reserve the spray later on in the procedure.

Window Sillies Deep Cleaning

After you have dusted and removed the more easily removable debris, the next step is to remove the dirt and grime that has become tougher and more adhered to the surface over time.

  • Use a simple solution of dish soap or vinegar or another dish soap mixed in a pail with water.
  • Now, apply the solution to a microfiber cloth and clean the sill. Ensure the cloth is moist but not dripping wet to prevent filthy water runoff!
  • Use a tiny brush, such as an old toothbrush, to clean and pull dirt off corners and edges to remove more difficult-to-remove filth and grime.
  • Dry everything around with a microfiber cloth.

Helpful Hint for Cleaning! To clean and dry your microfiber cloth, fold it twice to have a moist portion for cleaning and a dry piece for drying.

The Presence of Mold On The Sills Of The Windows

Some may have discovered mold growth on your window sills. Luckily, there is a treatment for it too.

If you follow these instructions, you won’t have to worry about doing this work for a while:

  • 1/2 cup Borax
  • 1/2 Cup Vinegar
  • 2 Cups of Warm Water

Use a cloth made of microfibre to spread it over the afflicted region, or spray the area thoroughly with it using the spray bottle and let it settle for 10 minutes.

Use an old toothbrush to remove the mold in the cracks and crevices.

Repeat the procedure if it’s necessary.

Following application, the mold spores will have been eliminated, and the Borax will slow the development of any remaining spores on the surface. Use a cloth made of microfiber to ensure an excellent drying process.

Use a Cloth and Some Sort of Cleaning Solution to Wipe Everything Down

The last step in this procedure is also the least difficult one. All that’s left is to spray a microfiber cloth with an all-purpose cleaner and wipe away any debris stuck to the surface after you’ve removed most of the filth and mold. This should be done in the same manner that you would clean baseboards or wooden trim in other areas of your home. You can also use this tactic to clean scuff marks off of your walls!

After you have finished this process, you should open your windows to allow the air to dry them and then take pleasure in how much brighter and cleaner your area will seem.

Cleaning a Wooden Window Sill

Wooden window sills offer a pleasant touch to houses, but they demand a bit more upkeep and care than vinyl. Regularly exposing a wooden window sill to the sun, cold, rain, and filth can eventually lose its luster and even sustain damage.

Learn how to clean window tracks and sills on wooden windows to protect your windows:

A Painted Wooden Window Sill Needs to Be Cleaned

  • Before washing, use a soft bristle brush to remove paint flakes and dirt if the paint is peeling.
  • To clean the window sill, use water and dish soap with a gentle scouring pad.
  • Mix your cleaning solution with baking soda and gently scrub the area to remove stains.
  • Rinse the window sill with warm water and dry it with a cloth or allow it to drain through the weep holes.

The Right Way to Clean Window Sills That Have Been Stained or Varnished

  • Window sills and tracks may be cleaned with a soft bristle brush and soapy water.
  • Rinse the window tracks and sills well and promptly remove any surplus water so that it does not sink into the wood.
  • If you see any watermarks or stains, lightly sand the surface using fine-grade sandpaper.
  • Apply a new coat of varnish or stain to restore the surface when the window sill has dried thoroughly.

Think About How Often You Should Clean the Sills of Your Windows

After a significant amount of time and usage, the windowsills will get filthy. If you live in an environment where you can only open your windows for a few months, you will only need to do one to two cleaning sessions on your windowsills per year. People often use spring as an excuse to deep clean, learn more here!

On the other hand, you will need to clean the windows every couple of months if they are utilized throughout the whole year. Because mold may cause various health problems, it is essential to keep an eye out for its growth and remove it as soon as you discover it in your house. And if you don’t feel like doing the labor yourself, you can always hire someone to clean your windows.
