How to Clean Limestone

Basically, limestone can be cleaned just like other floors and does not require any extra care. Outside, the panels are simply swept away or washed away with a water hose. Sweep, vacuum, or mop, and the floor inside is clean again.

But which cleaner is best for wiping limestone?

For the sake of simplicity, some people use the chemical club to remove stubborn dirt faster – better not! With limestone, make sure that you do not use acidic cleaning agents. Since limestone is a sedimentary rock made up of calcium carbonate and minerals, it reacts to acids.

Polished tiles can lose their beautiful surface gloss because if the acid is too strong, slight acid burns in the form of matt surfaces occur. It is better to use a mild soap cleaner or a cleaning agent suitable for natural stone, e.g. from Black Diamond Stoneworks. This is applied diluted with water and is suitable for regular maintenance. The basic cleaner can help with heavier soiling. This is basically all that is important for the care of limestone!

Care Instructions and Protective Treatment for Limestone

Prevent stains with an impregnator

Maintain the floor with an impregnator and prevent stains

In order that stubborn stains do not appear in the first place, it is advisable to impregnate the floor. Additional advantage: If the impregnator (e.g. 511 Impregnator Sealer) is applied to the limestone before grouting, excess grout residues on the limestone surface can be removed more easily.

The impregnator should be applied according to the manufacturer’s instructions. Impregnator makes limestone significantly easier to care for and less sensitive to dirt. The effect is achieved without changing the surface and cleaning the limestone is then much easier.

A refreshing of the care through impregnation is recommended every 4-5 years. In heavily used areas, such as the kitchen or bathroom, possibly even earlier.

Shine preservation

Limestone is an eye-catcher in its natural and original way, but it can be refined with an appropriate surface treatment, e.g. polishing. In order to maintain the polish and shine, add a shine care product to the mopping water about once a month.

Pro Tip!

If dull areas of the surface of polished limestone tiles lose their shine, they can be beautified again. Individual matt areas can be worked up with cream polish. This gives the polished surfaces additional protection and shine.

How to Clean Limestone in the Bathroom

Limestone in the bathroom is beautiful, but lime is extremely unpopular. Cleaning limescale stains, removing soap residue, combating urine scale, and so on is not your favorite subject?

Limescale stains

The easiest way here is prevention! If you remove or dry drops of water on the shower wall and fittings immediately after showering, it will be easier to clean.

If limescale stains or limescale edges have already formed, you should not use a vinegar cleaning agent as is usually the case, because as already described, limestone should not be cleaned with acidic agents.

Better to choose a basic cleaner that is suitable for natural stone and a white nylon pad for application. Rough sponges can leave slight scratches on the limestone surface.

Urine stains

Urine on limestone tiles can cause unsightly stains. In a similar way to the way urine scale forms in the toilet (namely, through a chemical reaction of urine with lime-containing water), discoloration also occurs when urine and limestone tiles react. Sitting down helps so that the stains do not appear in the first place!

Do not allow grease stains, oily barbecue sauce, or plant residues to dry up, but quickly remove them with a cloth. The same applies here: Choose an acid-free cleaner to clean stains on the limestone.

The use of a high-pressure cleaner is not necessary and also not recommended, because if it is used with too little distance and too much pressure, it can roughen the surface structure of the limestone. The stone is clean at first, but new dirt can later accumulate more easily.
