Cleaning Your Window Sills

Inside every home are certain places that we just sorta blow over and neglect cleaning, sometimes for years, such as your oven, the area behind a range, areas behind your washer and dryer, and not just the windows, but the actual window sills. If you get and look right this second, you’re sure to see a layer of dirt, spider webs, a dead fly or two that relentlessly banged up the window to escape to the outside only to fail and die a horrible death of starvation on the sill.

On this post, we are going to go thru some steps and show you how you can clean your window sills in no time at all. Here is a tip right off the bat though, this works best when you decide to clean your entire windows. This means cleaning the outside glass, the inside glass, and thoroughly washing the screens. So without further ado, here is how to clean your window sills and leave em spotless!

First Off, Vaccum The Sills First With A Narrow Attachment

The first thing you’ll want to do to start to clean your window sills is to make sure you vacuum up as much as the loose dirt, bugs, and debris that is sitting on the sills. Loosen it up a bit with a small brush, like a toothbrush, and suck away! It. don’t gotta be perfect. You just gotta get the large stuff first. Do it to all of your window sills.

Use Baking Soda And White Vinegar As Your Cleaning Solution. 

Next, sprinkle some Arm & Hammer baking soda into the sills. Don’t be shy or cheap with the stuff! You can get a box for only a couple bucks so be liberal with it. Next, use your white vinegar to slowly pour a small amount all over the laid out baking soda. This will create a bubbly reaction that will break up all the caked on dirt. It will be like science class again and them cool volcanoes you made and erupted in a presentation to get you solid A+ and some well-deserved praise from your parents and teachers, except this time you’ll be getting praise from your spouse this time. Let the solution sit for a while and let it work its magic. Scrubbing is for suckers!

Next Use A Wet Dry Vac And Suck Up All The Juice On The Sill.

We all got a wet dry vac in the garage, don’t we? You don’t! Well then skip this step and go to the next one. If you got a cool wet dry vac, bring it in the house and start to vacuum up all the juice or that volcano solution right out of the sills with a narrow attachment. Finish it off with a roll of paper towels and leave those sills looking amazing! You’ll have window sills looking so clean that it will look like you got new windows installed! Your neighbors will be so jealous!

The Final Step To How To Clean Your Window Sills.

Don’t get a wet dry vac? No prob! You can simply use some old rags or rolls of paper towels absorb all of the juice you left behind with your white vinegar and baking soda solution. Simply, absorb as much as you can with a first few dabs of the towels and then finish it off like you normally would.


You got yourself some awesome looking window sills. That’s all there is to it. Next time you need to clean your window sills, all you’ll need to remind you is when you go out to get a brand new box of Arm and Hammer baking soda to replace the old one from your stinky fridge.
