How to Clean Window Sills (Exteriors Included!)

How to Clean Window Sills

Window sills are one of the most commonly overlooked areas for cleaning. People often think that they don’t need to clean them because they’re not visible from the inside of the house. However, window sills can get just as dirty as any other part of your home – and sometimes even dirtier since they’re exposed to the elements! In this blog post, we will teach you how to clean your window sills – both indoors and outdoors!

Why is it Important to Clean Window Sills?

Window sills are one of the first places that dirt and grime collect. This is unsightly, but it can also lead to further damage down the line. If left unchecked, dirt and grime can eventually eat away at the paint or finish on your window sills, leading to costly repairs.

If your window sills are dirty, they’re probably covered in pollen, dust, and who-knows-what-else. Ick! But don’t worry; with a bit of elbow grease (and some of these helpful tips), you’ll have them sparkling clean in no time.

Clean Window

There are a few reasons why you should keep your window sills clean. First of all, it just looks nicer! A clean window sill gives your home a polished and well-maintained appearance.

But more importantly, dirt and grime can damage your window sills. Over time, the build-up of dirt can lead to rotting or molding, which can be unsightly and expensive to repair. Cleaning window sills regularly will help prolong their life and keep them looking like new.

How to Clean Interior Window Sills (Indoors)

Start by dusting the surface of the window sill with a rag or paper towel. Be sure to get in all the nooks and crannies. Once they’re dust-free, clean the surface with vinegar diluted in warm water. To clean exterior window sills, you’ll need first to remove any loose paint or caulking. Use the putty knife and screwdriver to do this. Be careful not to damage the wood beneath. Once all the loose materials are removed, wipe the surface with a damp rag or paper towel and then clean with vinegar diluted in warm water.

Now that your window sills are clean, you can add the finishing touches! Dry them off with a clean rag or paper towel if you’re cleaning interior window sills. Then, using glass cleaner and a new rag or paper towel, polish the surface until it shines. For exterior window sills, apply fresh caulk around the edges (if needed) and then paint over any bare areas (if desired). Over time allow the paint to dry completely before adding any decorations or furniture back to the sill.

How to Clean Exteriors Window Sills (Outdoors)

Cleaning outdoor window sills are more challenging since they’re exposed to the elements. However, it’s still essential to do regularly – especially if you live in an area with high humidity or lots of rain!

The best way to clean outdoor window sills is with a power washer. Start by attaching the power washer to your hose and setting it to a low-pressure setting. Then, hold the nozzle about a foot away from the sill and slowly move it back and forth across the surface.

Once you’ve power washed the sill, start by climbing up to the window sill and removing any loose dirt or debris with your hands. Next, mix some warm water and dish soap in the bucket. Dip your sponge or brush into the soapy water and start scrubbing the surface of the window sill. Use a garden hose to rinse it off.

Finally, dry off the sill with a clean towel. If there are any stubborn stains or spots, you can use a mild cleaning solution (like dish soap and water) to remove them.

Types of Window Sills and How to Clean them

Different types of window sills will require different methods of cleaning. Here are some tips on how to clean various types of window sills:

Wooden window sills should be dusted with a microfiber cloth or feather duster. If they are filthy, you can use a mild soap and water solution. Be sure to dry the sill afterward so that it does not warp or rot.

Aluminum window sills can be cleaned with a damp cloth and dried with a soft towel. You may need to use a mild abrasive cleaner for tougher stains. Be careful not to scratch the surface.

Vinyl window sills can be cleaned with a sponge, or soft brush dipped in soapy water. Rinse with a clean, damp cloth and dry thoroughly.

Glass window sills should be cleaned with glass cleaner and a soft cloth. Be sure to wipe in the direction of the grain to avoid streaks.

Best Way to Clean

Cleaning your window sills regularly is the best way to prevent this from happening. In addition, it will also help you keep your windows looking their best. Here are a few tips on how to clean window sills, both inside and out:

All you need is a mild soap and some warm water for general cleaning. Mix your soap and water in a bowl or bucket, and then use a sponge or cloth to wipe down the window sill. Be sure to rinse away any soap residue with clean water when you’re finished.

If your window sills are particularly dirty, you may need a robust cleaning solution. You can make one by mixing equal parts vinegar and water. Again, use a sponge or cloth to apply the solution to the window sill, and then rinse away with clean water.

For tougher stains, you can try using a mixture of baking soda and water. Apply it to the stain and let it sit for several minutes before scrubbing with a brush or sponge. Rinse away the baking soda mixture with clean water when you’re finished.

Once your window sills are clean, dry them off completely. This will help prevent any water spots from forming. You can also dust them regularly to help keep them looking their best.

Step by Step Cleaning

Assuming your window sills are already clear of any cobwebs or insects, the first step is to gather your supplies. You’ll need a ladder (if cleaning exteriors), a putty knife, a screwdriver, rags or paper towels, vinegar, warm water, dish soap, and glass cleaner for this job. You may also want to wear gloves to protect your hands.

How often should you clean your window sills?

Ideally, it would help to clean your window sills at least once a month. However, if you live in an area with high dust levels or pollen counts, you may need to clean them more frequently.

Common Problems with Window Sills

Cracked, Chipped, or Damaged

If your window sill is cracked, chipped, or otherwise damaged, it’s best to repair it before cleaning. Otherwise, you run the risk of making the damage worse. You can use wood filler to repair the damage for minor cracks and chips. Apply the filler to the affected area and allow it to dry completely. You may need to replace the entire window sill for more severe damage.

Mold Spores and Mildew

Mold spores and mildew can also build up on window sills. If you see any mold or mildew, clean it as soon as possible. To clean mold or mildew, mix equal parts of water and vinegar. Use a sponge or brush to apply the solution to the affected areas. Let it sit for a few minutes before rinsing off with clean water. Dry the sill with a towel to prevent mold or mildew.

Stains

If your window sill is stained, you can use various household products to clean it. For example, you can use vinegar, baking soda, or even toothpaste to remove stains. Apply the chosen product to the stain and scrub gently with a sponge or brush. Rinse the cleaner with clean water and dry the sill with a towel.

No matter how often you clean your window sills, they’ll eventually look dull and worn. If this happens, you can sand down the surface and then paint or stain them to give them a fresh, new look.
