Due to its stunning apperance, limestone is a popular natural stone for use in both indoor and outdoor areas. It's also incredibly versatile, as it can be cut to varying sizes and finishes. However, to maintain the look of your limestone surfaces, you'll need to ensure you're caring for them appropriately.
Here's our guide to cleaning and maintaining limestone in the home and garden.
What to consider before cleaning Indonesian limestone
Outdoor limestone walls and tiles are exposed to the elements and as a result can become covered in sand, mud and other substances. Indoor limestone surfaces can also become marked with stains from food and drink spills, as well as general dirt and dust.
An important thing to note is that natural cleaning solutions that can be used on other surfaces – such as baking soda, for example – will be ineffective on limestone surfaces. In fact, they could potentially even damage the stone. This is due to two reasons:
- Limestone is porous: This means it absorbs liquids easily.
- Limestone is calcium based: This means that it reacts badly with acidic substances.
Bearing these things in mind, you'll need to take care when cleaning or removing stains from your limestone walls, floors or benchtop areas. Avoid acid-based cleaners containing ammonia, vinegar or citrus, as these will damage the surface. You'll need to ensure that any cleaner you use is pH neutral.
How to clean Indonesian limestone
Over time, the sealer that was applied to your limestone surfaces will wear away, and you'll need to reapply it regularly to prevent damage. You can get hold of limestone sealer from a local DIY store.
Here are some additional limestone cleaning tips:
- Floors: Dry mops and brooms are ideal for removing debris. You can also use a vacuum cleaner, but be sure to switch off the spinning brush to avoid scratching the surface. Then, you can mop or wipe the tiles using a non-acidic cleaner. Be sure to rinse your tiles with warm water after using the cleaner to reduce any stickiness.
- Rough outdoor walls: Gently rinse your walls with a hose to remove dirt. Then, use a non-acidic, neutral cleaner to wipe the surface area down with a soft-bristle scrub brush. Rough limestone surfaces can be left to dry naturally.
- Polished benchtops: Rinse the benchtops with water before wiping the surface down using a neutral cleaner with a soft, lint-free cloth, so as not to scratch the surface. You can then dry the benchtop with a towel or cloth.
How to remove stains from Indonesian limestone
If you've got stains on your limestone surfaces that you can't remove with water or cleaner, you'll need a tougher solution. One option is to mix together a 'poultice', a paste made up of ¾ cup of flour and hydrogen peroxide. Simply rub the paste on the stain and leave it to harden (this could take one-two days). Then, use a spatula to remove the poultice. Just be careful not to use any metal products to do this, as these will damage the limestone.
