Limestone is easy to care for making it a great choice for kitchen worktops, bathroom tiles and flooring indoors and out. Ideally, limestone should be professionally sealed. As well as making it easier to clean and care for, this ensures that no bacteria or dirt can get trapped in the surface and reduced the chance of scratches and stains.
It’s as simple as starting with soap and water. Limestone is waterproof, heat resistant and impervious to most scratches and stains once it has been sealed. As a result, most day-to-day care can be accomplished with a damp cloth. Wipe up spills immediately, and wipe down your worktop regularly or mop your floor to pick up dirt and bring up the gloss.
Don’t Chop Food Directly on Your Limestone Worktop
Calcium carbonate is often used in indigestion tablets, so it’s certainly not harmful and sealed limestone worktops are food safe, so by all means roll out your pastry on your worktop. However, using a sharp knife on stone isn’t good for either knife or worktop – the knife will blunt more quickly and the stone work top may develop a dull patch as tiny scratches accumulate over time.
Never Use Lemon Juice on Limestone
Lemon juice, vinegar and other mild acids are popular natural cleaners. Here’s why you should never use vinegar on limestone. Limestone is primarily made of calcium carbonate (CaCO3). In its pure form, calcium carbonate is a white solid and it’s found in everything from chalk to marble. If it comes in contact with an acid, such as lemon juice, it splits into a salt (not for eating!), water and carbon dioxide. Even if you can’t see the reaction, it can quickly dull a high-gloss polish, leave pitting or other marks.
Never Use Harsh Cleaners on Limestone
Limestone can also be damaged by the strong chemicals in harsh cleaners. Instead of reaching straight for the bleach, start with a damp cloth. Washing up liquid is designed to get rid of grease and food marks, so is a great next step.
Use a Specialist Limestone Cleaner
If you want to bring your stone back to it’s as-new high-gloss finish, a specialist stone polish is key. These are specially formulated to enhance the look of the stone without damaging it. Most people find they don’t need to apply the polish often as the limestone stays looking great without it, but for special occasions you may want to go that extra mile.

Cleaning a Limestone Patio
Limestone is a great choice for a patio or garden path. Limestone tiles are often pale, and may become discoloured or dirty, particularly during the winter when they’re less used. Start by sweeping away any build up of dirt and leaves, then use a stiff brush to firmly sweep soapy water across the surface. If this doesn’t have the effect desired, you may wish to hire a pressure washer or use a specialist stone cleaner.
Dealing With Years of Neglect
If you’ve just moved into a property, you may be dealing with a limestone worktop, floor or tiles that haven’t been properly cared for. In this case, a specialist cleaning and renovation service may be your best choice as they will have access to specialised cleaning products and equipment that you just can’t buy in the supermarket. If you need to repair or replace your Limestone worktop, flooring or other home feature, you can view our premium range of Limestone or speak to one of our natural stone experts.
If you prefer the DIY route, expect to need several goes at the project as you take layers of dirt off. Start gently, with soap and water and upgrade to a specialist stone cleaner if required. Limestone is unlikely to be damaged by scrubbing but it can be harmed by harsh chemical cleaners.
