Ever looked at your window sill and noticed some mysterious dark spots? Chances are, you're dealing with spider poop.

Believe it or not, it's more common than you might think!

Our eight-legged friends are great for keeping other bugs in check, but their droppings can be a real nuisance. And cleaning it can be really hard once it’s dried.

But fear not - I’m here to help.

In this post, I’ll show you how to clean spider poop on window sills step by step.

What Does Spider Poop Look Like?

Spider poop looks like small, dark spots. It's basically what's left after spiders digest their food (mostly bugs) mixed with other waste.

How To Clean Spiders Droppings On Windows

When spider poop is fresh, it's pretty easy to clean up because it's still kind of liquid. But once it dries out, it can be really tough to get rid of.

It might even leave these yellowish stains behind.

But don't worry, here’s a method that works well and won't break the bank:

#1 Prepare The Area

First things first, let's get that window sill ready.

Grab a water hose or a damp cloth and give the sill a good rinse. This will get rid of any loose dirt and make the rest of the cleaning easier.

While you're at it, clear away any cobwebs or other spider stuff you see.

We want to start with a nice clean surface.

#2 Mix The Cleaning Solution

Now, let's make our cleaning mixture.

Get a bucket and pour in 1 gallon of cool water. Add 1 cup of oxygen bleach to that and stir it up with a long spoon until the bleach is all dissolved.

We're using oxygen bleach because it's safer than the chlorine one.

It won't hurt your plants if you spill it, and it won't mess up your clothes either. Plus, it's not as harsh on surfaces but still does a great job on spider poop.

#3 Apply The Solution

Time to get that solution on the window sill.

You can use a scrub brush with a long handle - just dip it in the mixture.

If you've got a lot of area to cover, you might want to use a pump sprayer instead. Fill it up with the solution and spray it all over the sill.

Oh, and don't forget to wear gloves to protect your hands.

If you're working overhead, you might want to wear something to protect your eyes too.

#4 Scrub The Affected Area

Now comes the fun part - scrubbing! Start working on those spider droppings. Push down firmly, but be careful not to damage the surface.

It's best to work in small sections, and really focus on areas where there's a lot of poop built up.

The oxygen bleach in the solution will help break down the droppings, making them easier to scrub away.

#5 Let The Solution Work

After you've scrubbed everything, leave that bleach mixture on the window sill for about 10 minutes. This gives it time to really work on those stubborn droppings.

#6 Rinse Thoroughly

Once those 10 minutes are up, it's time to rinse. Use your water hose again, or a clean, damp cloth.

Make sure you get all of that cleaning solution off.

This rinsing step is really important - if you leave any of the bleach solution behind, it could damage the surface over time.

#7 Repeat If Necessary

If you still see some spider droppings after all that, don't worry. Just go through the process again until they're all gone.

Some really stubborn stains might need a few rounds of cleaning.

Just be patient and keep at it - you'll get there!

Commercial Cleaners That Can Remove Spider Poop

The water and bleach method works great, but there are also some store-bought cleaners that can do the job:

SoftScrub Cleaner

SoftScrub is pretty handy for cleaning up spider poop. It's got a creamy texture that sticks well to vertical surfaces, which is perfect for window sills.

Here's how to use it:

Put some SoftScrub directly on the spider poop and let it sit for a few minutes. This gives it time to start working on the droppings.

Then, grab a scratchy sponge and start scrubbing. SoftScrub has some mild abrasives in it, along with cleaning stuff, which helps it lift even dried droppings.

When you're done scrubbing, rinse it all off with water and dry it with a clean cloth.

Scrubbing Bubbles

You might think Scrubbing Bubbles is just for bathrooms, but it actually works pretty well on spider poop too.

The foam helps lift and dissolve the droppings, making them easier to wipe away.

Here's what to do:

Spray Scrubbing Bubbles right onto the spider poop on your window sill. Let the foam sit there for a few minutes - this gives it time to work on the droppings.

Then, use a sponge or cloth to wipe away the foam and the droppings with it.

If you've got some tough stains, you might need to use a scrub brush.

When you're done, rinse everything off with clean water to get rid of any leftover cleaner.

Mr. Clean Magic Eraser

Magic Erasers are pretty cool for cleaning all sorts of things, including spider poop.

They've got these tiny scrubbers in them that can lift even dried droppings without needing any harsh chemicals. Here's how to use one:

First, get your Magic Eraser wet and squeeze out the extra water. Then, gently rub it over the spider poop on your window sill.

You'll see the eraser start to break down and remove the droppings.

When you're done, wipe the area with a damp cloth to get rid of any bits left behind.

Just be careful if you're using it on painted surfaces or delicate stuff - sometimes Magic Erasers can take off paint or finishes.
