Limestone is a natural stone often used in bathrooms and kitchens, but it may also be found in other areas of the home, such as windowsills. As is the case with other natural stones like marble, using the wrong cleaners can harm limestone. Many commercial cleaners specifically made for natural stone are available. Using these to clean your limestone windowsills is preferable to a general household cleaner, unless the label states that you can use it on limestone.
Things You'll Need
- Rubber gloves
- Safety glasses
- Stone cleaner
Put on rubber gloves and safety glasses. Spray stone cleaner all over the windowsill if you purchased it in a spray bottle, or pour it in a bucket and mix with water according to the directions if you purchased a concentrated form. After mixing it, apply it to the sill with a soft sponge.
Scrub the limestone windowsill until the sponge is dirty. Rinse the sponge in clean water and apply more stone cleaner to the windowsill. Scrub it again with the sponge, and repeat the process until no more soil transfers to the sponge.
Rinse out the sponge. Wipe the windowsill with the rinsed sponge to remove leftover cleaner.
Buff the limestone windowsill with a soft towel to dry it.
Tips & Warnings
- Do not use household cleaners, including homemade ones (such as vinegar) on limestone unless you know they are acceptable for use on stone. Even mildly acidic cleaners can damage limestone.
